INTRODUCTION: Jasminum officinale L. is a very important medicinal and industrial flowering aromatic plant.
METHODS: The present study deals with Jasminum officinale L. leaves extract (JOLE) as a reducing and capping agent for the synthesis of silver nanoparticles (AgNPs) by the green pathway. Phenolic profile of the extract was evaluated using HPLC-PDA/MS/MS technique. Jasminum officinale L. leaves extract silver nanoparticles (JOLE-AgNPs) were characterized by ultraviolet light (UV), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), zeta potential and X-ray diffraction (XRD). JOLE-AgNPs were examined for their cytotoxic activities by neutral red uptake assay (NRU) against bladder (5637) and breast cancer (MCF-7) cell lines.
RESULTS: HPLC-PDA/MS/MS tentatively identified 51 compounds of different chemical classes. UV spectra showed absorption peak at λmax = 363 nm. The biosynthesized AgNPs were predominantly spherical in shape with an average size of 9.22 nm by TEM. The face cubic center (fcc) nature of silver nanoparticles was proved by XRD diffractogram. JOLE-AgNPs exhibited high cytotoxic activity against 5637 and MCF-7 cell lines compared to the cytotoxic activities of JOLE with IC50 of 13.09 µg/mL and 9.3 µg/mL, respectively. DISCUSSION: The silver nanoparticles formed by Jasminum officinale L. showed high cytotoxic activities against MCF-7 and 5637 cell lines and can be introduced as a new alternative cytotoxic medication.

Introduction

Nanotechnology is a progressive science of applying nanoparticles in different sectors of technology, it has revolutionized many sectors of technology, medicine and industry, particularly the pharmaceutical and energy industry, food safety and environmental sciences, among many others.1

The application of nanotechnology in medicine depends on the natural scale of biological phenomena to produce precise means of disease prevention, diagnosis and treatment.2

Formation of metal nanoparticles with optimum physical and chemical characters was the main goal of different research groups in the last few years. Formation of metal nanoparticles through chemical reactions, thermal decomposition or microwave-irradiation lead to the formation of toxic waste products and involves toxic chemicals; so biogenerations of metal nanoparticles through natural mechanisms using bacterial, fungal, or plant extracts are favorable methods to form safe clean and bio-friendly nanoparticles. Reduction of silver nitrate by plant extracts to form silver nanoparticles is a safe, clean, and rapid technique. The plant extract acts as a safe natural capping, reducing and stabilizing agent with no thermal or chemical hazards, many plant extracts were used for the formation of silver nanoparticles.3

Formation of nanoparticles may be a glimmer of hope for the production of vaccines and treatments that are inefficient and effective for many intractable viral epidemic diseases such as Covid-19.4

Jasminum officinale L. belongs to the family Oleaceae and known as true jasmine, common jasmine, or poet jasmine and is a species of flowering plant with very pleasant aroma.5 It is a well-known aromatic medicinal and industrial plant containing alkaloids, sesquiterpenes, secoiridoids and flavonoids.6,7 Jasminum officinale showed several pharmacological activities as antimicrobial, antiviral, wound healing promoter and antispasmodic agent,8–11 in addition to cytotoxic activities.12

Green synthesized silver nanoparticles differ in their biological activities according to the capping agent (plant extract) composition; silver nanoparticles (AgNPs) of Acalypha wilikesiana flowers exhibited potent cytotoxic activity against MCF-7 (breast carcinoma) and PC-3 (prostate carcinoma) cell lines, while the AgNPs of Caesalpinia gilliesii against MCF-7 showed moderate anticancer activity.13,14 Therefore; detection of plant chemical composition tentatively by HPLC-PDA/MS/MS can identify the possible major molecular structures that play a role in green nanoparticles formation as mentioned in our previous study on other Jasminum species (Jasminum sambac).15

In the present study, Jasminum officinale L. leaf extract (JOLE) was used for the biosynthesis of silver nanoparticles (AgNPs). The synthesized AgNPs using JOLE (JOLE-AgNPs) were characterized through UV-visible spectroscopy followed by X-ray diffraction (XRD), TEM (transmission electron microscopy), zeta potential and FTIR (Fourier transform infrared spectroscopy). JOLE and JOLE-AgNPs were examined for their cytotoxic activities by neutral red assay against two cell lines; breast (MCF-7) and bladder (5637) cancer cell lines. Investigation of JOLE secondary metabolites by HPLC-PDA/MS/MS was performed to evaluate the role of the plant constituents that affect the nanoparticles formation.

This study was designed to evaluate the ability of Jasminum officinale leaves extract to act as a reducing agent on AgNO3 to form ecofriendly, small particles, clean silver nanoparticles, and study the enhancement of the cytotoxic activity of the formed nanoparticles.

Materials and Methods

Preparation of Extract

Jasminum officinale L. leaves powder, prepared from the dried fine ground leaves, collected from Keram farms, El-Behaira Government, Egypt, and used for the biosynthesis of AgNPs. The plant was authenticated by Dr. Mohammed El Gebaly (consultant botanist-Orman Garden), voucher specimen (# 3.10.16.6) was kept at the Department of Pharmacognosy, Faculty of Pharmacy, Cairo University.

Powdered leaves (10 g) were mixed in 90 mL of distilled water and incubated at room temperature for 24 h. The extract was filtered and centrifuged for 40 min at 4000 rpm. The supernatant was used for AgNPs biosynthesis and stored at 4 °C for further use.

Identification of Extract Constituents

The aqueous extract of leaves of Jasminum officinale L. was used for HPLC-PDA-MS/MS. For MS analysis, LCQ-Duo ion trap having a Thermo Quest ESI source was used,16 Xcalibur software (Xcalibur™ 2.0.7, Thermo Scientific, Waltham, MA, USA) was used for system control. MS operating parameters in the negative ion mode were used.17

Synthesis of Silver Nanoparticles

AgNPs were synthesized according to the following protocol: 1 mM aqueous solution of silver nitrate (AgNO3) in dist. H2O was prepared and kept in a cool and dark place to be used for the synthesis of silver nanoparticles. 10 mL of the extract of leaves of JOLE into 90 mL of aqueous solution of 1 mM silver nitrate for reduction of Ag+ ions to nano silver particles in a molar concentration of (1.7 mg of silver nitrate: 1.2 mg extract) and incubated at room temperature in a dark place (for 24 h). The formation of a yellowish brown solution was the indication for the formation of silver nanoparticles.18 The formed solution was used directly for TEM, HR-TEM and UV quantifications then centrifugation at 4000 rpm for 30 minutes, followed by a series of washes with distilled water and filtration to obtain pure AgNPs. The pure AgNPs were used for FTIR, XRD, Zeta potential and cytotoxicity study.19–21

Characterization of Silver Nanoparticles

UV-Spectroscopy

The bioreduction of AgNPs was confirmed by subjecting diluted aliquots of the silver metallic NPs to UV-visible spectrophotometry (Model Shimadzu UV- 2450, Japan) in the range of 300–500 nm the UV-visible results were a confirmation tool for the formation of silver nanoparticles.22

Fourier Transform Infrared Spectroscopy (FTIR)

The different functional groups of the prepared nanomaterials in the range of 4000–400 cm−1 were measured by a Fourier transform infrared spectroscopy (FTIR) 6100 spectrometer (Jasco, Japan).

X-Ray Diffraction (XRD)

The XRD analysis was performed as a surface chemical analysis tool for characterization of metal nanoparticles.23 XRD was performed using a XPERT-PRO-PANalytical Powder Diffractometer (PANalytical B.V., Almelo, The Netherlands) using monochromatic radiation source Cu K α radiation (θ = 1.5406 Å) at a voltage of at 45 kV and a current of 30 mA at room temperature. The intensity data for the silver nano powder were operated over a 2θ range of 4.01°–79.99°.

Transmission Electron Microscope (TEM) and High Resolution TEM (HR-TEM)

The morphology of the particles (shape and dimensions) was examined by transmission electron microscope (TEM). (JEOL-JEM-1011, Japan) and high resolution electron microscope (HR-TEM) at 200 kV (JEOL-JEM-2100, Japan). Sample for TEM and HR-TEM analysis were prepared by placing 3 mL of the sample on the copper grid and kept for drying at room temperature for 15 min.

Zeta Potential and Dynamic Light Scattering (DLS)

Particle size, homogenousity of distribution and zeta potentials of nanoparticles were determined using Zeta sizer Nano ZN (Malvern Panalytical Ltd, United Kingdom). Before the measurements, dilution of an aliquot of nanoparticles with ultra purified water, then sonication for 15 min was performed.

Cytotoxicity Assay

MCF-7, 5637 and HaCaT cells were obtained from CLS Cell Lines Service (Eppelheim, Germany). Cells were cultured in RPMI 1640 medium (BioWhittaker, Lonza, Belgium) supplemented with 8% fetal bovine serum (Sigma Aldrich, Germany) and antibiotics (100 U/mL penicillin/100 µg/mL streptomycin; Sigma Aldrich, Germany) at 95% humidity, 5% CO2 and 37.5 ◦C. MCF-7, 5367 and HaCaT cells were sub-cultured twice a week and regularly tested for mycoplasma contamination. Cell viability (cytotoxicity) of the test samples was investigated on the cell lines using the neutral red uptake (NRU) assay.

Statistical Analysis

Calculations of the arithmetic means and the standard deviation of all tests were carried out using the software program Microsoft Excel 2007. Statistical analysis was performed using GraphPad Prism version 5.01. One-way ANOVA, followed by the Tukey-posthoc-test, was used to determine the statistical significance in comparison to the reference standard. All data are presented as mean ± S.D. values of three independent determinations. The p-value<0.05 was statistically significant.

Nanoparticles Characterization

Physical Observation

The synthesis was investigated at initial silver ion concentration of 1 mM. In a typical experiment, 90 mL of 1 mM silver nitrate was reacted with 10 mL of JOLE. After 4 h, the formation of Ag nanoparticles was observed and detected by the appearance of dark brown coloration.

UV-spectroscopy is a simple, selective and accurate technique for monitoring the synthesis and stability of AgNPs. AgNPs exhibit particular and unique optical characteristics, that allow them to powerfully interact with certain light wavelengths. The free electrons give rise to a surface plasmon resonance (SPR) absorption band due to the collective oscillation of electrons of AgNPs. The absorption of AgNPs depends on the chemical surroundings, particle's dimensions and particle size.

The appearance of the new broad absorption peak at 363 nm after 4 h indicated that the formation of AgNPs started within 4 h after JOLE interact with Ag+  ions. The formed peak at  λmax = 363 nm is evidence on the formation of  aggregated and mostly spherical NPs, so UV spectroscopy  is an appropriate technique to inform the formation of AgNPs.24 (Figure 2).

Figure 2

UV absorbance spectrum of JOLE(Jasminum officinaleleaves extract) and JOLE-AgNPs(Jasminum officinale leaves extract mediated silver nanoparticles).

The FTIR spectroscopy analysis was performed to identify the phytoconstituents  possible biomolecules of JOLE that are responsible for the synthesis of AgNPs. The peaks near 3390, 2921 and 1618 cm−1 (Figure 3A) could be due to the O-H, aliphatic C-H and C=O stretching vibration of secoiridoids/flavonoids/phenolic acids. The peak at 1410 cm−1 corresponds to polyphenols and affirm the existence of an aromatic ring, while the signals at 1044 cm-1 were assigned for the C-O-C and secondary OH groups of JOLE. There was a deviation of a signal detected for AgNPs at 3390 and 1618 cm−1 (Figure 3B), it suggests that the O-H and C=O groups were responsible for the reduction of AgNO3 and formation of AgNPs.

TEM and HR-TEM

The formed JOLE-AgNPs after 48 h were predominantly of spherical shape, with an average size of 9.22 nm (Figure 4).

Figure 4

(A, B) TEM images, (C, D) HR-TEM of JOLE-AgNPs (Jasminum officinale leaves extract mediated silver nanoparticles) at different scales.

Dynamic light scattering measures the hydrodynamic size and the ligand shell of the formed nanoparticles, the size is different from the TEM and HR-TEM where only the metallic core is measured. DLS of JOLE-AgNPs is 87.6 ± 2.11 nm and homogenous distribution of the formed nanoparticles with (polydispersity index: 0.312±0.032). The zeta potential is a measure of nanoparticles stability through measuring of the surface charge potential in aqueous suspensions. Zeta potential values of AgNPs were measured to be −25.5±0.7 mV (Figure 5). The produced nanoparticles had a negative charge on their surface, which indicates a high stability.25

The diffractogram of JOLE-AgNPs, the obtained diffraction silver nano peaks at 38.60°, 44.16°, 64.52° and 77.34° are respectively assigned to (111), (200), (220) and (311) planes (Figure 6), consistent with the face cubic center (fcc) nature of silver nanoparticles. This corresponds to the Joint Committee on Powder Diffraction Standards-International Center for Diffraction Data No. 64–2663, indicating the crystalline nature of the biosynthesized silver nanoparticles as confirmed by the corresponding peaks with respect to Bragg’s model of diffraction. The results are consistent with the reference data of silver nanoparticle's formation.26

Cytotoxicity

The bladder cancer (5637) and breast cancer (MCF-7) cell lines, were exposed to (JOLE) and (JOLE-AgNPs), and the cytotoxicity determined using the NRU assay were examined for their cytotoxic activities by neutral red assay at the concentrations of 0–280 μg/μL for 24 h towards two cell lines; bladder cancer (5637) and breast cancer (MCF-7) using etoposide reference standard and compared to normal keratinocyte cells (HaCaT). NRU results have shown that AgNPs could significantly induce cytotoxicity in bladder cancer (5637) and breast cancer (MCF-7) cell lines, in a dose-dependent manner. Data analysis of the cytotoxicity assay has shown that the IC50 values of (JOLE-AgNPs) against the 5637 and MCF-7 cell lines and HaCaT, were 13.1 μg/μL, 9.3 μg/μL and 183.8 μg/μL; respectively after the incubation periods (P<0.05). Whereas the IC50 values of JOLE shows 28.8 μg/μL, 40.0 μg/μL and 477.4 μg/μL against the 5637 and MCF-7 cancer cell lines and HaCaT, respectively. after the incubation time. (Figure 7). The cytotoxicity results indicated the improvement of the cytotoxicity characteristics of leaves extract of Jasminum officinale upon formation of its corresponding AgNPs, especially towards the 5637, and MCF-7 cancer cell lines with very low toxicity towards normal cell line HaCaT.

Conclusion

Medicinal plants, namely, aqueous extracts of fresh leaves of Jasminum officinale L. can be used as bioreduction agents to produce clean, inexpensive, ecofriendly silver nanoparticles and a safe method that has not used any toxic substance and consequently does not have side effects. Nanoparticles formation was observed by the color change of J. officinale extract into a brownish-yellow. Color changes that occur indicate that AgNO3 was reduced and Ag nanoparticles have been formed. HPLC-PDA/MS/MS tentatively identified 51 compounds of different classes; secoiridoid glycosides as a major class of compounds, phenolic acids and flavonoids. Formation of silver nanoparticles were proved physically through color change of the extract solution to a brownish-yellow color. UV spectra showed a broad absorption peak at λmax = 363 nm, which represents spherical and aggregated NPs, The biosynthesized AgNPs were predominantly spherical in shape with an average size of 9.22 nm by TEM. The face cubic center (fcc) nature of silver nanoparticles was proved by XRD diffractogram. Zeta potential values of AgNPs were measured −25.5±0.7 silver nanoparticles proved the stability of these silver nanoparticles with JOLE-AgNPs exhibiting high cytotoxic activity towards 5637 and MCF-7 cell lines compared to the cytotoxic activities of JOLE with an IC50 of 13.09 µg/mL and 9.3 µg/mL, respectively, The formed silver nanoparticles showed high cytotoxic activities and can be introduced as a new alternative cytotoxic medication.
