Objection : To study the yield and quality of Salvia miltiorrhiza bge.var.alba inctroducted from Shandong Laiwu

planted in Hunan province. Method : Salvia miltiorrhiza bge and S. miltiorrhiza bge.var.alba were planted samely

and the number

size

weight of two plant's radix were counted.The content of tanshinone ⅡA and salvianolic acid B were determined by high performance liquid chromatography(HPLC)

microscopic characters of transverse section of radix were studied. Result :The content of chemical constituent accorded with the standard of pharmacopoeia

the yield of S. miltiorrhiza bge.var.alba was higher significiently. Microscopic characters of transverse section of two plants showed significient difference. Conclusion : S. miltiorrhiza bge.var.alba as a high qulity S. miltiorrhiza bge resource was fitted to plant in Hunan province for future development.
