Problems solved by technology

The original standard of Liuwei Mingmu Pills only has the identification of berberine hydrochloride and the content determination of berberine hydrochloride, but there is no measurement item of iron content in the iron powder of Fangzhong Junyao, and the large amount of gallic acid contained in Fang Zhongjun medicine, myrobalan, and emblical has not been tested. content determination, so the safety and effectiveness of the preparation cannot be guaranteed

Embodiment 1

[0132] Embodiment 1: Quality inspection of Liuwei Mingmu Pills

[0133] A. Determination of iron content:

[0134] Take 0.5g of Liuwei Mingmu pill powder, weigh it accurately, place the crucible containing the sample on the electric furnace and burn it slowly (to avoid burning, swelling, overflowing), until the test sample is completely carbonized, black, and no longer Smoke and let cool to room temperature. Add an appropriate amount of 1ml of sulfuric acid dropwise to make the charcoal completely wet, continue to heat until the steam is removed and the white smoke is exhausted, blaze at 600°C for 4 hours, let cool, wash with 50ml of concentrated hydrochloric acid and move to a 250ml Erlenmeyer flask with a stopper , heat and dissolve at about 65°C for 4 hours (shake occasionally to avoid boiling), transfer the solution to a 250ml volumetric flask after cooling, wash the container with a small amount of water, merge the washing solution into the same volumetric flask, add wat...

Embodiment 2

[0143] Example 2: Quality detection of Liuwei Mingmu Granules

[0144] A. Determination of iron content:

[0145] Take 0.5g of Liuwei Mingmu granule powder, weigh it accurately, put the crucible containing the sample on the electric furnace and burn it slowly (to avoid burning, swelling, overflowing), until the test sample is completely carbonized, black, and no longer Smoke and let cool to room temperature. Add an appropriate amount of 1ml of sulfuric acid dropwise to make the charcoal completely wet, continue to heat until the steam is removed and the white smoke is exhausted, blaze at 600°C for 4 hours, let cool, wash with 50ml of concentrated hydrochloric acid and move to a 250ml Erlenmeyer flask with a stopper , heat and dissolve at about 65°C for 4 hours (shake occasionally to avoid boiling), transfer the solution to a 250ml volumetric flask after cooling, wash the container with a small amount of water, merge the washing solution into the same volumetric flask, add wat...

Embodiment 3

[0155] Embodiment 3: Liuwei Mingmu capsule quality inspection

[0156] A. Determination of iron content:

[0157] Take 0.5g of Liuwei Mingmu Capsule content powder, weigh it accurately, place the crucible containing the sample on the electric furnace and burn it slowly (to avoid burning, swelling, overflowing), until the test sample is completely carbonized, black, and When no longer smoking, let cool to room temperature. Add an appropriate amount of 1ml of sulfuric acid dropwise to make the charcoal completely wet, continue to heat until the steam is removed and the white smoke is exhausted, blaze at 600°C for 4 hours, let cool, wash with 50ml of concentrated hydrochloric acid and move to a 250ml Erlenmeyer flask with a stopper , heat and dissolve at about 65°C for 4 hours (shake occasionally to avoid boiling), transfer the solution to a 250ml volumetric flask after cooling, wash the container with a small amount of water, merge the washing solution into the same volumetric ...

Abstract

The invention discloses a quality testing method for a Liuwei Mingmu preparation of a Tibetan medicine composition. The preparation comprises various preparations prepared by prepared ferrous powder, cortex berberidis, carum carvi, fructus chebulae, fructus terminaliae billericae and phyllanthus emblica according to a conventional pharmaceutical method. The quality testing method comprises a content testing method of the ferrous powder and / or a content testing method of gallic acid. According to the quality testing method for the Liuwei Mingmu preparation of the Tibetan medicine composition, the iron content in the Liuwei Mingmu tablets of the Tibetan medicine composition is detected at the first time, the iron content in the Liuwei Mingmu tablets of the Tibetan medicine composition is tested through a mercury-free potassium dichromate titration method which is convenient, quick and accurate to use and operate, and the active constituent gallic acid in the Liuwei Mingmu tablets of the Tibetan medicine composition is quantitatively tested through a high performance liquid chromatography. With the adoption of the method provided by the invention, the content testing method of the iron and the content testing method of the Liuwei Mingmu tablets of the Tibetan medicine composition is increased, the quality of the Liuwei Mingmu preparation of the Tibetan medicine composition can be ensured, and the preparation can be guaranteed to be safe, effective, stable and controllable in quality.

Description

technical field [0001] The invention relates to a quality detection method of a Tibetan medicine composition preparation, in particular to a quality detection method of a Tibetan medicine composition Liuwei Mingmu preparation. Background technique [0002] At present, due to changes in living environment, work pressure, and eating habits, many eye diseases are at a high incidence. The popularity of the Internet and incorrect eye habits have made the number of people with visual fatigue more and more powerful, with an annual growth rate of 25%. Tibetan medicine believes that the occurrence of eye diseases is caused by the dysfunction of Chiba hyperactivity (inflammation of the liver) and the dysfunction of Weiminglong, which can see the Chiba function and convey the light of the body. According to this theory, initiated by the Northwest Plateau Institute of Biology, Qinghai Institute of Tibetan Medicine, Jinhe Tibetan Medicine and other units, combined with traditional techn...
