Research Different Processing Methods Of Six Kinds Of Chinese Traditional Medicines And Analyse Thecontent Change Of The Active Components

This paper is composed of three chapters. Chapter I, Research processing methods of severalkinds of Chinese traditional medicines. Chapter II, Determination of mollugin contents in Rubia.cordifolia L and different processed products and determination of amentoflavone contents inSelaginella tamariscina（Beauv.）Spring and different processed products by HPLC. Chapter III,Summarized problem of Chinese traditional medicines precessing.Chapter Ⅰ. Research processing methods of several kinds of Chinese traditionalmedicines.Processing Chinese traditional medicines of R. cordifolia, S. tamariscina, Salvia miltiorrhizaBge, Cassia obtusifolia L, Psoralea corylifolia Land Nelumbo nucifera leave. Production rate ofdifferent precessed products were calculated.Chapter Ⅱ. Determination of active ingredients of two kinds of traditionalChinese medicine by HPLCDetermination of mollugin contents in R.cordifolia and different processed products.TheHPLC system consisted of Purospher star RP-C18column （4.6mm×250mm,5μm） at25℃,MeOH-H₂O-tetrahydropyrane （90:9.3:0.7） mixture as mobile phase, detection wavelength at250nm, flow rate of1.0ml/min. The mollugin contents in R. cordifolia and different processed products separately for0.52%,1.07%and0.66%respectively.Determination of amentoflavone contents in S. tamariscina and different processed products.The HPLC system consisted of Shim-pack VP-ODS column （4.6mm×250mm,5μm） at25℃,MeOH-0.1%phosphoric acid （65:35） mixture as mobile phase, detection wavelength at337nm,flow rate of0.8mL/min. The amentoflavone contents in S. tamariscina and different processedproducts separately for0.84%,1.07%and0.53%respectively.Different processing method produce different effect of active ingredients.Chapter Ⅲ. Summarized problem of Chinese traditional medicines precessing.
