Garcipyran, a Novel 6-Aryl-1,2-benzopyran Derivative from Garcinia kola

Abstract

A novel 6-aryl-l,2-benzopyran derivative named garcipyran was isolated from the roots of Garcinia kola (Guttiferae) and the structure was elucidated by spectroscopic and chemical methods.The plausible biogenetic pathways of 6-alyl-1.2-benzopyran(garcipyran) and 5-arylbenzofuran (garcifuran-
