Sesterterpenes and other constituents of Salvia yosgadensis

Abstract

From the aerial parts of Salvia yosgadensis we have obtained two new sesterterpenes, yosgadensolide A (6 alpha,14-dihydroxymanoyloxide-15,17-dien-16,19-olide) and yosgadensolide B (6 alpha,16-dihydroxymanoyloxide-14,17-dien-16,19-olide) and their epimers. In addition, a known sesquiterpene, three known sesquiterpene lactones, eight known flavonoids and two known aromatics were isolated.
