摘要/Abstract

摘要：

对桑黄的抑制α-葡萄糖苷酶活性成分进行筛选和优化提取,并对提取物中的酚类、黄酮和萜类物质进行了靶向鉴定。以α-葡萄糖苷酶抑制活性和总黄酮含量为评价指标对提取工艺参数进行了优化,通过UHPLC-Q-Exactive Orbitrap MS对提取物的成分进行鉴定。结果表明,桑黄60%乙醇体积分数提取物具有较好的α-葡萄糖苷酶抑制活性,优化提取的工艺条件是乙醇体积分数60%,提取温度80 ℃,提取时间3 h,料液比1:30,提取2次,黄酮提取率达到159.3 mg·g^-1。液质联用共鉴定出45种成分,其中酚类物质种类最多。通过优化工艺得到含量较高的具有较强α-葡萄糖苷酶抑制活性的提取物,液质联用靶向分析表明该提取物中含有丰富的多酚类物质。

关键词: 桑黄, α-葡萄糖苷酶, 提取, 成分鉴定

Abstract:

To screen and extract the α-glucosidase-inhibitory components in Phellinus baumii,and to identify the constituents in the extracts, the four technological parameters were optimized by α-glucosidase-inhibitory rate and total flavonoid content, and the constituents were identified by UHPLC-Q-Exactive Orbitrap MS. The extracts by 60% ethanol exhibited significant inhibitory activity. The optimized extraction by orthogonal test were achieved using 60% of ethanol volume fraction at 80 ℃ for 3 h with a solid-to-liquid ratio of 1:30 for two times, whose flavonoid extraction ratio reached 159.3 mg·g^-1. Forty five components were identified by LC-MS, among which phenolic substances were in the majority. The extracts with high flavonoids content and high α-glucosidase-inhibitory activity was obtained by optimized technology, containing abundant polyphenols.

Key words: Phellinus baumii, α-glucosidase, extract, component identification
