摘　　要：Objective: To ascertain anti-fatigue constituents and mechanisms of Herpetospermum caudigerum. Methods: The 80% ethanol extracts of Herpetospermum caudigerum were partitioned with chloroform, ethyl acetate and n-butanol, respectively. Male Kunming mice were divided into 13 groups with 16 mice in each group: a control group fed with water, 9 groups treated with 3 fractions of Herpetospermum caudigerum(chloroform fraction, ethyl acetate fraction and n-butanol fraction) at dose of 80, 160 and 320 mg/kg for the low-dose group, medium-dose group and high-dose group, 3 herpetrione(HPE) treated groups fed with HPE at dose of 15, 30, and 60 mg/kg for the low-dose group, medium-dose group and high-dose group. All animals were treated once per day for 30 days. Anti-fatigue activity was assessed through the forced swimming test and serum biochemical parameters including blood lactic acid(BLA), blood urea nitrogen(BUN), malondialdehyde(MDA), hepatic glycogen(HG), lactic dehydrogenase(LDH), superoxide dismutase(SOD) and glutathione peroxidase(GPx) determined following the recommended procedures provided by the commercial kits. Results: Compared with the control group, the lignans extract(ethyl acetate fraction) of Herpetospermum caudigerum and HPE could significantly prolonged the exhaustive swimming time(P<0.05 or P<0.01), and also increased the HG levels(P<0.05 or P<0.01) and the activities of antioxidant enzymes(SOD, GPx and LDH, P<0.05 or P<0.01); BLA and MDA levels were decreased considerably in lignans extract and HPE treated groups(P<0.05 or P<0.01). HPE also could significantly decrease the BUN contents compared with the control group(P<0.05). The chloroform and n-butanol fraction showed no effect on swimming time and biochemical parameters. Conclusions: The lignans extract had antifatigue activities and HPE may be partly responsible for the anti-fatigue effects of Herpetospermum caudigerum. The possible mechanisms of anti-fatigue activity were related to the decrease of BUN and BLA, the increase of the HG storage andObjective: To ascertain anti-fatigue constituents and mechanisms of Herpetospermum caudigerum.
