Five new triterpene glycosides were isolated from the methanolic extract of Thalictri Herba (Takatogusa), the dried aerial parts of Thalictrum sp. plants (Ranunculaceae). They were designated as thalictosides III (1) and IV (2), being cycloartane-type glycosides, and thalictosides VI (3), VII (4) and VIII (5), being oleanene-type glycosides. By chemical and spectroscopic evidence, their structures were elucidated as 22R-21S,23R-epoxy- and 22R-21R,23R-epoxy-21-methoxycycloart-24-en-3 beta,22,30-triol 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->6)]- beta-D-glucopyranosides (1 and 2, respectively), 3-O-beta-D-glucopyranosyl-(1-->3)-alpha-L- rhamnopyranosyl-(1-->4)-beta-D-xylopyranosyl hederagenin 28-O-beta-D-glucopyranosyl ester (3) and 3-O-alpha-L-rhamnopyranosyl-(1-->3)-beta-D-glucopyranosyl-(1-->3)-alpha- L- rhamnopyranosyl-(1-->4)-beta-D-xylopyranosyl oleanolic acid and hederagenin 28-O-beta-D-glucopyranosyl esters (4 and 5, respectively).
从毛茛科唐松草属植物唐松草（Takatogusa）干燥地上部分的甲醇提取物中分离出5种新的三萜糖苷。它们被命名为唐松草苷III（1）和IV（2），属于环阿尔廷烷型糖苷，以及唐松草苷VI（3）、VII（4）和VIII（5），属于齐墩果烷型糖苷。通过化学和光谱证据，确定它们的结构分别为22R-21S,23R-环氧-和22R-21R,23R-环氧-21-甲氧基环阿尔廷-24-烯-3β,22,30-三醇3-O-α-L-鼠李吡喃糖基-(1→2)-[α-L-鼠李吡喃糖基-(1→6)]-β-D-葡萄糖吡喃糖苷（分别为1和2）、3-O-β-D-葡萄糖吡喃糖基-(1→3)-α-L-鼠李吡喃糖基-(1→4)-β-D-木糖吡喃糖基常春藤皂苷元28-O-β-D-葡萄糖吡喃糖基酯（3）以及3-O-α-L-鼠李吡喃糖基-(1→3)-β-D-葡萄糖吡喃糖基-(1→3)-α-L-鼠李吡喃糖基-(1→4)-β-D-木糖吡喃糖基齐墩果酸和常春藤皂苷元28-O-β-D-葡萄糖吡喃糖基酯（分别为4和5）。
