  摘要：

  Three new cyclolanostanol xylosides were isolated from a batch of commercial Cimicifuga Rhizome, cimicifugoside H-1 (1), C35H52O9, mp 260-262°C, [α]D -43.5°, cimicifugoside H-2 (2), C35H54O10, mp 227-229°C, [α]D -38.8°, and cimicifugoside H-5 (3), C35H52O10, mp 262-264°C, [α]D -22.9°, together with known glycosides, actein and 27-deoxyactein. Their structures were determined on the basis of chemical and spectrometric evidence including an X-ray crystallographic analysis. The structure of cimicifugoside H-1 (1) was established as (20R, 24R)-24, 25-epoxy-11β-hydroxy-3-β-(β-D-xylopyranosyloxy)-9, 19-cyclolanost-7-ene-16, 23-dione. Cimicifugoside H-5 (3) is the 15-hydroxylated derivative of 1. Since 1 changed into cimicifugoside H-2 (2) on treatment with p-toluenesulfonic acid, 2 has a 24R, 25-diol structure derived from 1 by opening its epoxy ring.

  Neutral constituents of Cimicifuga foetida L. were examined. Eight new triterpenoids and three new trinor-triterpenoids were isolated from the rhizoma of C. foetida L. (Ranunculaceae) along with six known compounds and their structures were determined by the use of 2D NMR techniques and chemical methods.

  Three trinor-triterpenol glycosides were isolated from a batch of commercial Cimicifuga Rhizome : cimicifugoside H-3 (1), C32H48O9, mp 249-251 °C, [α]D -22.3°, cimicifugoside H-4 (2), C32H48O9, mp 265-267 °C, [α]D -75.0°, and cimicifugoside H-6 (3), C32H<48>O10, mp 275-276 °C, [α]D -64.3°, On the basis of chemical and spectral data, the structure of 1 was proposed to be 11β, 24-dihydroxy-3β-(β-D-xylopyranosyloxy)-25, 26, 27-trinor-9, 19-cyclolanost-7-ene-16, 23-dione. Cimicifugoside H-4 (2), 11β, 16α, 24α-trihydroxy-3β-(β-D-xylopyranosyloxy)-25, 26, 27-trinor-9, 19 : 16, 24-dicyclolanost-7-en-23-one, seems to be generated from intramolecular aldol condensation between C-16 and C-24 of 1. Cimicifugoside H-6 (3) is the 15α-hydroxy derivative of 2. Cimicifugoside H-2 (5), which has already been obtained from cimicifugoside H-1 (4) under an acidic condition, was found to give 1, 2 and an α-hydroxy enone (2a) under an alkaline condition.
