Embodiment 1
[0023] Embodiment 1: the preparation method of smelly goat extract:
[0024] (1) Take the roots, stems and leaves of the stinky goat plant as raw materials, air-dry them naturally, crush them through a 30-mesh sieve, and obtain the stinky goat fine powder;
[0025] (2) Take 426.24g of smelly goat fine powder, add 860ml of 90%-99%V / V ethanol, extract under the action of ultrasonic waves, the ultrasonic frequency is 40KHz, the extraction temperature is 40°C, the extraction time is 40min, and the same volume is replaced Ethanol, repeatedly leached three times, combined three extractions;
[0026] (3) Filter the extract, and recover ethanol from the filtrate under reduced pressure to obtain 16.65 g of ethanol extract;
[0027] (4) Take 4.24g of ethanol extract, add 5ml of hydrochloric acid or tartaric acid of pH 1-3 to dissolve in water, add 25ml of ethyl acetate to extract, extract 5 times, combine ethyl acetate extracts; concentrate under reduced pressure to recover ethyl aceta...
example 2
[0029] Example 2: The drug susceptibility test of stinky goat ethanol extract ethyl acetate acid extract and ethyl acetate alkali extract comprises the following steps:
[0030] (1) Improved Roche culture medium: according to the national standard GB15987-1995, the improved Roche culture was prepared as a blank control;
[0031] (2) Roche medium containing isoniazid: Add isoniazid to the modified Roche medium, and the final concentration of isoniazid in the medium is 0.2 μg / ml, which is used as a negative control;
[0032] (3) Extract-containing Roche medium: After preparing the improved Roche medium base according to the national standard GB15987-1995, add ethanol extract to prepare extract medium, ethyl acetate acid extract medium, ethyl acetate alkali extraction Dilute the amount of the medium extract, the concentration gradient of the ethanol extract is Y1-Y9, a total of 9 concentration gradients, make 10 parallels for each concentration, and store in a -4°C refrigerator a...
