A new nuatigenin-type steroidal saponin, multifidoside (2), was isolated from the aerial parts of Veronica fuhsii and V multifida and its structure was identified as 3-O-([alpha-L-rhamnopyranosyl-(1-->2glu)]-[beta-D-glucopyranosyl-(1-->4rha)-alpha-L-rhamnopyranosyl (1-->4glu)]-beta-D-glucopyranosyl]nuatigenin 26-O-beta-D-glucopyranoside. Additionally, a known steroidal saponoside, aculeatiside A (1), from V. fuhsii, a phenylethanoid glycoside, verpectoside A (3), and a flavon glycoside, isoscutellarein 7-O-(2"-O-6"-O-acetyl-beta-D-allopyranosyl-beta-D-glucopyranoside) (4) from V. multifida were isolated.
从细叶婆婆纳和多裂婆婆纳的地上部分分离得到一种新的努阿替皂苷元型甾体皂苷——多裂皂苷（2），其结构鉴定为3 - O -（[α - L - 鼠李吡喃糖基 -（1→2）葡萄糖] - [β - D - 葡萄糖吡喃糖基 -（1→4）鼠李糖 - α - L - 鼠李吡喃糖基（1→4）葡萄糖] - β - D - 葡萄糖吡喃糖基）努阿替皂苷元26 - O - β - D - 葡萄糖吡喃糖苷。此外，还从细叶婆婆纳中分离得到一种已知的甾体皂苷——刺果皂苷A（1），从多裂婆婆纳中分离得到一种苯乙醇苷——婆婆纳苷A（3）和一种黄酮苷——异槲皮素7 - O -（2″ - O - 6″ - O - 乙酰基 - β - D - 阿洛吡喃糖基 - β - D - 葡萄糖吡喃糖苷）（4）。
