摘要： We measured the diversity of soil fungi and bacteria in 10- ginseng producing areas (BS, KM, LX, QJ, WS, XSBN, XC, YS, GX, GZ) in China. The correlation between soil microorganisms and ginsenoside content of P. notoginseng was analyzed to understand the effects of soil microorganisms in different areas on the accumulation of saponins and to explore the relationship between the soil microorganisms and saponins of P. notoginseng in these 10-habitats. The content of Notoginsenoside R-1, Ginsenoside Rg(1), Ginsenoside Re, Ginsenoside Rb-1 and Ginsenoside Rd in P. notoginseng were determined. The correlation analysis of P. notoginseng from different habitats was done by redundancy analysis (RDA). The results showed that the high content of ginsenoside in P. notoginseng was positively correlated with Plectosphaerella and Tetracladium among fungi and Sphingobium, Novosphingobium and Allorhizobium - Neorhizobium - Parrhizobium - Rhizobium among bacteria, while negatively correlated with Mortierella (fungi) and Arthrobacter (bacteria). These 7-kinds of soil microorganisms are important biological factors affecting the accumulation of saponins in P. notoginseng. Thus theoretically we may control the quality of P. notoginseng by regulating the soil microorganisms.
