Chemical study on Cassiae Semen processing procedure / 中国中药杂志

ABSTRACT

References and our previous experiment showed that the contents of glycosides were significantly decreased，while the contents of aglycones were significantly increased after processing of Cassiae Semen.It may be related to its glycosidases or the heating process. In order to investigate the reasons, high performance liquid chromatographic (HPLC) was used to study the effects of these two factors on contents of Cassiae Semen's main chemical components in processing. The results showed that glycoside hydrolases was present in Cassiae Semen and could rapidly hydrolyze glycosides from Cassiae Semen into aglycones in suitable temperature with sufficient water.However，it didn't show effect on contents change of main constituents in the procedure of Cassiae Semen processing.The reason for content decrease of glycosides and content increase of aglycones in processed Cassiae Semen was glycoside bond cracking to produce corresponding aglycone at high temperature.This study further provides basis for further revealing of the processing mechanism of Cassiae Semen.
