Flavonoid galloyl glucosides from the pods of Acaciafarnesiana
摘要:
Three new flavonoids: naringenin 7-O-beta-(4",6"-digalloylglucopyranoside), quercetin 7-O-beta-(6"-galloylglucopyranoside) and myricetin 7-O-beta-(6"-galloylglucoppranoside) were identified from the pods of Acacia farnesiana, together with naringenin and kaempferol 7-(6"-galloylglucoside). The structures were determined by conventional methods of analysis and confirmed by ESI-MS (negative mode) and NMR spectroscopy. (C) 1999 Elsevier Science Ltd. All rights reserved.
