Sterols and terpenoids from Melia azedarach.
Three new sterols (1-3) including an unprecedented ring A-seco natural product (1), five new terpenoids (4-8), and 15 known compounds were isolated from the bark of Melia azedarach. Their structures were elucidated by means of spectroscopic data, and the structure of 1 was confirmed by X-ray crystallography.
