Chemical constituents from the stem bark of Trewia nudiflora

摘要

Trewia nudiflora L. is the only member of the genus Trewia (Euphorbiaceae), which is mainly distributed in India, Malaysia, and southwest of China. Previous studies have shown that the seed of T. nudiflora is a rich source of maytansinoid tumor inhibitors [1, 2]. Phytochemical studies are mainly focused on the seed and pericarp of the plant; however, there are only few reports on its stem bark [3, 4].
