Withanolides from Withania coagulans.
Two withanolides, 20beta-hydroxy-1-oxo-(22R)-witha-2,5,24-trienolide (1) and withacoagulin (2), along with a known withanolide, 17beta-hydroxy-14alpha, 20alpha-epoxy-1-oxo-(22R)-witha-3,5,24-trienolide (3) were isolated from Withania coagulans. Their structures were elucidated with the help of different spectroscopic techniques.
