Two new tetralone derivatives, named cyclopalosides A (1) and B (2), were isolated from the leaves of Cyclocarya paliurus by column chromatography on silica gel, reversed-phase C silica gel and preparative HPLC. Their chemical structures were established on the basis of extensive analyses of spectroscopic data. Their structural characteristic is tetralone glycoside with a caffeoyl unit. The antioxidant activities of compound 1 were evaluated by using hydroxyl, superoxide anion, and DPPH radical scavenging assay.
通过硅胶柱色谱、反相C硅胶柱色谱和制备型高效液相色谱，从青钱柳的叶子中分离出两种新的四氢萘酮衍生物，命名为环杷苷A（1）和环杷苷B（2）。通过对光谱数据的广泛分析确定了它们的化学结构。它们的结构特征是带有咖啡酰基单元的四氢萘酮糖苷。通过羟基自由基、超氧阴离子自由基和DPPH自由基清除试验评估了化合物1的抗氧化活性。
