Objective. The aim of study was to determine the in vivo antioxidant activity of newly formulated O/W cream of methanolic extract of Cassia tora L. leaves. Methods. Oil in water (O/W) creams (0.05%, 0.1%, and 0.2%), cream base, methanolic extract of C. tora L. leaves (CTM), and standard (0.05% tretinoin cream) were screened for in vivo antioxidant activity. The ultraviolet- (UV-) B-induced rats were treated with different standard, O/W creams, cream base, and methanolic extract of Cassia tora L. leaves (CTM). The parameters like lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) levels were assessed. Results. The result of acute dermal toxicity shows that the creams were safe up to 2000 mg/kg (topically). Exposure of ultraviolet light of medium wave (UV-B light) decreased the level of GSH, CAT, and SOD and increased the LPO level. Concluding Remarks. We conclude that topical O/W creams of C. tora L. prevent the oxidative stress induced in rats by exposure to UV-B light by virtue of its in vivo antioxidant property, and these findings help to understand the mechanism of the antipsoriatic activity of O/W creams of C. tora L. in UV-B-induced psoriasis in the rat.
