Abstract


Aralia hiepiana J.Wen & Lowry (Araliaceae), a new species from southern Vietnam, is described and illustrated by J. Wen & Lowry in 2002. Up to now, there are not any chemical data from this endemic species. By various chromatography methods, four flavonoids compounds namely kaempferol 3,7-O-α-L-dirhamnopyranoside (1), kaempferol 3-O-β-D-glucopyranosyl-7-O-a-L-rhamnopyranoside (2), kaempferol (3), quercetin (4), apigenin 7-O-β-glucopyranoside (5) were isolated from the methanol extract of leaves of Aralia hiepiana collected in Da Lat, Lam Dong province. Their structures were elucidated using 1-D and 2-D NMR techniques and by comparison with the literature data. This is the first time to isolate these compounds from Aralia hiepiana.
