Four new lupane triterpenoid saponins, along with one known lupane and eight hederagenin saponins, were isolated from the EtOH extract of the buds of Lonicera similis Hemsl. The structures of the new compounds were established as 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl 23-hydroxybetulinic acid 28-O-β-D-glucopyranosyl ester (lonisimilioside A, 1), 3-O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranosyl
从拟南芥(Lonicera similis Hemsl)芽的EtOH提取物中分离出四种新的三聚戊二烯三萜皂苷,以及一种已知的三聚戊二烯和八种类二十碳皂苷元皂苷。被确立为3-新化合物的结构ø - β -D-吡喃葡萄糖基- (1→2) - β -D-吡喃葡萄糖23羟基白桦酸28- ö - β -D-吡喃葡萄糖酯(lonisimilioside A,1) ,3- ø - β -D-吡喃葡萄糖基- (1→2) - β -D-吡喃葡萄糖23羟基白桦酸28- ö - β -D-吡喃葡萄糖基- (1→6) - β -D-吡喃葡萄糖酯(lonisimilioside B,2),3- ø - β -D-吡喃葡萄糖基- (1→2) - β -D-吡喃葡萄糖桦木酸28- ö - β -D-吡喃葡萄糖基- (1→6) - β -D-吡喃葡萄糖酯(lonisimilioside C,3)和3- ø - β -D-吡喃葡萄糖基-
