摘要：
Two new withanolides named as withametelinol-A (1) and withametelinol-B (2) have been isolated from the aerial parts of Datura innoxia. Their structures have been elucidated as (20R, 22R)-21,24-epoxy-5beta-hydroxy-1-oxowitha-2,9(11),25(27)-trienolide and (20R, 22R)-21,24-epoxy-12alpha-hydroxy-1-oxowitha-3,5,25(27)-trienolide respectively through spectroscopic studies.
