Abstract

The invention provides a thin-layer identification method of rhizoma phragmitis and preparations thereof, which comprises the following steps: preparing a reference medicinal material solution: adding a reference medicinal material of rhizoma phragmitis into water, decocting, taking decoction, drying, and then adding methanol for ultrasonic treatment to prepare the reference medicinal material solution; preparing a test solution, namely adding reed rhizome decoction pieces to be detected into water, decocting, taking decoction liquid, drying the decoction liquid, and then adding methanol for ultrasonic treatment to prepare the decoction piece test solution; or respectively adding to-be-detected reed rhizome standard decoction freeze-dried powder and / or to-be-detected reed rhizome formula granules into methanol, and carrying out ultrasonic treatment to prepare a standard decoction test solution and / or a formula granule test solution; and identifying, namely respectively sucking the reference medicinal material solution and the test solution, dripping on a thin-layer plate, developing by using a developing solvent, and then developing. According to the method, a color developing agent does not need to be used, color development can be directly carried out under the wavelength of 365 nm, and the method is simple.

Description

technical field [0001] The invention relates to the field of identification of traditional Chinese medicinal materials, in particular to a thin-layer identification method for reed rhizome and its preparation. Background technique [0002] Reed root is the fresh or dry rhizome of Phragmites communis Trin. Can be excavated throughout the year, remove the buds, fibrous roots and membranous leaves, and use fresh or dried. Cough due to heat, lung abscess and vomiting of pus, stomach heat and vomiting, hot stranguria and astringent pain. [0003] Thin-layer chromatography, also known as thin-plate chromatography, is a kind of chromatography and is a very important experimental technique for rapid separation and qualitative analysis of small amounts of substances. There are few domestic reports on the TLC identification of reed rhizome. The main reason is that there are TLC identification methods for reed rhizome in the Chinese Pharmacopoeia and the provincial traditional Chines...
