TL;DR: From the rhizomes of Anemone anhuiensis (Ranunculaceae), two new triterpene saponins, anhuienosides A and B, were isolated and their structures were elucidated on the basis of chemical and spectral evidence.
Abstract: From the rhizomes of Anemone anhuiensis (Ranunculaceae), two new triterpene saponins, anhuienosides A (1) and B (2), were isolated. These compounds are glycosylated at C-23 and their structures were elucidated as hederagenin 23-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside (1) and 23-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl hederagenin 28-O-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester (2) on the basis of chemical and spectral evidence.

TL;DR: Compounds I, II and V were isolated from this plant for the first time and are thought to be a new natural product, compound II is a new compound and compounds IV and V are new compounds.
Abstract: AIM To investigate the chemical constituents from the rhizomes of Cimicifuga acerina (Sieb et Zucc) Tanaka METHODS Column chromatgraphy (including silica gel and ODS) together with HPLC was used to separate the chemical constituents whose structures were determined by FAB-MS, NMR (1D and 2D) and hydrolysis methods RESULTS Five cycloartane triterpenoids were isolated and identified as: (22R)-22-hydroxycimigenol (I), (22R)-22-hydroxy-24- O -acetylhydroshengmanol 3- O -β- D -xylopyranoside (II), dahurinol (III), 24- epi -24- O -acetyl-7,8-didehydroshengmanol 3- O -β- D -xylopyranoside (IV), 25- O -acetyl-7,8-didehydrocimigenol 3- O -β- D -xylopyranoside (V) CONCLUSION Compound I is a new natural product, compound II is a new compound and compounds IV and V were isolated from this plant for the first time
