One known (1) and two new cycloartane triglycosides, 20S,22R,23S,24R-16beta,23;22,25-diepoxy-cycloartane-3beta,23,24-triol 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-xylopyranoside (2) and 20S,22R,23S,24R-16beta,23;22,25-diepoxy-cycloartane-3beta,23,24-triol 3-O-(6-O-trans-isoferuloyl-beta-D-glucopyranosyl)-(1-->2)-beta-D-glucopyranosyl-(1-->2)-beta-D-xylopyranoside ...
متن کاملTwo new cycloartane glycosides from the underground parts of Aquilegia vulgaris.
Two new cycloartane glycosides, named aquilegiosides K and L, have been isolated from the dried underground parts of Aquilegia vulgaris. Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.
متن کاملCycloartane glycosides from the rhizomes of Cimicifuga racemosa and their cytotoxic activities.
Phytochemical analysis of the rhizomes of Cimicifuga racemosa (Ranunculaceae) resulted in the isolation of twelve cycloartane glycosides (1--12), including four new ones (4--6, 12). The structures of the new compounds were determined by spectroscopic analysis, including two-dimensional (2D) NMR data, and chemical methods. The isolated compounds were evaluated for their cytotoxic activities agai...
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...
