Allimacrosides A-E, new steroidal glycosides from Allium macrostemon Bunge.
A new pregnane-type steroidal glycoside (1), two new spirostane-type steroidal glycosides (2, 3), and two new furostane-type steroidal glycosides (4, 5), named allimacrosides A-E, together with four known compounds (6-9) were isolated from a 80% MeOH extract of Allium macrostemon Bunge. The identification and structural elucidation of these compounds were based on their 1D- and 2D-NMR spectra, ...
متن کاملTwo new steroidal saponins from Allium macrostemon bunge and their cytotoxity on different cancer cell lines.
Two new steroidal saponins (1 and 2) were isolated from the dried bulbs of Allium macrostemon Bunge. Their structures were elucidated by the spectral data as 26-O-beta-D-glucopyranosyl-5alpha-furost-25 (27)-ene-3beta, 12beta, 22, 26-tetraol-3-O-beta-D-glucopyranosyl (1-->2) [beta-D-glucopyranosyl (1-->3)]-beta-D-glucopyranosyl (1-->4)-beta-D-galactopyranoside (1) and 26-O-beta-D-glucopyranosyl-...
متن کاملFirst Genome Sequence of Shallot Latent Carlavirus from Allium macrostemon Bunge
A wild Japanese garlic plant (Allium macrostemon Bunge, wild onion) with leaves showing chlorotic stripes was collected in Saitama Prefecture, Japan. Genome sequencing showed that it was infected with shallot latent carlavirus. The genomic sequence of this virus is reported for the first time from wild onion.
متن کاملNew cucurbitane triterpenoids and steroidal glycoside from Momordica charantia.
Three new cucurbitane triterpenoids 1-3 and one new steroidal glycoside 4, were isolated together with ten known compounds from Momordica charantia. The structures of new compounds were determined to be 19(R)-n-butanoxy-5 beta,19-epoxycucurbita-6,23-diene-3beta,25-diol 3-O-beta-glucopyranoside (1), 23-O-beta-allopyranosylecucurbita-5,24-dien-7 alpha,3beta,22(R),23(S)-tetraol 3-O-beta-allopyrano...
متن کاملSteroidal saponins from the bulbs of Allium karataviense.
Chemical examination of the bulbs of Allium karataviense led to the isolation of five new spirostanol saponins (7-11) and a new furostanol saponin (12), together with a known steroidal sapogenin (1) and five known saponins (2-6). The structures of the new saponins were determined by detailed analysis of their spectral data, including two-dimensional NMR spectroscopy. The steroidal saponins prod...
