Method for identifying rhizoma pinelliae and brooklet anemone root

Abstract

The invention provides use of triglochinic acid in identification of medicinal materials, i.e., rhizoma pinelliae and brooklet anemone root. The invention provides a method for identifying the rhizoma pinelliae and the brooklet anemone root. The method comprises the following steps: a. taking the medicinal materials to be detected; b. taking a reference substance, i.e., the triglochinic acid; c. detecting; d. carrying out result judgment, wherein the medicinal material containing the triglochinic acid is the brooklet anemone root, and the medicinal material which does not contain the triglochinic acid is the rhizoma pinelliae. The method can be used for distinguishing whether the rhizoma pinelliae is adulterated with the brooklet anemone root or not by identifying the presence or absence of the triglochinic acid; if containing the triglochinic acid, the rhizoma pinelliae is adulterated with the brooklet anemone root. The identification process is simple, fast and effective, and the method can be used for identifying the brooklet anemone root and distinguishing whether the rhizoma pinelliae is adulterated with the brooklet anemone root or not; after being processed, the brooklet anemone root still can be identified; the method is stable and reliable.

Description

Technical field [0001] The invention relates to a method for identifying pinellia and tiger palm. Background technique [0002] Pinellia is the dry tuber of Pinelliaternata (Thunb.) Breit, a plant of Pinellia genus in the Araceae family. Tiger palm is a dry tuber of Pinelliae Pedatisecta Schott, a plant belonging to the genus Pinelliae of the Araceae family. [0003] There are many counterfeit products of Pinellia ternata, mainly including tiger palm, Araceae, Pinellia ternata, etc. After processing, the appearance of these medicinal materials is very similar to Pinellia pinellia, which is difficult to identify. Unscrupulous vendors often add this to Pinellia Several medicinal materials were illegally sought for profits, which seriously harmed the interests of Pinellia ternata growers and Pinellia decoction pieces production enterprises. At the same time, it also seriously affected the quality, efficacy and medication safety of Pinellia medicinal materials. [0004] At present, tig...

AI Technical Summary

Problems solved by technology

In order to seek profit, there are many traders who processed tiger palms and then screened and polished them. The original sub-tubers have no obvious characteristics and are very similar to pinellia, making it difficult to identify them. If they are processed into decoction pieces, they can hardly be identified by their characteristics.

At present, there are still many problems in the identification of Pinellia and tiger palm. Traditionally, Pinellia is spherical or oval, and generally has no sub-tubers. However, there are cultivation variations in cultivated Pinellia, and some cultivated Pinellia medicinal materials have sub-tubers. Yes, this has caused the identification of Pinellia and Tiger's Palm by the presence or absence of sub-tubers, and there is a problem of inaccurate identification. Some judge Pinellia and Tiger's Palm by the number of sub-tubers (more than 3 are judged as Tiger's Palm) ), this method is still not rigorous enough to achieve the purpose of accurate identification
