Embodiment 1

[0028] Take 1g each of the medicinal material powders of Compositae plant Patriniae, Patrinaceae plant Patriniae, and Cruciferae plant Patriniae, add methanol 50ml, ultrasonically treat for 30min, filter, and take the filtrate as the test solution; The Patrinia standard medicinal material is used as the reference substance, add methanol 50ml, ultrasonically treat for 30min, filter, and take the filtrate as the reference substance solution. Take 2 μL each of the above-mentioned test solution and reference solution, respectively, and place them on the same silica gel G thin-layer plate, use cyclohexane-ethyl acetate-glacial acetic acid (5:5:0.1) as the developer, develop, and take out , set to view under 365nm ultraviolet light. At the position corresponding to the chromatogram of the reference substance, the Patrinaceae plant Patriniae and the Cruciferae plant Patrinia had no fluorescent spots, and the Patrinaceae plant Patriniae showed blue fluorescent spots of the same color,...

Embodiment 2

[0030] In this example, the Patrinia herba medicinal materials are respectively sourced from Shandong, Jilin, and Hunan.

[0031] Take 4g each of the three kinds of medicinal material powders, add 50ml of n-butanol, ultrasonically treat for 30min, filter, take the filtrate as the test solution; take Patrinia standard medicinal material as the reference substance, add 50ml of n-butanol, ultrasonically treat for 30min, Filter and take the filtrate as the reference solution. Take 10 μL each of the above-mentioned test solution and reference solution, respectively, and spot on the same silica gel G thin-layer plate, use cyclohexane-ethyl acetate-glacial acetic acid (8:5:0.1) as the developer, develop, and take out , set to view under 365nm ultraviolet light. At the position corresponding to the chromatogram of the reference substance, the three Patriniae all showed fluorescent spots of the same color, so it can be determined whether the identified medicinal material is Patriniae ...

Embodiment 3

[0033] In this example, the Patrinia medicinal material in Patrinia Tablets is identified, and the Patrinaria medicinal material used comes from Shandong.

[0034] Prescription: Patrinia 1000g.

[0035]Preparation method: Take Patrinia 1000g, crush it into coarse powder, impregnate it with 60% ethanol for 24 hours, then carry out percolation, collect the percolation liquid, concentrate it into a thick paste below 70°C, add appropriate amount of auxiliary materials, and make granules. Compressed into 1000 tablets, coated with sugar, and ready to serve.

[0036] Take 1 piece of Patrinia Tablets, add 50ml of methanol, put it in ultrasonic treatment for 30 minutes to fully dissolve, filter, take the filtrate as the test solution; take Patrinia standard medicinal material as reference substance, add 50ml of methanol, put it in ultrasonic treatment for 30min, Filtrate, and take the filtrate as the reference solution; according to the prescription and preparation method of Patrinia ...

Abstract

The invention relates to an identification method for herba patriniae medicinal material. The identification method comprises the following steps: respectively extracting a medicinal material to be detected and herba patriniae standard medicinal material, and placing the medicinal materials on a silica gel G thin-layer plate; developing by taking cyclohexane-acetic ether-glacial acetic acid as a developing solvent; and detecting under a 365nm ultraviolet lamp, wherein the medicinal material to be detected and the herba patriniae standard medicinal material display blue-fluorescence spots with the same color at the same position. The identification method for the herba patriniae medicinal material provided by the invention is strong in specificity and good in repeatability, can be used for effectively distinguishing three different types of herba patriniae, and is suitable for identifying the herba patriniae medicinal materials of all sources and identifying whether a finished product containing the herba patriniae medicinal material contains the herba patriniae medicinal material or not.

Description

technical field [0001] The invention relates to a qualitative and identification method of medicinal materials, in particular to a identification method of Patrinia medicinal material. Background technique [0002] Patrinia is a relatively common Chinese herbal medicine with a wide range of clinical applications. Paijiang was first recorded in "Shen Nong's Materia Medica", and has a long history of medicinal use in my country. It is excavated before the flowers bloom in summer, dried in the sun until half-dried, tied into bundles, and then dried in the shade. There are medicinal records in "Tang Materia Medica" and "Compendium of Materia Medica". From the description of herbal medicines in the past dynasties, Patrinia should be the dried whole plant of Patrinia scabiosaefolia Fisch. or Patrinia villosa Juss. Pungent, bitter, cool in nature, return to stomach, large intestine, Liver meridian, heat-clearing and toxic substances removing, dispelling blood stasis and draining ...
