根腐对三七的皂苷含量影响

目的:对比分析根腐三七与正常三七中总皂苷及R1、Rg1、Rb1三种单体的含量,为根腐三七的质量评价及利用提供依据.方法:同田对比正常三七、根腐三七及不同腐烂程度三七的皂苷含量与单体成分,用HPLC法测定单体皂苷含量,大孔吸附树脂吸附比色法测定总皂苷含量.结果:三七根腐后比正常三七总皂苷含量平均降低了30.88%,R1、Rg1、Rb1三种单体平均含量分别降低了25.53%、11.26%、17.82%.结论:三七的皂苷含量随根部腐烂程度的增加而减少,根部腐烂对R1、Rg1、Rb1三种单体皂苷的比例无显著影响.

Effects of root rot on saponin content in Panax notoginseng

Objective:To provide the proof for the quality evaluate and the utilization of root rot Panax notoginseng,the contents of saponins were analyzed, such as ginsenoside Rb 1,ginsenoside Rg 1 and notoginsenoside R 1 in the rotted and normal roots.Method:The saponin contents were contrasted with samples in same field and different rotted degree Panax notoginseng.The single saponin was determined by HPLC and the total saponin was determined by macro resin absorbing-colorimetric method.Result:The total saponin was decreased 30.88% in sick root than in normal root. The contents of three single saponin R 1,Rg 1,Rb 1 were decreased 25.53%,11.26% and 17.82%, respectively. Conclusion:The saponin contents was declined with the degree of rot. The rot had no effect on the proportion of the three single saponin.
