Problems solved by technology

[0003] Shimanzi is a commonly used traditional Chinese medicine of the Yao nationality. At present, only the identification of traits is used as the basis for identification, lack of quantitative indicators and means, and the method is very superficial. Not only lacks specificity, but also it is difficult to accurately evaluate the authenticity and quality of the medicinal materials

Embodiment 2

[0033] Example 2. This example is to explore the method of Example 1. Take 3 g of lime powder (passed through a No. 4 sieve), add methanol for ultrasonic extraction, add chloroform and shake for 2 times, combine the organic phases, and evaporate to dryness , The residue was dissolved by adding 1 mL of methanol and used as the test solution. Take an appropriate amount of ferulyl tyramide reference substance and add methanol to make a solution containing 1 mg per 1 mL as a reference substance solution. The above two solutions were spotted on the same silica gel G thin-layer plate, using chloroform-methanol (9:1) as the developing agent, unfolded and dried, and then placed under ultraviolet light (254nm) for inspection. The results showed that the test solution had a dark background and could not be clearly identified.

[0034] Therefore, in step (1), the test product is purified. After the sample is extracted with methanol, the sample is extracted twice with petroleum ether by sh...

Abstract

The present invention discloses a thin-layer chromatography rapid identification method for Pothos chinensis, and the method uses based thin-layer chromatography technology to identify feruloyltyramine content in Pothos chinensis. The rapid determination is simple and accurate, has high sensitivity, good precision, good stability, and is very conducive to application in rapid quality control of Pothos chinensis medicinal material in the pharmaceutical process.

Description

Technical field [0001] The present invention relates to a fast identification method of citrus seeds by thin layer chromatography, and a fast determination method of ferulyl tyramide in citrus seeds based on thin layer chromatography technology, belonging to the field of quality detection of traditional Chinese medicines. Background technique [0002] Lipograss is the dry whole plant of Pothos chinensis (Raf.) Merr., a plant of the genus Litacarpus in the Araceae family. It is also known as gourd drill, grapefruit maple, stone centipede, climbing cliff incense, etc. It is used to treat traumatic injuries and rheumatic bone pain in the Yao area One of the most commonly used drugs. However, because the Yao nationality has no written language, the inheritance and dissemination of the Yao nationality’s medical knowledge is completely transmitted by word of mouth, resulting in the confusion of the same name and the same name in the use of the Yao medicine, and the safety and effective...
