Priliminary Test of Chemical Components for Veronicastrum Caulopterum(Hance)Yamazaki

Objective：To study the chemical constituents of Veronicastrum caulopterum（Hance）Yamazaki by priliminary test. Methods：The extracted mixture of Veronicastrum caulopterum （Hance）Yamazaki from petroleum ether,purified water and 95% ethanol were studied by test tube method. The chemical constituents of Veronicastrum eaulopterum（Hanee）Ya- mazaki was primarily demonstrated by precipitation reaction or color reaction with various indicator. Results：The priliminary test indicated that Veronicastrum caulopterum（Hance）Yamazaki may contain chemical constituents such as flavonoid, phenols organic acid, glucide, coumarin. Conclusion：The results of priliminary test provide evidence for further study of the chemical compositions and biological activities of the Veronieastrum caulopterum（Hance）Yamazaki.
