چکیده
Cyclo-art-24-ene-3β,26-diol, C(30)H(50)O(2), isolated from the leaves of Aglaia exima, has three six-membered rings fused together that adopt chair conformations. There are two independent mol-ecules in the asymmetric unit. O-H⋯O hydrogen bond inter-actions between the hydroxyl groups in the 3β and 26 positions lead to the formation of a layer structure parallel to (10).

Triterpenes and steroids from the leaves of Aglaia exima (Meliaceae).
A study on the leaves of Aglaia exima led to the isolation of one new and seven known compounds: six triterpenoids and two steroids. Their structures were elucidated and analyzed mainly by using spectroscopic methods; 1D and 2D NMR, mass spectrometry, UV spectrometry and X-ray. All the triterpenoids and steroids were measured in vitro for their cytotoxic activities against eight cancer cell lin...
