Withanolides from Vassobia lorentzii
Eight new withanolides were isolated from the aerial parts of Vassobia lorentzii and characterized by spectroscopic methods and with the aid of molecular modeling. The compounds were identified as (17S,20R,22R)-5β,6β:18,20-diepoxy-18-hydroxy-1-oxowitha-2,5,24-trienolide (1); (17S,20R,22R)-18,20-epox...
