Analysis of chondroitin sulfate content of Cervi Cornu Pantotrichum with different processing methods and different parts

Abstract

The differences and the variations of chondroitin sulfate content in different parts of Cervi Cornu Pantotrichum(CCP) with different processing methods were investigated. The chondroitin sulfate from velvet was extracted by dilute alkali-concentrated salt method. Next， the chondroitin sulfate was digested by chondroitinase ABC.The contents of total chondroitin sulfate and chondroitin sulfate A， B and C in the samples were determined by high performance liquid chromatography(HPLC).The content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP with freeze-drying processing is 14.13，11.99，1.74，0.32 g·kg⁻¹， respectively. The content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP with boiling processing is 10.71，8.97，2.21，1.40 g·kg⁻¹， respectively. The content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP without blood is 12.47，9.47，2.64，0.07 g·kg⁻¹， respectively. And the content of chondroitin sulfate in wax，powder，gauze，bone slices of CCP with blood is 8.22，4.39，0.87，0.28 g·kg⁻¹ respectively. The results indicated that the chondroitin sulfate content in different processing methods was significantly different.The content of chondroitin sulfate in CCP with freeze-drying is higher than that in CCP with boiling processing.The content of chondroitin sulfate in CCP without blood is higher than that in CCP with blood. The chondroitin sulfate content in differerent paris of the velvet with the same processing methods was arranged from high to low as： wax slices， powder， gauze slices， bone slices.
