[0041] The samples of Panax notoginseng powder collected in the market include raw products and processed products, as shown in Table 1. It has been identified as the dry root and rhi...

Embodiment 2 10

[0062] The microscopic identification of embodiment 2 Panax notoginseng powder

[0063] The notoginseng powder sample is the same as in Example 1.

[0064] Take an appropriate amount of Panax notoginseng powder, permeabilize it with chloral hydrate, add glycerol dropwise, mount the slices, and observe the microscopic features such as catheters and resin channels under a microscope. Mount the slices directly with glycerol, and observe the microscopic features of the starch granules under a microscope.

[0065] The tubes and resin ducts of these 12 samples of Panax notoginseng powder have no obvious difference microscopically, so it is impossible to judge their authenticity.

Embodiment 3 10

[0066] Embodiment 3 Panax notoginseng powder extract is measured

[0067] Get 12 groups of test product Notoginseng powder 2g respectively, accurately weighed, put in a 100ml Erlenmeyer flask, and press the hot soak method under the 2015 edition "Chinese Pharmacopoeia" according to the alcohol-soluble extract method (Appendix X A) For the determination, methanol was used as solvent. Precisely add 50ml of anhydrous methanol, seal it tightly, weigh it, let it stand for 1 hour, connect the reflux condenser, heat to boiling, and keep boiling slightly for 1 hour. After cooling down, remove the Erlenmeyer flask, seal it tightly, weigh again, make up for the lost weight with anhydrous methanol, shake well, filter with a dry filter, accurately measure 25ml of the filtrate, and place it in a container that has been dried to constant weight. In an evaporating dish, evaporate to dryness on a water bath, dry at 105°C for 3 hours, cool in a desiccator for 30 minutes, and weigh quickly and...

Abstract

The invention provides a method for quickly identifying the notoginseng powder, which can quickly and accurately identify genuine notoginseng powder and common counterfeit notoginseng powder by observing the reaction of insoluble matter in the notoginseng powder.

Description

technical field [0001] The invention relates to a rapid identification method of Panax notoginseng powder, which belongs to the field of traditional Chinese medicines. Background technique [0002] Panax notoginseng is the dry root and rhizome of Panax notoginseng (Burk.) F.H.Chen. The original medicinal materials of Panax notoginseng are easy to identify, but most of the commercially available Panax notoginseng is a crushed product, which is easy to be adulterated and difficult to identify. In the market, there are many counterfeit products of Panax notoginseng powder, and the prices are also uneven. Adulteration and shoddy products are common. It is common to see counterfeit notoginseng leaves mixed with notoginseng powder. After extraction, notoginseng powder is sold as a fake, and the growth period of notoginseng powder that does not meet the pharmacopoeia standards is sold. Therefore, how to verify the authenticity of notoginseng powder For identification, how to judg...
