The dichloromethane extract of the leaves of Myrica serrata inhibits growth of Cladosporium cucumerinum, Bacillus subtilis, and Escherichia coli on TLC plates. Activity-guided fractionation led the isolation of 2',4'-dihydroxy-6'-methoxy-3',5'-dimethylchalcone (1), 2',4'-dihydroxy-6'-methoxy-5'-methylchalcone (aurentiacin A) (2), 2',6'-dihydroxy-4'-methoxy-3',5'-dimethyldihydrochalcone (3), 2'-hydroxy-4',6'-dimethoxy-3'-methyldihydrochalcone (4), and 2', 6'-dihydroxy-4'-methoxy-3'-methyldihydrochalcone (5). In addition, the flavanones demethoxymatteucinol (6) and cryptostrobin (7) were also identified.
杨梅叶的二氯甲烷提取物在薄层色谱板上可抑制黄瓜枝孢、枯草芽孢杆菌和大肠杆菌的生长。通过活性导向分离法分离出了2',4'-二羟基-6'-甲氧基-3',5'-二甲基查耳酮（1）、2',4'-二羟基-6'-甲氧基-5'-甲基查耳酮（橙黄菌素A）（2）、2',6'-二羟基-4'-甲氧基-3',5'-二甲基二氢查耳酮（3）、2'-羟基-4',6'-二甲氧基-3'-甲基二氢查耳酮（4）以及2',6'-二羟基-4'-甲氧基-3'-甲基二氢查耳酮（5）。此外，还鉴定出了黄烷酮去甲氧基马特西诺醇（6）和隐丹参酮（7）。
