Data of antihyperlipidaemic activity for methanolic extract of Tagetes patula Linn. flower head along with piperine, as bioavailability enhancer.

The data present in this article is associated with influence of piperine (secondary metabolite) on the antihyperlipidemic and antioxidant activity of methanolic extract of Tagetes patula (METP). METP was evaluated for antihyperlipidemic and antioxidant potential. Phytoconstituents of METP were identified using gas chromatography linked with a mass spectrometer. in vivo antihyperlipidemic activity of METP at the dose of 200 and 400 mg/kg b. wt. and 200 and 400 mg/kg b. wt. along with piperine (20 mg/kg b. wt.) were evaluated by Propylthiouracil induced and Triton X-100 induced hyperlipidemia in rats. Propylthiouracil significantly increased the serum TC (p<0.01), TG (p<0.01), LDL (p<0.01) and VLDL (p<0.01) levels and induction of HDL (p<0.01) at a dose of 400 mg/kg b. wt. along with piperine. Triton X-100 at a single dose of i.p increased lipid levels within 48 h. Increased lipid levels were significantly reduced TC (p<0.01), TG (p<0.01), LDL (p<0.05) and VLDL (p<0.05) by METP at doses of 200 and 400 mg/kg b. wt. along with piperine. Current data were also supported by histological study of livers, Cord pattern of hepatocytes, few periportal lymphocytes in focal area observed in hyperlipidemic rats and hepatocyte, periportal and centrilobular region of liver appear normal in treated group. METP along with piperine (capability to enhance bioavailability and has a property of increasing oral absorption of drugs) showed promising antioxidant and antihyperlipidemic activity which suggests the further use of Tagetes patula extract for the management of hyperlipidemia and atherosclerosis.

Specifications table

Was performed by using female mice followed by OECD guidelines 425. Hyperlipidaemia was induced with propylthiouracil of 10 mg kg- b. wt. dosage and 0.01% PTU in drinking water for 7 days.

Value of the data

The methods and data can be used to study Tagetes patula for its antihyperlipidaemic property studied in detail.

Comparison of antihyperlipidaemic activity data of METP (200 and 400 mg/kg bd.wt.) alone and along with piperine (20 mg/kg bd.wt) as penetration enhancer also gives reference for researchers for formulation studies.

GC–MS data and in vitro antioxidant activity data of METP also provide valuable reference to compare secondary metabolite and their action as antihyperlipidaemic activity. Furthermore Nutritional ingestion of this plant species will put in innovative scope in the managing of hyperlipidemia and other metabolic disorders.

Data

The present data focuses on antihyperlipidemic capability of Tagetes patula Linn. Tagetes patula Linn. (French marigold) belongs to the family Asteraceae is widely known for its phytochemical and medicinal properties. The data on chemical composition of methanolic extract Tagetes patula Linn was done by gas chromatography and mass spectrometry are shown in Fig. 1 and Table 1. Information regarding changes in lipid profile (TC, TG, LDL, VLDL and HDL) for PUC and triton induced antihyperlipidemic are presented in Table 2 (Fig. 2) and Table 3 (Fig. 3) respectively. Data regarding histological changes of rat hepatocytes of liver are shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10. The present investigation helps in finding the influence of piperine on antihyperlipidemic activity of Tagetes patula.

Identification of phytochemical constituents using gas chromatography

GC–MS analysis was carried out by Agilent 6890 series GC–MS instrument coupled with mass spectroscopy as a detector. The temperature was adjusted to −30 °C to 280/300 °C. The HP-5MS column with dimensions 30 m ×0.32 mm × 0.25 µm was used for analysis. The oven temperature was adjusted to 35 °C and hold time 5 min, ramp 10 °C / min up to 220 °C. Column flow is 1.2 mL. The inlet temperature was kept at 250 °C and the source temperature of 230 °C and MS Quard temperature of 150 °C (Table 1).

in vitro antioxidant assays

The scavenging ability of free radicals as hydroxyl and NO˙ was measured by the method of Kunchandy and Rao (1990) [3], [4]. Data outcome is shown in Table 4.
