Embodiment 1
[0508] Example 1: Using liquid chromatography to measure the fingerprints of red ginseng or ginseng and Ophiopogon japonicus as the main component characteristics:
[0509] (1) Preparation of the test solution: accurately weigh an appropriate amount of the freeze-dried powder to be tested, add water to make a solution containing 50mg per 1ml, filter it with a 0.45μm microporous membrane, and take the additional filtrate as the test solution ;
[0510] (2) Preparation of reference solution: accurately weigh ginsenoside Rg 1 An appropriate amount, add methanol to make a solution containing 0.3mg per 1ml, as a reference solution;
[0511] (3) Chromatographic conditions: The chromatographic column uses octadecylsilane bonded silica gel as the filler; mobile phase A is 0.05mol / L potassium dihydrogen phosphate solution, mobile phase B is acetonitrile-water 80:20, gradient elution, solvent The ratio is from 0 minutes to 5 minutes, the ratio of mobile phase B is 25%, from 5 minutes to 40 ...
Embodiment 2
[0518] Example 2: Using liquid chromatography to measure the fingerprint spectrum with the main component characteristics of Schisandra:
[0519] (1) Preparation of the test solution: accurately weigh an appropriate amount of the freeze-dried powder to be tested, add water to make a solution containing 50mg per 1ml, filter it with a 0.45μm microporous membrane, and take the additional filtrate as the test solution ;
[0520] (2) Preparation of reference solution: accurately weigh an appropriate amount of Schizandrin A reference substance, add water to make a solution containing 0.1 mg per 1 ml, as the reference solution;
[0521] (3) Chromatographic conditions: The chromatographic column uses octadecylsilane bonded silica gel as the filler; the mobile phase is methanol-water, gradient elution, the solvent ratio is from 0 minutes to 6 minutes, the methanol ratio is 68%, from 6 From 8 minutes to 8 minutes, the proportion of methanol rose from 68% to 76%, from 8 minutes to 10 minutes...
Embodiment 3
[0528] Example 3: Using liquid chromatography to determine the fingerprints of red ginseng or ginseng and Ophiopogon japonicus as main component characteristics:
[0529] (1) Preparation of the test solution: accurately weigh an appropriate amount of the freeze-dried powder to be tested, add methanol to make a solution containing 50mg per 1ml, filter it with a 0.45μm microporous membrane, and take the subsequent filtrate as the test product Solution
[0530] (2) Preparation of reference solution: accurately weigh ginsenoside Rb 1 Appropriate amount, add ethanol to make a solution containing 0.3mg per 1ml, as a reference solution;
[0531] (3) Chromatographic conditions: The chromatographic column uses octadecylsilane bonded silica gel as the filler; mobile phase A is 0.05mol / L sodium dihydrogen phosphate solution, mobile phase B is acetonitrile-water 85:15, gradient elution, solvent The proportion is from 0 minutes to 4 minutes, the proportion of mobile phase B is 22%, from 4 minu...
