Phytoecdysteroids from the juice of Serratula coronata L. (Asteraceae).
Seven phytoecdysteroids have been isolated from Serratula coronata L. One of them is a new phytoecdysteroid, 3-epi-20-hydroxyecdysone. Two further ecdysteroids, 20-hydroxyecdysone 22-acetate and taxisterone, are isolated from this species for the first time in addition to the typical S. coronata ecdysteroids, 20-hydroxyecdysone, ecdysone, ajugasterone C and polypodine B. The juice squeezed from...
متن کاملNovel Ecdysteroids from Serratula wolffii
Two new and one known ecdysteroids were identified in the methanolic extract of the roots of Serratula wolffii. The new compounds isolated were ponasterone A-22-apioside (1) and 3-epi-shidasterone (3), together with the known 3-epi-22-deoxy-20-hydroxyecdysone (2). The structures of compounds 1-3 were determined by extensive spectroscopic techniques, including one- and two-dimensional NMR methods.
متن کاملCerebrosides from the roots of Serratula chinensis.
A new cerebroside, 1-O-beta-D-glucopyranosyl-(2S,3R,8E)-2-[(2'R)-2-hydroxy- palmitoylamino]-8-octadecene-1,3-diol, along with aralia cerebroside and 1-O-beta-D- glucopyranosyl-(2S,3S,4R,8E)-2-[(2'R)-2-hydroxybehenoylamino]-8-octadecene-1,3,4-triol were isolated from the roots of Serratula chinensis S. Moore. The structure of the new cerebroside was established by spectroscopic and chemical mean...
متن کاملSeparation Methods for Phytoecdysteroids
Introduction The effectiveness of natural health preparations is based on the amount/ratio of their active ingredients. This can differ in plants depending on the species variant, the part of the plant used, the season or the micro-climate. Moreover, the method of harvest, the drying and extraction techniques used, and any further processing also influence the final composition of medicinal hea...
متن کاملPhytoecdysteroids from the roots of Achyranthes bidentata Blume.
Two new phytoecdysteroids, (25S)-20,22-O-(R-ethylidene)inokosterone and 20,22-O-(R-3-methoxycarbonyl)propylidene-20-hydroxyecdysone, together with six known phytoecdysteroids 3-8 were isolated from the roots of Achyranthes bidentata Blume. The new structures were established on the basis of spectroscopic studies and chemical evidences. The absolute configuration at C-25 in the structure of know...
