ABSTRACT
Snake bites are a serious health hazard occurs throughout the world especially in tropical countries like India. Anti-Snake Venom Serum is the only remedy available to treat snake bite victims successfully till date. Infusion of ASV may lead to adverse reactions ranging from severe itching of the skin, hives to potentially serious allergic reactions. Considering all above difficulties research workers all over the world is constantly in search of a cheap and readily available easy formulate remedy for treating snake bite victims. In present study aqueous extract of Rauvolfia serpentina root was checked for the antidote properties against Naja naja venom by in vitro and in vivo methods. Various in vitro neutralization tests like Acetyl cholinesterase, Protease and ATPase activity of Naja naja venom were carried out and the root extract was neutralized all the toxic effects induced by the venom. The in vivo assessment of venom lethality (LD50) of Naja naja venom was found to be 0.301 µg. The aqueous root extract was effectively neutralized the venom lethality and effective dose (ED50) was found to be 12.88 mg/ 3LD50 of Naja naja venom. LC-MS analysis from root extract of Rauvolfia serpentina was done for confirmation of the bioactive compounds.
ABSTRACT
OBJECTIVES: Snakebites are a significant and severe global health problem. Till date, anti-snake venom serum is the only beneficial remedy existing on treating the snakebite victims. As antivenom was reported to induce early or late adverse reactions to human beings, snake venom neutralizing potential for Cyclea peltata root extract was tested for the present research by ex vivo and in vivo approaches on Naja naja toxin. MATERIALS AND METHODS: Ex vivo evaluation of venom toxicity and neutralization assays was carried out. The root extracts from C. peltata were used to evaluate the Ex vivo neutralization tests such as acetylcholinesterase, protease, direct hemolysis assay, phospholipase activity, and procoagulant activity. Gas chromatography-mass spectrometry (GC-MS) analysis from root extracts of C. peltata was done to investigate the bioactive compounds. RESULTS: The in vivo calculation of venom toxicity (LD50) of N. naja venom remained to be 0.301 µg. C. peltata root extracts were efficiently deactivated the venom lethality, and effective dose (ED50) remained to be 7.24 mg/3LD50 of N. naja venom. C. peltata root extract was found effective in counteracting all the lethal effects of venom. GC-MS analysis of the plant extract revealed the presence of antivenom compounds such as tetradecanoic and octadecadienoic acid which have neutralizing properties on N. naja venom. CONCLUSION: The result from the ex vivo and in vivo analysis indicates that C. peltata plant root extract possesses significant compounds such as tetradecanoic acid hexadecanoic acid, heptadecanoic acid, and octadecadienoic acid which can counteract the toxins present in N. naja.
