| 1 | Evaluation of in vitro antioxidant and apoptotic activities of Cyperus rotundus显示文摘Objective:To evaluate in vitro antioxidant and apoptotic activities of Crperus rotundas(C.rotundus).Methods:The phytochemical study and the antioxidant activities of both methanol and aqueous extracts from C.rotundus aerial part were determined.In addition,these extracts were also investigated for their cytotoxic and apoptotic activities.The major compound of the methanol extract was isolated.Both metlianol and aqueous extracts(300,150,and 50μg/mL)were evaluated for their antioxidant activity by the xanthine/xanthine oxidase assay system.However,16,8,and 4 mg/mL of each extract were tested to investigate their OH.formation scavenging potential.Aqueous extract(800,400.and 200μg/mL)and melhunol extract(350,175,and 88μg/mL)were tested against lipid peroxidation,induced by 75μM H_2O_2,The cytotoxicity(by MTT assay)and cell DNA fragmentation of both extracts were evaluated Inwards K562 and L1210 cell lines.The major compound was obtained from the butanol fraction of methanol extract and its structure was determined by KMN spectroscopic analysis.Results:The methanol and aqueous extracts showed respectively,88%and 19%inhibition of xanthine oxidase activity.Vet.the same extracts inhibited lipid peroxidation by 61.5%and 42.0%.respectively.Roth extracts inhibited OH.formation by 27.1%and 25.3%,respectively.Only methanol cxtract induced DNA degradation.Orientin was determined as the major compound isolated from the butanol fraction of metlianol extract.Conclusions:It appears that C.rotundus extracts exhibit a potential use as a natural antioxidant and an apoptosis inducer. | Kilani-Jaziri Soumaya Ghedira Zied Nasr Nouha Krifa Mounira Ghedira Kamel Franca Dijoux Marie Genviève Ghedira Chekir Leila | 2014 | Asian Pacific Journal of Tropical Medicine2014，7，2： | 2 |
