Two new phenylpropanoid glycosides, 9-O-[6-O-acetyl-β-d-glucopyranosyl]-4-hydroxycinnamic acid (1) and 8-O-β-d-glucopyranosyl-(R)-(+)-3,4,8-trihydroxy methyl phenylpropionate (2) were isolated from the 80% EtOH extract of the roots of Sanguisorba officinalis. Their structures were characterized by spectroscopic analysis and chemical method, including 1D NMR, 2D NMR, and HR-ESI-MS. Compounds 1 and 2
两种新的苯基丙烷苷,9- O- [6 - O-乙酰基-β - d-吡喃葡萄糖基] -4-羟基肉桂酸(1)和8 - O - β -d-吡喃葡萄糖基-(R)-(+)-3从Sanguisorba officinalis根的80%EtOH提取物中分离出4,4,8-三羟甲基苯丙酸酯(2)。通过光谱分析和化学方法(包括1D NMR,2D NMR和HR-ESI-MS)对它们的结构进行了表征。化合物1和2对测试的所有革兰氏阳性菌和革兰氏阴性菌均表现出中等的抗菌活性。
