Bioactive cycloartane-type triterpene glycosides from Astragalus elongatus.
Together with two known cycloartane-type glycosides, askendosides D (3-O-[alpha-arabinopyranosyl-(1-->2)-beta-xylopyranosyl]-6-O-beta-xylopyranosyl-cycloastragenol, 2) and G (3-O-[alpha-arabinopyranosyl-(1-->2)-beta-xylopyranosyl]-16-O-beta-glucopyranosyl-3 beta,6 alpha,16 beta,24(R),25-pentahydroxycycloartane, 3), also a new monodesmosidic cycloartane-type glycoside, elongatoside (1), was isol...

One new cycloartane-type saponin, 3-O-[β-D-xylopyranosyl-(1→2)-β-D-xylopyranosyl]-6-O-β-Dglucuronopyranosyl-3β,6α,16β,24(S),25-pentahydroxyxyxloartane (1) was isolated from the MeOH extract of whole plant parts of Astragalus erinaceus along with 5 known saponins (2-6), cyclodissectoside, cycloastragenol, 6-O-β-D-glucopyranosyl-3β,6α,16β,24(S),25-pentahydroxycycloartane, oleifolioside B and 3,6d...
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)...
متن کاملTrojanosides I-K: new cycloartane-type glycosides from the aerial parts of Astragalus trojanus.
Three new cycloartane-type triterpene glycosides have been isolated from the aerial parts of Astragalus trojanus. The structures were established mainly by a combination of one- and two-dimensional NMR techniques [1H-1H-correlation spectroscopy (COSY), 1H-13C-heteronuclear multiple quantum correlation spectroscopy (HMQC), and 1H-13C-heteronuclear multiple-bond correlation spectroscopy (HMBC)] a...
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...
