Cissus quadrangularis L. is a member of succulent climber of family Vitaceae and it is also called as bone setter because of its bone healing property. The present study focused to assess the in vitro antioxidant and in vivo anti-inflammatory activity of the plant stem extracts in different solvents namely petroleum ether, chloroform, ethyl acetate and methanol. Among all these extracts; ethyl extract showed highest phenolic and flavonoid content (19.35±0.29mg GA/g, 8.68±0.06 RE/g dry wt. respectively). In DPPH free radical scavenging assay all mentioned extracts exhibited free radical scavenging activity but the highest free radical scavenging activity was showed by ethyl acetate extract in increasing dose dependent manner. On the basis of highest phenolic, flavonoid content and free radical scavenging activity ethyl acetate extract was selected for anti- inflammatory activity. The anti-inflammatory activity of Cissus quadrangularis Lin. was investigated in carageenan induced inflammation in Wistar albino rats. Two different doses 250mg/kg and 500mg/kg were administered to the animals. The results showed that both doses had significant reduction in inflammatory condition but dose 500mg/kg showed maximum inflammatory reduction on comparing with control and standard treated groups.

Seeds of Camellia oleifera are used for edible oil extraction, but the defatted seeds are always discarded. In this study, saponin was separated from the seeds after oil extraction by hexane and 70% aqueous methanol, purified by macro-reticular resin AB-8 and crystallized with 80% aqueous ethanol. Its structure was identified by MS, IR, 1H NMR and 13C NMR analysis. The DPPH radical scavenging activity was determined. Carrageenan-induced paw oedema in rats and Croton-oil induced ear inflammation in mice were tested for its anti-inflammatory ability. The results show the saponin has significant anti-inflammatory effects and free radical scavenging activity.
