An investigation of Salvia officinalis L. has led to the isolation of three new phenolic glycosides, 6-O-caffeoyl-beta-D-fructofuranosyl-(2-->1)-alpha-D-glucopyranosid e (1), 1-O-caffeoyl-beta-D-apiofuranosyl-(1-->6)-beta-D-glucopyrano side (2), and 1-O-p-hydroxybenzoyl-beta-D-apiofuranosyl-(1-->6)-beta-D-glucop yranos ide (3). Elucidation of the structures of 1-3 was based on the interpretation of FABMS and 1D and 2D NMR spectra. Compounds 1 and 2 were found to be moderately active as antioxidants in the DPPH test and metmyoglobin test.
一项对鼠尾草的研究已导致分离出三种新的酚类糖苷，即6-O-咖啡酰基-β-D-呋喃果糖基-(2→1)-α-D-吡喃葡萄糖苷（1）、1-O-咖啡酰基-β-D-芹菜糖基-(1→6)-β-D-吡喃葡萄糖苷（2）和1-O-对羟基苯甲酰基-β-D-芹菜糖基-(1→6)-β-D-吡喃葡萄糖苷（3）。1-3结构的阐明基于对FABMS以及一维和二维核磁共振谱的解释。在DPPH试验和高铁肌红蛋白试验中，发现化合物1和2作为抗氧化剂具有中等活性。
