Phytochemical and Bioactivity Studies of Zingiber amaricans Blume

摘要

Phytochemical studies on the rhizomes of Zingiber amaricans afforded zerumbone1 as the major constituent, together with sterol mixtures containing, stigmasterol2, ^-sitosterol3, cholesterol4 and campes-terol5. The structures of the isolated compoundswere elucidated using spectroscopic methods. The crude extracts and isolated pure compounds were examined for their bioactivity against photogenic microbes and cancer cell lines. Zerumbone1 shows moderate cytotoxic activity against human lymphoblastic Tleukemia cell.
