标题：The Establishment of the Method of Cell Biochromatograpy and Analysis of the Active Ingredients from TongQiaoHuoXue Decoction Acting on the Neurocytes
摘要：A novel strategy for screening active components in traditional Chinese medicines (TCM) using living cells and HPLC and GC analysis are proposed. The hypothesis is that when cells are incubated with the extract of Tongqiao Huoxue Decoction (TQHXD), a famous ancient prescription in TCM, the potential active components in the TQHXD should selectively combine with the cells, and the cell-combining components would be detectable in the extract of denatured cells. The identities of the cell-combining components could be determined by HPLC and GC analysis. Using the proposed approach, two characteristic active ingredients binding to the membrane of the PC12 cells are indicated. In the fingerprint of HPLC, there are two characteristic peaks. One active ingredient with its retention time was at around 70 min had been identified as muscone by HPLC, GC, which came from Moschus herb, the other active ingredient may come from the Allium fistulosum , its structure needs further research. Also, the protective effect of muscone on PC12 cells induced by Oxygen and glucose deprivation (OGD) had been explored. These results show that the pretreatment with muscone on PC12 cells observably increased cell viability, reduced the release of lactate dehydrogenase (LDH) and cell apoptosis. Combined with the pharmacodynamic study of muscone on neuroprotective effect, it could be identified as one of the effective components in TQHXD.
