| titleOfInvention | Method for measuring contents of main components in rhodiola rosea medicinal material |
| abstract | The invention relates to a method for measuring contents of gallic acid, salidroside, tyrosol and p-coumaric acid in a rhodiola rosea medicinal material. The method comprises the steps of preparing a gallic acid reference substance solution, a salidroside reference substance solution, a tyrosol reference substance solution, a p-coumaric acid reference substance solution and a rhodiola rosea medicinal material sample solution respectively; taking PhenomenexLunna C18 (4.6mmx250mm, 5 microns) as a chromatographic column and taking acetonitrile-0.3% glacial acetic acid solution as a flowing phase to measure the reference substance solutions and the sample solution under column temperature of 40 DEG C, a volume flow of 0.7mL/min and wavelengths of 275nm and 308nm, recording a chromatogram and calculating the contents of gallic acid, salidroside, tyrosol and p-coumaric acid in the rhodiola rosea sample solution. |
