This study evaluates the in vitro anti-snake venom potential of Peristrophe bivalvis (PB) extracts against Naja kaouthia (NK) and Trimeresurus albolabris (TA) venoms, including inhibition of cytotoxic effects and enzymatic activities, and the binding-precipitation of extracts and venom proteins analysis. In addition, the antioxidant, cytotoxic and in vivo acute oral toxic activities of PB extracts are also reported. The in vitro cytotoxic and enzymatic analysis reveals that the ethanol extracts of stems and leaves of PB showed good anti-snake venom activity against NK and TA venoms. In addition, the antioxidant result indicated that only the ethanol extract of leaves exhibited weak DPPH radical-scavenging activity. The ethanol whole-plant extract of PB also showed no cytotoxicity against four cell lines. Moreover, the in vivo acute oral toxicity result of the ethanol whole-plant extract showed that all treated rats did not exhibit abnormal toxic signs or deaths.
