Abstract
One alpha-pyrone, obolactone (1), two chalcones, kurzichalcolactone B (2) and obochalcolactone (3), and two flavanones, oboflavanones A (4) and B (5), have been isolated from the fruits and the trunk bark of Cryptocarya obovata. The structures of the new compounds were elucidated by spectroscopic interpretations. The absolute configuration of obolactone (1) was established by circular dichroism. Obolactone (1) and obochalcolactone (3) display significant activity in in vitro cytotoxic assays against the KB cell line. Biosynthetic pathways for oboflavanones and obochalcolactone are suggested.Entities:
