Flavonoid triglycosides from the seeds of Syzygium aromaticum

Two new apigenin triglycosides, apigenin 6-C-[β-d-xylopyranosyl-(1‴→2″)-β-d-galactopyranoside]-7-O-β-d-glucopyranoside and apigenin 6-C-[β-d-xylopyranosyl-(1‴→2″)-β-d-galactopyranoside]-7-O-β-d-(6⁗-O-p-coumarylglucopyranoside) were isolated from the ethanol extract of the seeds of Syzygium aromaticum. Their structures were elucidated by chemical and spectral analysis (UV, FABMS, 1H, 13C NMR, HMQC, HMBC, NOESY and DEPT).
