Objective: To investigate effects of different processing methods on heavy metals and effective components in cut of Notoginseng Radix et Rhizoma. Method: Cut of Notoginseng Radix et Rhizoma was treated by rinsing
soaking and polishing.Contents of As
Cd
Pb and Hg were determined by inductively coupled plasma mass spectrometry (ICP-MS).HPLC was used to analyze contents of ginsenoside Rg1
ginsenoside Rb1 and notoginsenoside R1 with mobile phase of acetonitrile-0.05% phosphoric acid for gradient elution
flow rate of 1.6 mL·min-1 and detection wavelength of 203 nm. Result: Rinsing was the best way of all.After rinsing
contents of As
Cd
Pb
Hg decreased by 1.24%
58.33%
51.06%
2.70%
respectively.However
contents of As and Cd increased by polishing.The content of total saponins in different processing methods ranked by rinsing > polishing > untreated > soaking. Conclusion: Rinsing can both decrease contents of heavy metals and maintain the content of saponins
so it can be used as a processing method for Notoginseng Radix et Rhizoma.
