Abstract:
In order to study the rule that different growth stages of ginseng saponins in different stem leaf number ginseng how to change. Born three stems, two stems and single stem ginseng of three to four years old as the research object and take ginseng saponins as testing indexes to compare the variation. Acquisition set different stem number and different growth stages of ginseng in Ji’an. The total content of ginsenosides was determined by using ultraviolet spectrophotometry and the contents of 7 kinds of mono ginsenosides was measured by using HPLC, and then the variation was compared. ①Ginseng saponins content increased with the growth years. In different birth period, born in three or four years, ginseng in the red fruits had the highest contents of total ginseng saponins, 4.46%, 4.94%, 4.97%, 6.69%, 5.00% respectively. ②The ginsenosides contents in different stem ginseng and double stem ginseng were higher than those of in single stem ginseng and three stem the ginseng. ③There were different monomers in the root of ginsenosides in different period. Overall, at different growth stages, the monomer saponins had the highest content of Rb1 in red fruits. Rb1 was 1.035 mg/g in double stem of four years had; and Rd content was the lowest in wilt period. Rd content was the lowest 0.105 mg/g in single stem of three years. The monomer saponins contents in different stem ginseng and double stem ginseng were higher than those of in single stem ginseng and three stem the ginseng. The ginseng sponins content had close relation with growth period and the number of stem. It suggested that ginseng should do double stem process in plant period, and ginseng should be harvested in the last of red fruits.
