inokosterone/achyranthes bidentata

OBJECTIVE To isolate C-25 epimers of inokosterone from Achyranthes bidentata Blume. and identify their structures. METHODS To separate C-25 epimers of inokosterone by using various kinds of chromatography methods and identify their structures on basis of spectral analysis and chemical

OBJECTIVE To establish the fingerprints of Achyranthes bidentata Bl. by HPLC/UV/MS. METHODS Separation was performed on Aglient Zorbax SB-C18 column. Gradient elute was performed by the mobile phase consisting of methanol and 0.1% formic acid-water with the flow rate of 1.0 ml/min. RESULTS Perfect

Total ecdysones (ecdysterone and inokosterone) were isolated and identified from Achyranthes bidentata radix of polyploid and monoploid by column chromatography. The hormone contents of monoploid and diploid are about the same, but the content of polyploid is 14 times that of the diploid.

A simple, accurate and sensitive ultra high-performance liquid chromatography-tandem mass spectrometry approach was established for the simultaneous determination of β-ecdysterone, 25S-inokosterone, ginsenoside Ro, chikusetsusaponin IV and chikusetsusaponin IVa in rat plasma after oral

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

Background: Traditional Chinese medicine suggests that Radix Achyranthis Bidentatae nourishes and protects the kidneys, the effect of which is enhanced following a salt treatment. Raw and salt-processed Achyranthes bidentata are produced

To establish a standard of quality control and to identify reliable Achyranthis Radix, three phytoecdysones including ecdysterone (1), 25R-inokosterone (2) and 25S-inokosterone (3) were determined by quantitative HPLC/UV analysis. Three phytoecdysones were separated with an YMC J'sphere ODS C(18)

Achyranthes bidentata and Achyranthes aspera are saponin and steroid rich medicinal plants, used extensively for therapeutic treatments in Traditional Chinese Medicine (TCM) and Ayurveda. A. bidentata is reported to be one of the rare and extensively exploited medicinal plant species that face the
