Cilistepoxide and cilistadiol, two new withanolides from Solanum sisymbiifolium.
In addition to the known cilistol A, two new withanolides have been isolated from leaves and stem of Solanum sisymbiifolium, and assigned the structures 1-oxo-5,6; 22,26; 24,25-triepoxy-17,26-dihydroxyergost-2-ene and 1-oxo-22,26; 24,25-diepoxy-5,6,17,26-tetrahydroxy ergost-2-ene, namely cilistepoxide and cilistadiol.
