Abstract

Phytoecdysteroid glucosides, brainesterosides A-E, were isolated from the rhizomes of Brainea insignis along with three known phytoecdysteroids, ponasteroside A, ponasterone A, and 20-hydroxyecdysone. Their structures were elucidated by spectroscopic and chemical means. A possible biogenetic pathway is postulated for these compounds. The chemosystematic significance of ponasterone A is discussed.
