7-Hydroxywithanolides from Datura ferox
Three new withanolides were isolated from leaves of Datura ferox. Their structures were established as (17R,20S,22R)-5α,6α,7β,12α-tetrahydroxy- 1-oxowitha-2,24-dienolide (1), (17R,20S,22R,24S,25S)-24,25-epoxy- 5α,6α,7β,12α-tetrahydroxy-1-oxowitha-2-enolide (2), and (17R,20S,22R)- 5α,6α-epoxy-7α-hydr...
