Two new saponins have been isolated from the aerial parts of Herniaria fontanesii. Their structures were established as 28-O-[alpha-L-rhamnopyranosyl-(1-->2-[(alpha-L- rhamnopyranosyl)-(1-->3)-]-(beta-D-4-acetoxyfucopyranosyl] ester of 3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl uronic]-2 beta-3 beta-16-alpha-trihydroxy-olean-12-ene-23, 28-dioic acid and 28-omicron-[alpha-L-rhamnopyranosyl-(1-->2-[alpha-L-rhamnopyranosyl (1-->3)]-(beta-D-fucopyranosyl] ester of 3-omicron-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranosyl uronic]-2 beta-3 beta-16-alpha-trihydroxy-olean-12-ene-23, 28 dioic acid.
从Fontanes氏卷耳的地上部分分离出了两种新皂苷。它们的结构被确定为3 - O - [α - L - 鼠李糖基 - (1→2) - β - D - 葡萄糖醛酸基] - 2β - 3β - 16 - α - 三羟基 - 齐墩果 - 12 - 烯 - 23,28 - 二酸的28 - O - [α - L - 鼠李糖基 - (1→2 - [(α - L - 鼠李糖基) - (1→3) - ] - (β - D - 4 - 乙酰氧基岩藻糖基]酯和3 - O - [α - L - 鼠李糖基 - (1→2) - β - D - 葡萄糖醛酸基] - 2β - 3β - 16 - α - 三羟基 - 齐墩果 - 12 - 烯 - 23,28 - 二酸的28 - O - [α - L - 鼠李糖基 - (1→2 - [α - L - 鼠李糖基(1→3)] - (β - D - 岩藻糖基]酯。
