Abstract

Objective: To study the aqueous chemical constituents of the flower buds of Eugenia caryophylla.

Methods: The compounds were isolated by HP-20 resin column chromatography, RP-C18 column chromatography, preparative RP-C18 thin-layer chromatography, preparative RP-C18 high performance liquid chromatography, and their structures were established by NMR and MS evidences.

Results: Five compounds were separated from the water extracts. Their structures were identified as quercetin-3-O-glucuronide (1), quercetin-3-O-glucuronide 6"-methyl ester (2), quercetin-3-O-glucopy-ranoside (3) , eugenyl-beta-rutinoside (4) and myricetin (5).

Conclusion: Compounds 1-4 are isolated from the genus for the first time.
