A new triterpene ester and other chemical constituents from the aerial parts of Anodendron paniculatum and their cytotoxic activity

Abstract

The aim of the research was to study the active constituents of Anodendron paniculatum Roxb. (Apocynaceae). A new triterpene ester, named anopaniester (1), and cycloartenol (2), ursolic acid (3), esculenic acid (4), bis-(2-ethylhexyl) phthalate (5), desmosterol (6), stigmasterol (7), vaniline (8), and (E)-phytol (9), were isolated from the aerial parts of A. paniculatum. Compounds 3 and 6 showed the significant inhibitory effect (IC₅₀ values ranging from 30.89 ± 3.60 to 44.37 ± 5.40 μg/ml) against tested human cancer cell lines LU-1 and MKN-7. The compounds 1–4, and 6 were isolated from this genus Anodendron for the first time.
