[0048] 1.2.1 Preparation of the test solution
[0049] The dried Salvia miltiorrhiza was crushed and passed through a No. 4 sieve to obtain the sample powder. Accurately weigh 1.0000g of the sample powder, put it in a 50ml round bottom flask, add an appropriate amount of ethanol solution, and shake well. Heating to reflux for extraction after weighing. After making up the weight, filter to obtain the test solution.
[0050] 1.2.2 Preparation of reference solution
[0051] Accurately weigh 10.0 mg of high-grade lignin, place it in a 5ml volumetric flask, add ethanol to dissolve, shake well, and obtain the reference substance solution with a concentration of 2.0mg / ml.
[0052] 1.2.3 Chromatographic conditions
[0053] The chromatographic conditions for the determination of high hazy lignin content are: chromatographic column BDS Hypersil C18 (250mm×4.6mm, 5 μm), mobile phase: acetonitrile-0.02% potassium dihydrogen phosphate solution (26-74), detection wavelength 289nm, colu...
Embodiment 1
[0068] Embodiment 1 A kind of response surface method optimizes the extraction process of high hazy lignin in Danshen miltiorrhiza, comprising the following steps:
[0069] (1) After drying the sample of Salvia miltiorrhiza for testing, pulverize it, and pass through a No. 4 sieve to obtain the sample powder;
[0070] (2) The extraction process of high smear lignin in the sample powder is carried out pre-experimentation, and the factors affecting the extraction rate of high smear lignin are ethanol aqueous solution concentration, extraction time, liquid-to-solid ratio and extraction times; and according to the single Factor multi-level experiment, screened out the parameter ranges of ethanol aqueous solution concentration, extraction time, liquid-solid ratio and extraction times;
[0071] (2.1) Ethanol aqueous solution volume concentration parameter range selection
[0072] The single factor experiment of volume concentration of ethanol aqueous solution was carried out at 5 l...
