南山茶籽中4个多酚化合物的鉴定
Identification of 4 polyphenolics from seeds extracts of Camellia semiserrata Chi.
摘要
Abstract
To comprehensively develop and utilize Camellia semiserrata resources,compounds of ethanol extract of Camellia semiserrata Chi.cake were separated and identified.Five purified compounds were achieved by HPLC preparation from 4 fractions including ⅩⅦ,ⅩⅩⅥ,ⅩⅩⅧ and ⅩⅩⅩⅣ by ethyl acetate extraction and silica gel column chromatography.The analysis of compound 4 has been reported in another paper.Four compounds were identified as protocatechoic acid (1),apigenin-6-C-β-D-glucopyranoside (2),kaempferol-3-O-[α-L-rhamnopyranosyl-(1-3)-2,4-di-O-acety-α-L-rhamnopyranosyl-(1-6)]-β-D-glucopyranoside (3),and kaempferol-3-O-[α-L-rhamnopyranosyl-(1-3)-2,4-di-O-acet yl-α-L-rhamnopyranosyl-(1-6)]-β-D-glucopyranoside (5) by spectral analysis,among which,compounds 3 was the first time reported in the Camellia genus,and compounds 5 was firstly reported in Camellia semiserrata Chi.,The structures were analyzed in detail for compounds 2 and 5,which were isolated from Camellia semiserrata Chi.for the first time,and compound 3 extracted from the camellia genus for the first time.For these three compounds 1H and 13C chemical shifts were fully affiliated.关键词
