[The Component Analysis of Petroleum Ether Extract in Scutellariae barbatae,Hedyotis diffusa and the Herb Pair and the Investigation of Anti-Endometrial Cancer Cells Activity].

Objective: To investigate the chemical components and the activity of anti-endometrial cancer cells of the petroleum ether extract in Scutellariae barbatae and Hedyotis diffusa and the herb pair.

Methods: Main composition analysis and identification were determined by the GC-MS technology combined with Kovats retention index( KI). Activity of anti-endometrial cancer cells was researched by MTT assay.

Results: Unsaturated fatty acid,esters,sterol and other compounds in Scutellariae barbatae,Hedyotis diffusa and the herb pair were identified by GC-MS. Hedyotis diffusa and the herb pair contained more anthraquinones which distinguished from Scutellariae barbatae. The IC50 values for HEC-1A cells of petroleum ether extract in Scutellariae barbatae and Hedyotis diffusa and the herb pair were 275. 204 μg / m L,105. 826 μg / m L,148. 645 μg / m L. The IC50 values for Ishikawa cells of petroleum ether extract in Scutellariae barbatae and Hedyotis diffusa and the herb pair are 189. 114 μg / m L,77. 974 μg / m L,137. 999 μg / m L.

Conclusion: Petroleum ether extract in Scutellariac barbatae and Hedyotis diffusa and the herb pair has inhibition effect on the proliferation of HEC-1A and Ishikawa cells,the Hedyotis diffusa has the strongest activity of anti-endometrial cancer. It is speculated that the strongest activity could be related to the higher content of anthraquinones.
