Abstract
Two new antifungal withanolides (1) and (2) have been isolated from the def atted methanolic extract of Ajuga parviflora. Their structures were establi shed as 3 beta,1 beta,20-trihydroxy-1-oxo -(20R, 22R)-witha-5,13,24-trienol ide (1), 28-hydroxy-14,20-epoxy-1 -oxo-(22R)-witha-2,5,24-trienolide (2) on the basis of spectroscopic data including two dimensional NMR techniques. The pyrrolizidine alkaloids senecionine (3) and integerrimine (4) are also reported for the first time from A. parviflora.
