摘要
利用各种现代色谱方法从掌叶梁王茶Nothopanax delavayi茎皮70%乙醇提取物中分离得到11个化合物,通过波谱技术和理化性质鉴定它们的结构为三对节酸3-O-α-L-吡喃阿拉伯糖-28-O-β-D-吡喃葡萄糖酯苷(1),三对节酸3-O-α-L-吡喃阿拉伯糖-28-O-α-L-吡喃鼠李糖-(1→4)-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(2),三对节酸(3),三对节酸3-O-α-L-吡喃阿拉伯糖苷(4),三对节酸3-O-β-(2',4'-O-二乙酰基)-D-吡喃木糖-28-O-α-L-吡喃鼠李糖-(1→4)-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(5),三对节酸3-O-α-(4'-O-乙酰基)-L-吡喃阿拉伯糖-28-O-α-L-吡喃鼠李糖-(1→4)-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(6),三对节酸3-O-α-(2'-O-乙酰基)-L-吡喃阿拉伯糖-28-O-α-L-吡喃鼠李糖-(1→4)-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(7),三对节酸3-O-β-D-吡喃木糖-28-O-α-L-吡喃鼠李糖-(1→4)-β-D-吡喃葡萄糖-(1→6)-β-D-吡喃葡萄糖酯苷(8),原儿茶酸(9),咖啡酸乙酯(10),咖啡酸酐(11)。其中化合物3~4,9~11为首次从梁王茶属植物中分离得到,化合物5~8为首次从该植物中分离得到。
Eleven compounds were isolated and purified from the barks extract of Nothopanax delavayi and their structures were identified as serratagenic acid-3-O-α-L-arabinopyranosyl-28-O-β-D-glucopyranosyl ester( 1),serratagenic acid-3-O-α-L-arabinopyranosyl-28-O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl] ester(2),serratagenic acid(3),serratagenic acid-3-O-α-L-arabinopyranoside(4),serratagenic acid-3-O-β-(2',4'-O-diacetyl)-D-xylopyranosyl-28-O-[α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl]ester(5),serratagenic acid-3-O-α-(4'-O-acetyl)-L-arabino pyranosyl-28-O-[-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl]ester(6),serratagenic acid-3-O-α-(2'-Oacetyl)-L-arabinopyranosyl-28-O-[-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl]ester(7),serratagenic acid-3-O-β-D-xylopyranosyl-28-O-[-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl] ester(8),protocatechuic acid(9),ethyl caffeate(10) and caffeic anhydride(11) by physicochemical properties and spectroscopic data analysis.Among them,compounds 3-4 and 9-11 were firstly isolated from the genus Nothopanax,and compounds 5-8 were isolated from this plant for the first time.
