Steroidal Glycosides from Convallaria majalis Whole Plants and Their Cytotoxic Activity
Phytochemical examination of Convallaria majalis (Liliaceae) whole plants yielded 15 steroidal glycosides (1-15), including nine new compounds (4-6, 10-15) with a lycotetrose unit. The structures of the new compounds were determined using two-dimensional Nuclear magnetic resonance (NMR) analyses and chemical methods. The isolated compounds were evaluated for cytotoxicity against HL-60 human pro...
متن کاملNovel Steroidal Glycosides from the Bulbs of Lilium pumilum.
Examination of the bulbs of Lilium pumilum (Liliaceae) led to the isolation of four novel steroidal glycosides (1-4) with a 2,3,4-trisubstituted β-d-glucopyranosyl unit. In 1 and 3, the α-L-arabinopyranosyl moiety is linked to C-3 of the inner trisubstituted β-D-glucopyranosyl group and is present as an usual ⁴C₁ conformation. In contrast, in 2 and 4, the α-L-arabinopyranosyl moiety, which is a...
متن کاملStudies on the constituents of solanaceous plants. (46). Steroidal glycosides from the fruits of Solanum anguivi.
Three new glycosides named anguiviosides A-C were isolated from the fruits of Solanum anguivi and characterized as follows:3-O-beta-chacotrioside (1), 3-O-[4-O-maloyl-alpha-L-rhamnopyranosyl(1-->2)]-alpha-L-rhamnopyra nosyl(1-->4)-beta-D-glucopyranoside (2) and 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D-xylopyranosyl(1-->3)]-beta-D-+ ++glucopyranoide (3), of (25R,26R)-spirost-5-en-3beta,26-diol.
متن کاملThree New Steroidal Glycosides from the Roots of Cynanchum stauntonii
Three new steroidal glycosides, named as stauntosides L, M, and N (1-3), along with one known C21 steroidal glycoside, anhydrohirundigenin monothevetoside (4), were isolated from the 95% ethanol extract of the roots of Cynanchum stauntonii. The structures of these new compounds were elucidated on the basis of extensive spectroscopic analyses, mainly 1D and 2D NMR, HRESI-MS, and chemical methods.
متن کاملThree new steroidal glycosides from the roots of Cynanchum auriculatum.
Three new steroidal glycosides, cyanoauriculosides F, G and H (1-3), were isolated from the roots of Cynanchum auriculatum (Asclepiadaceae) along with two known steroidal derivatives. On the basis of spectroscopic analysis and chemical methods, their structures were identified as 20-O-acetyl-8,14-seco-penupogenin-8-one 3-O-α-L-cymaropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-α-L-diginopyranosyl-...
