ObjectiveTo determine the content of gallic acid in Xinjiang Punica granatum L.by HPLC.

目的测定新疆石榴皮中没食子酸的含量。

By means of molecular mechanics and molecular dynamics methods, the binding modes and inte-ractions between newly found matrix melalloproteinases inhibitors, Pyrogallic acid and Myricetin, and MMP-7 were investigated in the present study.

采用分子力学和分子动力学方法，考察了MMPs抑制剂、焦性没食子酸和杨梅黄酮与MMP-7的具体结合方式以及相互作用的情况。

The calculated results show that the binding affinity between Myricetin and MMP-7 is higher than that between Pyrogallic acid and MMP-7 when they bind to MMP-7, thus Myricetin is more potent on MMP-7 than Pyrogallic acid. This is in agreement with the inhibitory activity order from experiments.

研究结果表明，在与MMP-7结合时，杨梅黄酮比焦性没食子酸具有更高的亲合性，因此杨梅黄酮对MMP-7有更好的效能，这与实验测得的活性顺序相符。

Test solution of pyrogallic acid was prepared by adding formic acid as antionxidative stabilizer, thus the measuring instability due to the oxidability of pyrogallic acid was overcome.
