Effects of Five Allelochemicals on Ginsenosides in Ginseng Seedling Roots
五种化感物质对人参幼根皂苷含量的影响

The effects of diisobutyl succinate, 1,2-benzenedicarboxylic acid bis (2-methylpropyl) ester, palmitic acid, and 2,2-bis(4-Hydroxyphenyl) propane on ginsenosides in ginseng seedling roots at 1 mg·L-1, 0.1 mg·L-1 and 0.01 mg·L-1 were assessed using the colorimetric method. Results showed that allelochemicals could affect the concentration of ginsenosides in ginseng seedling roots. Phenolic acid chemicals could noticeably reduce the content of ginsenosides, when its concentration reached a given level. It is concluded that allelochemicals in the root exudates not only affect the seed germination, seedling growth, and the physiological and biochemical indicators, but also have a bearing on the concentration of ginsengsides.
