Three new triterpenoid saponins named silenosides A-C (1-3) were obtained from the roots of Silene vulgaris. Their structures were elucidated by spectral and chemical methods as beta-D-galactopyranosyl(1-->2)-beta-D-glucuronopyranosyl-3beta- hydrox y-23-oxoolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl(1-->3)-beta-D-xylopyranosyl(1-->4)-alpha-L- rhamnopyranosyl(1-->2)-beta-D-fucopyranoside; 3-O-beta-D-galactopyranosyl(1-->2)-beta-D-glucuronopyranosyl-3beta , 16alpha-dihydroxy-23-oxoolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl(1-->4)-[beta-D-glucopyranosyl(1-->2)]-alpha -L-rhamnopyranosyl(1-->2)-beta-D-fucopyranoside; and 3-O-alpha-L-arabinopyranosyl(1-->3)-[beta-D-galactopyranosyl(1-->2 )]- beta-D-glucuronopyranosyl-3beta, 16alpha-dihydroxy-23-oxoolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl(1-->4)-[beta-D-glucopyranosyl(1-->2)]-alpha -L-rhamnopyranosyl(1-->2)-beta-D-fucopyranoside, respectively.
从普通蝇子草的根中获得了三种新的三萜皂苷，命名为蝇子草苷A - C（1 - 3）。通过光谱和化学方法确定它们的结构分别为β - D - 吡喃半乳糖基（1→2）-β - D - 吡喃葡糖醛酸基-3β - 羟基-23 - 氧代齐墩果-12 - 烯-28 - 酸28 - O - β - D - 吡喃木糖基（1→3）-β - D - 吡喃木糖基（1→4）-α - L - 鼠李吡喃糖基（1→2）-β - D - 岩藻吡喃糖苷；3 - O - β - D - 吡喃半乳糖基（1→2）-β - D - 吡喃葡糖醛酸基-3β，16α - 二羟基-23 - 氧代齐墩果-12 - 烯-28 - 酸28 - O - β - D - 吡喃木糖基（1→4）-[β - D - 吡喃葡萄糖基（1→2）]-α - L - 鼠李吡喃糖基（1→2）-β - D - 岩藻吡喃糖苷；以及3 - O - α - L - 阿拉伯吡喃糖基（1→3）-[β - D - 吡喃半乳糖基（1→2）]-β - D - 吡喃葡糖醛酸基-3β，16α - 二羟基-23 - 氧代齐墩果-12 - 烯-28 - 酸28 - O - β - D - 吡喃木糖基（1→4）-[β - D - 吡喃葡萄糖基（1→2）]-α - L - 鼠李吡喃糖基（1→2）-β - D - 岩藻吡喃糖苷。
