Abstract
|
|
|
|
Investigations on the chemical constituents of the fruits of Prunus armeniaca have led to the isolation of two new flavonoid glycosides, 4’,5,7-trihydroxy flavone-7-O-[β-D-mannopyranosyl (1’’’→2’’)]-β-D-allopyranoside (1) and 3,4’,5,7-tetrahydroxy-3’,5’-di-methoxy flavone 3-O-[α-Lrhamnopyranosyl (1’’’→6’’)]-β-D-galactopyranoside (2), from the butanolic fraction of the fruits. The butanolic extract exhibited antibacterial activity against both Gram positive and Gram negative bacteria. The structures of these compounds were elucidated through spectral studies, including 2D-NMR (COSY, NOESY, J-resolved), HMQC and HMBC experiments.
