In a flavonoid survey of five species ( D. alatus Roxb. & G.Don, D. costatus Gaertn. f., D. gracilis Blume, D. turbinatus Gaertn. f. and Hopea odorata Roxb . ) of Dipterocarpaceae from Bangladesh, three flavonoid aglycones and two glycosides were isolated. The flavonol kaempferol was detected in 40% of the total species surveyed, while the flavonol quercetin and flavone apigenin were present in all species examined, establishing their chemotaxonomic significance. Proanthocyanidins were found only in three species ( D. alatus , D. gracilis , D. turbinatus ), while the glycosides quercetin 3‐glucoside and quercetin 3‐rutinoside were isolated in 40% and 60% of the species surveyed, respectively. The flavonoid patterns of H. odorata and D. costatus are advanced in comparison to those of D. alatus , D. gracilis and D. turbinatus due to the loss of proanthocyanidin. © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society , 2003, 143 , 43−46.
