Studies on the Chemical Constituents and Antioxidant Activities of Ergosterol from Lenzites betulinus
摘要
Abstract
The chemical constituents and antioxidant activity of the fruiting bodies of Lenzites betulinus were studied.Six malsterols compounds steroids were isolated from the methanol extract of L.betulinus by various column chromatography techniques.The structures of the isolated compounds were identified by modern spectro-scopic analysis techniques,which are(22E,24R)-ergosta-7,22-dien-3β-ol(1),5α,8α-epidioxy-(22E,24R)-er-gosta-6,22-dien-3β-ol(2),ergosta-7,22-diene-6β-methanoxy-3β,5α-diol(3),(22E,24R)-ergosta-7,22-di-en-3β,5α,6β-triol(4),3β,5α-dihydroxy-(22E,24R)-ergosta-7,22-dien-6-one(5),3β,5α,9α-trihydroxyer-gosta-7,22-dien-6-one(6).Among them,compounds 3,5 and 6 were first report from L.betulinus.The antiox-idant activity of the above compounds was evaluated by using the DPPH free radical scavenging model.The res-ults showed that the scavenging rate of DPPH free radicals was less than 10％,when the concentration of the com-pounds was 400 μg/mL.Although the antioxidant activity couldn't be comprehensively evaluated,it still had cer-tain guiding significance.In this study,the chemical constituents of L.betulinus were studied to provide a refer-ence for further development and utilization of its resources.关键词
