Elsholtzia rugulosa Hemsl. is known in China as a local herbal tea, medicinal herb and honey plant. Chemical examination of E. rugulosa led to the isolation of two new flavonoid glycosides, apigenin 4'-O-α-D-glucopyranoside (1) and 5,7,3',4'-tetrahydroxy-5'-C-prenylflavone-7-O-β-D-glucopyranoside (2), together with nine known flavonoids. Their structures were elucidated on the basis of spectroscopic evidence.
香薷(Elsholtzia rugulosa Hemsl)在中国被称为当地的凉茶、药草和蜂蜜植物。对 E. rugulosa 进行化学检查,分离出两种新的类黄酮苷:芹菜素 4'-O-α-D-吡喃葡萄糖苷 (1) 和 5,7,3',4'-四羟基-5'-C-异戊二烯黄酮- 7-O-β-D-吡喃葡萄糖苷 (2),以及九种已知的黄酮类化合物。它们的结构是根据光谱证据阐明的。
