Three new 15,16-seco-cycloartane glycosides from Cimicifuga Rhizome.
Three new 15,16-seco-cycloartane glycosides, which were constructed by a C-C bond cleavage in the D ring, have been isolated from Cimicifuga Rhizome for the first time. Their structures were determined by the use of 2D NMR techniques and chemical evidence.
متن کاملCycloartane glycosides from Cimicifuga dahurica.
A new cycloartane bisdesmoside and two new trinorcycloartane glycosides, along with four known cycloartane compounds, were isolated from the rhizomes of Cimicifuga dahurica (Ranunculaceae). The structures of the new compounds were elucidated as 3-O-alpha-L-arabinopyranosyl cimigenol 15-O-beta-D-glucopyranoside, 24-hydroxy-12beta-acetoxy-25,26,27-trinorcycloartan-16,23-dione 3beta-O-alpha-L-arab...

Three new trinor-cycloartane glycosides, 15alpha-hydroxy-16-dehydroxy-16(24)-en-foetidinol-3-O-beta-D-xylopyranoside (1), 28-hydroxy-foetidinol-3-O-beta-D-xylopyranoside (2) and foetidinol-3-O-beta-D-xylopyranosyl-(1"-->3')-beta-D-xylopyranoside (3) together with the known compound foetidinol-3-O-beta-D-xylopyranoside (4) were isolated from the n-BuOH fraction of the roots of Cimicifuga foetida...
متن کاملThree new cycloartane triterpene glycosides from Souliea vaginata.
Three new cycloartane triterpene glycosides, soulieosides A (1), B (2), and C (3), were isolated from the rhizomes of Souliea vaginata, and their structures were elucidated on the basis of extensive NMR experiments and chemical methods. Soulieosides A-C were assigned as 25-O-acetylcimigenol-3-O-beta-D-(2-acetyl)xylopyranoside (1), 24-O-acetyl-isodahurinol-3-O-beta-D-(2-acetyl)xylopyranoside (2)...
