Plant Anticancer Agents, XXXIV. Cucurbitacins From Elaeocarpus dolichostylus

Abstract

Elaeocarpus dolichostylus has afforded the new cucurbitacin derivative, hexanorcucurbitacin F (3), whose structure was determined by spectroscopic and chemical correlation with curcurbitacin F (1). Cucurbitacin F (1) and 23,24-dihydrocucurbitacin F (2) were also isolated in this study.
