为研究农田人参皂苷积累规律,确定农田栽参适宜采收期.利用超高效液相色谱法,使用WatersBEH-C18柱(2.1 mmn×50 mm,1.7μm)分析柱,流动相为乙腈-0.4％甲酸水溶液,梯度洗脱,流速为0.5 mL/min,柱温35℃,检测波长为203 nm.结果标明:9月21日采收5年生人参平均单支重量77.88 g;9月21日采收6年生人参皂苷Rgl、Re、Rf、Rbl、Ro、Re、Rb2、Rb3和Rd含量分别为0.78％、0.48％、0.24％、1.32％、0.54％、0.71、0.76％、0.15％和0.35％;9种人参皂苷含量为5.34％.人参有效成分积累最大值出现在9月21日采收的5年生人参.总之本研究为农田栽参适宜采收期提供科学依据.“,”The purpose of this study was to find the ginsenosides accumulation law of farmland planting ginseng and determine the suitable harvest time.In this research,the UPLC method was conducted on a waters BEH-C18 analytical column (2.1 mm×50 mm,1.7 μ,m) with the mobile phase of acetonitrile-0.4％ methanoic acid solutioby gradient elution at a flow rate of 0.5 mL/min,where the column temperature was maintained at 35℃ and the detection wave length was 203 nm.The results showed the average weight of 5 year-old ginseng harvested in 21th September was 77.88 g.For 6-year-old raw run ginseng harvested in 21 th September,the contents of ginsenosides Rgl,Re,Rf,Rbl,Ro,Rc,Rb2,Rb3 and Rd were 0.78％,0.48％,0.24％,1.32％,0.54％,0.71％,0.76％,0.15％ and 0.35％,respectively.The total content of 9 kinds of ginsenosides was 5.34％.The highest concentration of active ingredients in ginseng occurred on 5-year-old ginseng harvested in 21th September.In conclusion this research provided a scientific basis for the suitable harvesting time of the field.
