Comparison of Four Enzymes Activities in Ginseng from 15 Different Origins

OBJECTIVE To measure the activities of four enzymes in Radix Ginseng from 15 different origins, in order to provide theoretical basis for the appraisal of ginseng. METHODS Neutral buffer solution was adopted to extract the enzyme solution of Radix Ginseng. Use spectrophotometry to test the activities of Superoxide dismutase (SOD), Glutamic-pyruvic transaminase (GPT), Glucose Phosphate Isomerase (GPI) and Fumarase. RESULTS There are little difference of the SOD activities from 15 batch of ginseng samples; the highest GPT activity of Ginseng sample which in Antu county Wanbao town is 2-3 times of other samples. Fumarase activity in Tonghua county Ji’an town, Linjiang city Dongbeichazi town and other 10 samples are significantly lower than the activities in Antu county WanBao town，Fuson county Beigang town and other 5 batch samples. CONCLUSION The activities of SOD, GPT, GPI and Fumarase can be used as the evaluating indicator of species identification of Radix Ginseng.
