BACKGROUND: The present study was planned to investigate the phytochemical, antioxidant, antinociceptive, anticoagulant and cytotoxic activities of the Jacquemontia tamnifolia (L.) Griseb leaf methanol extract (MExJT) in the laboratory using both in vitro and in vivo methods. METHODS: Phytochemical values, namely, total phenolic and flavonoid contents, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect and FeCl3 reducing power effects, were studied by established methods. In vivo antinociceptive activity was performed by acidic acid-induced writhing test and formalin-induced pain test on Swiss albino mice at doses of 125, 250 and 500 mg/kg body weight. The clot lysis and brine shrimp lethality bioassay in vitro were used to evaluate the thrombolytic and cytotoxic activities of the plant extract, respectively. RESULTS: Phytochemical screening illustrates the presence of tannins, saponins, flavonoids, gums and carbohydrates, steroids, alkaloids and reducing sugars in the extract. The results showed the total phenolic content (146.33 g gallic acid equivalents/100 g extract) and total flavonoid content (133.33 g quercetin/100 g). Significant (p<0.05) IC50 values compared to respective standards were recorded in DPPH radical scavenging (289.5 μg/mL) and FeCl3 reduction (245.2 μg/mL). The antinociceptive effect was evaluated in the acetic acid-induced writhing test and formalin-induced pain models in Swiss albino mice with doses of 125, 250 and 500 mg/kg body weight. Significant (p<0.05) inhibition (72.87±2.73%) of writhing response compared to diclofenac sodium was achieved by 500 mg/kg body weight. The extract also significantly inhibited the licking response in both the early phase (51.59±1.57%, p<0.05) and the late phase (64.82±1.87%, p<0.05) in the formalin-induced writhing test. MExJT also showed (38.10±1.79%) clot lytic activity in the thrombolytic test and cytotoxicity with an LC50 value of 31.70 μg/mL in the brine shrimp lethality bioassay. CONCLUSIONS: The plant is a potential source of antioxidants and might have one or more secondary metabolite(s) with central and peripheral analgesic activity. The results also demonstrate that MExJT has moderate thrombolytic and lower cytotoxic properties that may warrant further exploration.
