New sesquiterpenoids from Aglaia odorata var. microphyllina and their cytotoxic activity

One new norsesquiterpene (1), and four new sesquiterpenes (2 – 5), along with four known ones, were isolated from the twigs of Aglaia odorata var. microphyllina C. DC. Monogr. Their structures were established based on spectroscopic methods including HR-ESI-MS, 1D, and 2D NMR. Compounds 1, 3, and 6 showed cytotoxic activity against SGC-7901 tumor cell.
