不同净制工艺对三七质量的影响

Effects of Different Clean-Processing on Quality of Radix Notoginseng

目的:分析不同净制工艺对三七主根、剪口、筋条质量的影响,为建立该药材合理的净制工艺提供参考。方法:选取超声清洗5 min,超声清洗10 min,流水冲洗,锉刀打磨和清水浸泡5种清洗方式对三七进行净制处理,并参照药典的方法对其外观性状、水分、总灰分、醇溶性浸出物及有效成分含量进行测定,将各参数结合方差分析等多元统计分析进行比较。结果:超声清洗5 min更适合根和筋条有效成分的保留,超声清洗5 min和锉刀打磨2种净制方式均适用于剪口;醇溶性浸出物和人参皂苷Rg1,Rb1和三七皂苷R1含量均为剪口>主根>筋条。结论:超声清洗作为一种新型的净制方法,适用于三七所有药用部位的清洗。

Objective:To analyze the effects of different clean-processing on the quality of taproot,scissor and tendon of Radix Notoginseng and provide reference for better clean-processing of Radix Notoginseng.Methods:According to the present condition of clean equipment,we developed five kinds of cleaning methods to process the Radix Notoginseng,including ultrasonic cleaning 5 min,ultrasonic cleaning 10 min,rinsing,filing,and water immersion in this study.Aim to confirm whether the quality of the Radix Notoginseng changed after the processing using the method we developed,we systematically analyzed the exterior characters,water content,total ash and the effective ingredients extracted by the methanol,saponins content of Radix Notoginseng,all of which were also quality control standard described in the Pharmacopoeia of the People′s Republic of China(2015 edition).Results:Ultrasonic cleaning for 5 min were more suitable for the retention of roots and rootlets,both of filing and ultrasonic cleaning 5 min were good at rhizomes.The contents of methanol soluble extracts and saponins content of Radix Notoginseng were all according with rhizomes>roots>rootlets.Conclusion:This result suggested that dividing the Radix Notoginseng into different tissue and using the corresponding cleaning method are the effective way to keep Radix Notoginseng clean with a higher quality in the clean-processing.
