Abstract

The invention discloses an identification method of guava leaf processed products, which can effectively solve the identification problem of the guava leaf processed products, and the solution is realized by the following steps: firstly, preparing test solutions; secondly, preparing reference drug solutions of the guava leaf processed products; finally, determining by a thin-layer chromatography.The identification method is simple, rapid, stable, reliable, accurate, specific, and has good separation effect of spots in the thin-layer chromatography, and is effectively used for the identification of the guava leaf processed products.

Description

technical field [0001] The invention relates to the field of identification of traditional Chinese medicines, in particular to an identification method of processed guava leaves. Background technique [0002] Guava leaves are the leaves of myrtaceae plant guava (Psidium guajava L.). It is distributed or cultivated in Fujian, Taiwan, Guangdong, Guangxi, Sichuan and Yunnan. It has the effects of drying dampness and invigorating the spleen, clearing away heat and detoxifying. It is often used to treat diarrhea and abdominal pain, indigestion and abdominal distension, gingival swelling and pain, rheumatic arthralgia, eczema and eczema, furuncle swelling, swelling and pain from bruises, traumatic bleeding, and snake and insect bites. [0003] After the guava leaves are processed, the efficacy of the medicine is enhanced, the toxicity or side effects are reduced, and it is convenient for storage and administration. [0004] There is existing record about the quality standard of...
