化肥施用对人参品质影响的观察

目的:对人参施用化肥后的重金属及有害元素残留量、人参皂苷含量及人参产量进行观察研究。方法:采用石墨炉原子吸收分光光度法测定铅、镉、铜、镍、铬,原子荧光法测定砷、锑、汞。采用高效液相色谱法测定人参皂苷Rg1、Re、Rb1。结果:与空白相比,正常施肥的人参中重金属元素含量未见明显增加,符合中国药典(2010年版一部)在白芍等7种药材项下对重金属及有害元素的限量要求;正常浓度施肥时,人参总皂苷含量高于高浓度施肥的人参总皂苷含量;人参产量随施肥浓度增加而递增。结论:适量施用化肥,可明显提高人参产量,但在关注人参产量的同时,更应关注其总皂苷的含量。

Effect of Inorganic Fertilizer on Quality of Panax ginseng

Objective: To study the effect of inorganic fertilizer on the heavy metal and harmful element residues,the content of total ginsenoside and yield of ginseng.Methods: Graphite furnace atomic absorption spectrometry was used for determinating the content of lead,cadmium,copper,nickel and chrome atomic fluorescence spectrometry for arsenic,antimony and mercury.The content of ginsenoside Rg1,Re,Rb1 was determined by HPLC.Results: Compared with the blank ginseng,the ginseng in the normal fertilization did not significantly increase the content of heavy metals.The heavy metals and harmful elements of ginseng met the requirement of Chp 2010.Conclusion: Appropriate fertilizer could help the growth of ginseng.Compared with the production,it should focus more on the content of total ginsenoside.
