ABSTRACT
The leaf essential oil of an undescribed species of Myrcianthes has been obtained from Monteverde, Costa Rica. The essential oil exhibits in vitro cytotoxic activity against Hep-G2 and SK-Mel-28 human tumor cell lines. A GC/MS analysis shows the essential oil to be composed of 2-heptanol, alpha-pinene, beta-pinene, limonene, cineole, and alpha-terpineol, alpha-Pinene, beta-pinene, and limonene account for the cytotoxic activity of the leaf essential oil of Myrcianthes sp. nov. "black fruit".
