摘　　要：试验旨在研究食药同源真菌发酵甘草对其活性成分含量及抗氧化性的影响。选取糙皮侧耳(Pleurotus ostreatus)HXS-M1发酵中药甘草,检测发酵前后甘草苷、甘草素、甘草酸和甘草次酸含量及ABTS~+清除率和DPPH·清除率的变化。结果表明:糙皮侧耳HXS-M1发酵前后甘草活性成分含量有极显著差异(P<0.01),发酵后甘草苷成分消失,甘草酸降低了59.41%,甘草素含量提高了270.29%,甘草次酸含量提高了390.23%;发酵后ABTS~+清除率极显著提高102.18%(P<0.01),DPPH·清除率极显著提高215.30%(P<0.01)。糙皮侧耳HXS-M1发酵甘草能够促进苷类物质转化为苷元,有利于提高甘草的生物利用度和药效。This study investigated the effects of food-medicine homologous fungi fermenting liquorice on the content of active components and antioxidant properties.Pleurotus ostreatus HXS-M1 was used to ferment liquorice,and the changes of liquiritin,liquiritigenin,glycyrrhizic acid and glycyrrhetinic acid content,the scavenging rate of ABTS+and DPPH·free radical before and after fermentation were detected.The results showed that the contents of active components in liquorice was sig-nificantly different before and after fermentation(P<0.01).Afeter fermentation,liquiritin disappeared,the content of glycyrrhizic acid was decreased by 59.41%,the contents of liquiritigenin and glycyrrhetinic acid were increased by 270.29%,390.23%;the ABTS+and DPPH·radical scavenging rate were significantly increased by 102.18%and 215.30%(P<0.01).Fermentation of liquorice by Pleurotus ostreatus HXS-M1 can promote the conversion of glycosides into aglycones,which was beneficial to improve the bioavailability and efficacy of liquorice.
