Isolation and structural elucidation of some chemical constituents from Adinandra poilanei Gagnep.

Abstract

Adinandra genus (Pentaphylacaceae family) comprised over 100 species, among that more than 10 species distributed in Vietnam. Several Adinandra plants have been used for the treatment of cancer, snake bite, and stomach aches. Phytochemical study of A. poilanei stems collected in Lam Dong province led to the isolation of five compounds including lupeol (1), 2β-hydroxypomolic acid (2), 2,6-dimethoxy-1,4-benzoquinone (3), scopoletin (4), and tyrosol (5). Compounds 2-5 were isolated from the Adinandra genus for the first time.
