| Abstract;From the underground parts of Eskemukerjea megacarpum HARA, two new stilbenes (14, 15) were isolated, together with a known coumarin, 5,7-dihydroxycoumarin (1), a tyramine derivative, trans-feruloyltyramine (2), two pyrogallol derivatives, gallic acid (3) and .BETA.-glucogallin (4), four flavonoids, trifolin (5), hyperin (6), myricetin 3-O-.BETA.-D-galactopyranoside (7), and myricitrin (8), five stilbenes, resveratorol (9), astringenin (10), piceid (11) astringin (12), and resveratorol 3-O-.BETA.-D-(6-O-galloyl)glucopyranoside (13), a flavan-3-ol, (-)-epigallocatechin 3-O-gallate (16), two proanthocyanidins, catechin-(4.ALPHA..RAR.8)-epigallocatechin 3-O-gallate (17) and epicatechin 3-O-gallate-(4.BETA..RAR.8)-epigallocatechin 3-O-gallate (18), and an anthocyanin, idaein (19). Compounds 14 and 15 were identified as (E)-3,5,3',4'-tetrahydroxystilbene 3-O-.BETA.-D-(6-O-galloyl)glucopyranoside and (E)-3,5,4'-trihydroxystilbene 3-O-.BETA.-D-(6-O-galloyl)glucopyranoside, respectively, based on spectral and chemical data.
