Steroidal Saponins from the Rhizomes of Anemarrhena asphodeloides.
Four new steroid saponins 1-4 were isolated from the rhizomes of Anemarrhena asphodeloides (Asparagaceae), as well as four known saponins: anemarsaponin B (5) timosaponin D (6), timosaponin E1 (7) anemarsaponin B II (8). Their structures were established through UV and NMR as well as MS data. All the compounds were evaluated for cytotoxicity against HepG2 and SGC7901 human cancer lines. Compoun...
متن کاملAnemarrhena asphodeloides Non-Steroidal Saponin Components Alter the Pharmacokinetic Profile of Its Steroidal Saponins in Rat.
A rapid, selective and sensitive UPLC-MS/MS assay was established to determine the plasma concentrations of four steroidal saponins. Sprague-Dawley rats were allocated to four groups which were orally administered Anemarrhena asphodeloides extracts (ASE), ASE combined with macromolecular fraction (ASE-MF), ASE combined with small molecule fraction (ASE-SF) and ASE combined with small molecule a...
متن کاملSteroidal Saponins from the Rhizomes of Aspidistra typica
Eleven new furostanol saponins, typaspidosides B-L (1-11), one new spirostanol saponin, typaspidoside M (12), and five known spirostanol saponins, 25S-atropuroside (13), neoaspidistrin (14), (25S)-pratioside D1 (15), 25S-aspidistrin (16) and 25S-neosibiricoside (17) were isolated from the rhizomes of Aspidistra typica Baill. The structures of the new compounds were established using 1D and 2D N...
متن کاملSteroidal Saponins from the Roots and Rhizomes of Tupistra chinensis.
Two new furostanol saponins 1-2 and a new spirostanol saponin 3 were isolated together with two known furostanol saponins 4-5 from the roots and rhizomes of Tupistra chinensis. Their structures were characterized as 1β,2β,3β,4β,5β,26-hexahydroxyfurost-20(22), 25(27)-dien-5,26-O-β-d-glucopyranoside (1), 1β,2β,3β,4β,5β,6β,7α,23ξ,26-nona-hydroxyfurost- 20(22),25(27)-dien-26-O-β-d-glucopyranoside (...
متن کاملNew steroidal saponins from rhizomes of Costus spiralis.
Two new steroidal saponins were isolated from the rhizomes of Costus spiralis Rosc. Their structures were established as (3beta,25R)-26-(beta-D-glucopyranosyloxy)-22-hydroxyfurost-5-en-3-yl O-D-apio-beta-D-furanosyl-(1-->2)-O-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucopyranoside (1) and (3beta,25R)-26-(beta-D-glucopyranosyloxy)-22-hydroxyfurost-5-en-3-yl O-D-apio-beta-D-furanosyl-(1-->4)-O-[...
