Abstract:

The aim was to provide theoretical basis for the cultivation and optimization of ginseng. Adopt neutral buffer solution to extract the enzyme solution of Radix Ginseng. The activities of Malate Dehydrogenase (MDH), Lactate Dehydrogenase (LDH), Alcohol Dehydrogenase (ADH) and Glucose-6-phosphate Dehydrogenase (G6PDH) were detected by spectrophotometry, and compared. The clustering analysis was performed using the software SPSS13.0 to system for 15 batch sample. There were obvious differences of the activities dehydrogenase of ginseng from different origin. The activities of four dehydrogenases from the same origin were basically same. In Antu County Wanbao Town, MDH, LDH and G6PDH had the highest activities, 124.58 U/(g?Fw), 129.88 U/(g?Fw) and 109.84 U/(g?Fw) respectively. The four kinds of enzymes activity of two origins in Heilongjiang Province were generally low. The sample was divided into four categories. The activities of MDH, LDH, ADH and G6PDH could provide theoretical basis for the cultivation and optimization of ginseng.
