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-[beta-D-mannopyranosyl (1'''-->2")]-beta-D-allopyranoside (1) and 3,4',5,7-tetrahydroxy-3',5'-di-methoxy flavone 3-O-[alpha-L-rhamnopyranosyl (1'''-->6")]-beta-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.
对杏果实化学成分的研究导致从果实的正丁醇部分分离出两种新的黄酮苷，4',5,7-三羟基黄酮-7-O-[β-D-甘露吡喃糖基(1'''→2")]-β-D-阿洛吡喃糖苷(1)和3,4',5,7-四羟基-3',5'-二甲氧基黄酮3-O-[α-L-鼠李吡喃糖基(1'''→6")]-β-D-吡喃半乳糖苷(2)。正丁醇提取物对革兰氏阳性菌和革兰氏阴性菌均表现出抗菌活性。这些化合物的结构通过光谱研究得以阐明，包括二维核磁共振(COSY、NOESY、J-分解)、HMQC和HMBC实验。
