Abstract

5-geranoxy-7-methoxy-coumarin, isoimperatorin, bergapten and 5-geranyloxy psoralen (bergamottin) were isolated for the first time from the fruit of Citrus grandis Osbeck (= Citrus decumana Murr.) Their identity was confirmed by spectral methods as well as comparison with authentic samples.
