从丝瓜(Luffa cylinderica Roem)叶中分得三种成分,经光谱和化学方法确定其结构为21β-羟基丝石竹皂甙元(L-2),2α-羟基常春藤皂甙元-3-O-β-D-吡喃葡萄糖甙(L-8)和21β-羟基常春藤皂甙元-3-O-β-D-吡喃葡萄糖甙(L-10)。L-2和L-10为新的天然产物,依次命名为丝瓜素A(lucyin A)和丝瓜皂甙N(lucyoside N)。
Three components were isolated from leaves of Luffa cylinderica Roem. The structure was confirmed by spectroscopic and chemical methods. The structure was 21β-hydroxyl-saponin (L-2), 2α-hydroxyl-isophytosan saponin-3-O-β. -D-Glucopyranoside (L-8) and 21β-Hydroxy-Ivy Saponins-3-O-β-D-glucopyranoside (L-10). L-2 and L-10 are new natural products, named lucine A and lucyoside N, respectively.
