title: [Influence of different original processing methods on quality of Salvia Miltiorrhizae Radix et Rhizoma from Shandong].
abstract: In this paper the contents of rosmarinic acid, salvianolic acid B, crytotanshinone, tanshinone II(A) in samples of different original processed Salvia Miltiorrhizae Radix et Rhizoma were determined by HPLC. Different processing methods have varied influences on four active ingredients in Salvia Miltiorrhizae Radix et Rhizoma. Sun-drying reduced the content of crytotanshinone, tanshi-none II(A) and rosmarinic acid, integralsamples were better than those cut into segments. Oven dry method had great influence on water--soluble ingredients, high temperature (80-100 degrees C) could easily cause big loss of rosmarinic acid and salvianolic acid B. The role of traditional processing method "fahan: was complicated, the content of rosmarinic acid decreased, crytotanshinone and tanshinone II(A) increased, and salvianolic acid B showed no difference after "fahan". Drying in the shade and oven dry under low temperatrure (40-60 degrees C) were all effective to keep active ingredients of Salvia Miltiorrhizae Radix et Rhizoma, and, there was no difference between integral samples and samples cut into segments. Therefore, considering comprehensively the content of active ingredients in Salvia Miltiorrhizae Radix et Rhizoma, and processing costing etc., shade-drying or oven dry underlow temperature (40-60 degrees C) should be the most suitable original processing method.
