ethanol-soluble extract
The sum of ethanol extracts under the conditions specified in this section. 4 Principle
Use the gel sample to filter, dry the extract, and weigh 5 Reagents
Ethanol, 95% (volume fraction
Main instruments
Vacuum bottle: capacity 100ml.,
6.2 Pipette: capacity 50ml..
6.3 Surface blood,
6.4 Shanghai paper; medium speed
6.5 Oven: 103℃±2℃.
6.6 Water bath.
6.7 Desiccator.
6.8 Analytical balance: sensitivity 1mg.
7 Sampling
Sampling is carried out according to the method specified in GB/I12729.2. -2008, ISO 2825:
GB/T:12729.10—2008
8 Analysis steps
8.1 Preparation of sample
Prepare sample 8 according to the method specified in GB/T12729.3.2 Sample
Weigh about 2g of sample (8.1) to the nearest 1mg.8.3 Determination
Use 7-ethanol to transfer all the sample to a [0rml.] volumetric flask, add ethanol to the scale, shake every 30 minutes, and then stand for 16 hours, filter, absorb 50 mL of the filtrate and put it into a pre-dried and constant-weighted table III, evaporate to dryness on water, and dry in an oven at 103℃±2℃ for 1 hour, cool in a desiccator, and weigh. Repeat the drying, cooling, and weighing process until the oxygen difference between two consecutive weighings does not exceed 2 mg, and record the final mass. 9. Expression of analytical results
9.1 Calculation method
The alcohol-soluble extract is expressed as mass fraction and the value is expressed as %. Calculate according to (1): 100
X = (ma-m) ×
Alcohol-soluble extract, %;
Mass of alcohol-soluble extract and surface dish, in grams (g); 1—
Mass of surface dish, in grams (g);
--Mass of sample and surface dish, in grams (g); H—Water content of sample, %.
100—
If the repeatability meets the requirements of 9.2, the average value of the measured results is taken as the result and the values ​​are expressed as the last two digits of the minimum effective point. 9.2 Repeatability
The difference between the results of two measurements performed simultaneously or successively by the same analyst shall not exceed 0.20%. 2
