First, bezoar is different:

1, Tongrentang Angong Niuhuang Pill red iron box is artificial bezoar.

2, Tongrentang Angong Niuhuang Pill Qingmu Box is natural bezoar.

Second, the price is different:

1, Tongrentang Angong Niuhuang Pill red tin box 200 yuan.

2. Tongrentang Angong Niuhuang Pills, 400 yuan.

It must be that natural bezoar has a better effect, and Angong Niuhuang Pill has a better effect on patients with coma, high fever and noisy throat after stroke.

Extended data:

1. Take a small amount of this product, mix it with clean water, and apply it on nails, which can dye nails yellow, commonly known as "hanging nails".

2. Put a little of this product in a test tube and add 3ml of the following reagents respectively. Slightly hot, with color reaction: add glacial acetic acid to show green, and after cooling, carefully add equal volume of sulfuric acid. The lower layer is colorless, the upper layer is green, and the junction between the two layers is red ring. (check the sterol reaction) add sulfuric acid to show green; Add nitric acid to show red; Adding ammonia water is yellow-brown.

3. Take 0.2g of powder, add 1ml hydrochloric acid, then add 20ml of diethyl ether for oscillating extraction, let stand, separate the diethyl ether solution, filter it, put it in a separatory funnel, add 20ml of barium hydroxide saturated solution, shake well, and yellow precipitate will be produced. The water layer and precipitate were separated and removed, and the ether layer was washed twice with saturated barium hydroxide solution, each time with 10ml.

Separate the ether layer, filter, evaporate to dryness, add chloroform 1ml to the residue to dissolve it, add acetic anhydride 1ml and 2 drops of sulfuric acid, shake well, and let it stand for 10 minute, which is green.

4, take a small amount of powder, add chloroform 1ml and shake well, add 2 drops of sulfuric acid and 30% hydrogen peroxide solution, shake well, that is, show red. (Check bilirubin)

5. Take 0. 1g powder, add 4 ml of 60% acetic acid, grind and filter, take 1ml filtrate, add 1ml new 1% sugar aldehyde (newly distilled to almost colorless) solution and 65438+ sulfuric acid solution (take 50ml sulfuric acid and add water)

6. Take the ethanol extract of this product as the test solution, and the ethanol solution of cholic acid and deoxycholic acid as the reference solution. Dot the two solutions on the same silica gel G thin-layer plate, develop with chloroform-ether = glacial acetic acid (2: 2: 1), spray 10% aluminum phosphate ethanol solution, and bake at 105℃ 10 minute for color development. The liquid chromatography of the sample shows the same blue spots at the positions corresponding to the chromatogram of the reference substance.

7. Take 10mg powder, add 20ml chloroform for ultrasonic treatment for 30 minutes, filter, evaporate the filtrate, and add 1ml ethanol to dissolve the residue as the test solution. Cholic acid and deoxycholic acid were used as control, and ethanol was added to make a mixed solution containing 2mg per 65,438+0 ml as control solution.

Absorb 2μl of the above two solutions, spot them on the same silica gel G thin-layer plate, spread them with isooctane-ethyl acetate-glacial acetic acid (15: 7: 5) as developing agent, take them out and dry them, spray them with 10% sulfuric acid ethanol solution, and bake them at 105℃ for about 5 minutes, and place them in an ultraviolet lamp.
