| Abstract | ||
| Three phenylethanoid glycosides viz; -[(3′,4′-dihydroxyphenyl)-ethyl]-(4′َ′-O-caffeoyl)-- D-glucoside (desrhamnosylacteoside) (1), -[(3′,4′-dihydroxyphenyl)-ethyl]-(3′′-O-Lrhamnosyl)-( 4′′-O-caffeoyl)- -D-glucoside (acteoside) (2) and -[(3′,4′-dihydroxyphenyl)- ethyl]-(3′′,6′′-O-L-dirhamnosyl)-(4′′-O-caffeoyl)- -D-glucoside (poliumoside) (3) were isolated and identified from the callus cultures of Barleria cristata L.The structures of the isolated compounds were established by spectroscopic evidence (UV, 1D and 2D-NMR and ESIMS), further confirmation has been done by comparison with authentic samples. The amount of compounds 1-3 were determined in the callus culture using HPLC. | ||
