Abstract

Abstract: Twenty-three strains were isolated from soil where ginseng grew. The Panax Notoginseng extract were analyzed by TLC and HPLC. There were nine strains which can converte Panax Notoginseng extract into highly active ginsenoside, among which the TR-20 was the best one. Moreover, the TR-20 can convert Panax Notoginseng extract into ginsenoside Rg₃(190.2 mg/L). The TR-20 was Aspergillus (Aspergillus sp.) with observation of morphology and cultural characteristics.

Key words: Panax Notoginseng, ginsenoside Rg₃, strain screening, strain identification
