Phytochemistry. 1994 Dec;37(6):1659-62. doi: 10.1016/s0031-9422(00)89587-4.

Abstract

Three cytotoxic clerodane diterpenes were purified from an ethyl acetate-soluble extract of the stem bark of Polyalthia barnesii, namely, 16 alpha-hydroxycleroda-3,13(14)Z-dien-15,16-olide, a known compound, and two novel compounds, 3 beta, 16 alpha-dihydroxycleroda-4(18),13(14)Z-dien-15,16-olide and 4 beta, 16 alpha-dihydroxyclerod-13(14)Z-en-15,16-olide. These compounds were found to exhibit broad cytotoxicity against a panel of human cancer cell lines.
