A kind of TLC identification method of fried peach kernel and its preparation

Abstract

The invention provides a thin-layer chromatography identification method for Semen Persicae Preparata and its preparations, which is characterized by including the steps of a, preparing a control medicinal material solution, to be specific, taking Semen Persicae control medicinal material powder, adding sodium hydroxide solution, extracting, centrifuging, collecting supernate, adding chloroform for extracting, collecting lower extract and upper solution, extracting in the same way, combining the extracts, drying by evaporating, and adding methanol for dissolving to obtain the control medicinalmaterial solution; b, preparing a test article solution, to be specific, grinding a test article, and preparing the test article solution in the same way as the control medicinal material solution; c, measuring by thin-layer chromatography, to be specific, dropwise adding the control medicinal material solution and the test article solution to a same silica gel G plate, developing with cyclohexane-ethyl acetate as a developer, extracting, airing, spraying 10% ethanol sulfate solution, heating until spots are clear, and inspecting under an ultraviolet light. The method herein is suitable for quickly and effectively distinguishing Semen Persicae Preparata and its preparations, and Semen Persicae, Semen Persicae Preparata and their preparations. The method herein has good operational convenience, high precision, high sensitivity and good stability and has a good application prospect.

Description

technical field [0001] The invention specifically relates to a TLC identification method for fried peach kernels and preparations thereof. Background technique [0002] Peach kernel (Semem Persicae), also known as peach kernel, is the dry mature seed of peach Prunus persica (L.) Bastsch or mountain peach Prunus davidiana (Carr.) Franch. Peach trees are widely planted all over the country. They are picked when the fruit is ripe from June to July. The pulp and shell of the peaches are removed, the seeds are taken out, and dried in the sun for medicinal purposes. Peach kernel contains a variety of nutritional components and biologically active substances, and is a natural medicine with significant clinical efficacy. Its water decoction and extract also have certain antibacterial, analgesic, anti-allergic, anti-tumor effects. [0003] The peach kernels are processed into boiled peach kernels by boiling water, and the dried peach kernels are then made into fried peach kernels b...

AI Technical Summary

Problems solved by technology

The traditional Chinese medicine formula granules of fried peach kernels, peach kernels, and dried peach kernels prepared by modern technology no longer have the shape of decoction pieces, and it is difficult to distinguish them by their shape

In addition, fried peach kernels are different from peach kernels and dried peach kernels, which can easily cause misuse in clinical practice and pose a hidden danger to patients' medication safety.

At the same time, there is no method for effectively distinguishing fried peach kernels from peach kernels, dried peach kernels and their formula granules
