Photooxidation of nimbin and salannin, tetranortriterpenoids from the neem tree (Azadirachta indica)

Nimbin and salannin, major triterpenoids accompanying azadirachtin in extracts of neem (Azadirachta indica) seeds, were photooxidized by UV light in the presence of oxygen to more polar, unstable intermediates that rearranged on silica gel to two final products in which the furan ring had been oxidi...
