ent-Kauranoid Diterpenes from Artemisia sacrorum

Abstract

A new ent-kauranoid diterpene diglycoside has been isolated from Artemisia sacrorum along with two known ent-kauranoid diterpenes. Their structures are elucidated by means of nmr analysis (DEPT, 1H-1H COSY, 1H-13C COSY, and 1H-1H decoupling).
