New spirorotenoids from Tephrosia candida

Z Naturforsch C J Biosci. 2002 May-Jun;57(5-6):418-22. doi: 10.1515/znc-2002-5-602.

Abstract

The ethyl acetate extract of roots of Tephrosia candida afforded three new spirorotenoids belonging to a new class of spirocompounds, named tephrospirolactone, tephrospiroketone I, and tephrospiroketone II. The structures of these compounds were determined mainly based on spectral analysis. The only known spirorotenoid described in the literature is amorphispironone, isolated from Amorpha fruticosa.
