Abstract

The invention relates to the technical field of pharmaceutical analysis and specifically relates to a thin-layer identification method for septemlobate kalopanax bark formula granules. The thin-layer identification method comprises the following steps: taking 0.5g granules and grinding; adding methyl alcohol and then performing ultrasonic processing; filtering; adding hydrochloric acid into filtrate and then heating and refluxing for 1 hour; drying by distillation; adding 1ml methyl alcohol into residue, dissolving and taking as a test solution; taking a defined amount of oleanolic acid and hederagenin reference substance; adding the methyl alcohol and preparing into a reference substance solution; respectively sucking 3mu l of the two solutions and respectively dipping the solutions to a same silica gel G thin layer plate; taking cyclohexane-ethyl acetate-glacial acetic acid as a developing solvent; developing, taking out and drying in the air; spraying ethanol sulfate solution; heating at 105 DEG C till the spot developing is clear; placing under an ultraviolet lamp for inspecting; in a test chromatography, developing the fluorescent spots in same color on the position corresponding to the reference substance chromatography. The result thin-layer chromatography spot is clear and the repeatability is excellent.

Description

technical field [0001] The invention relates to the technical field of drug analysis, in particular to a thin-layer identification method for Chuantongpi formula granules. Background technique [0002] Chuantong bark is the dry bark of Araliaceae thorny catalpa, or thorny catalpa. The bark can be harvested throughout the year, peeled off the bark, and dried in the sun, which can dispel rheumatism, dredge collaterals, and relieve pain. For rheumatoid arthritis. Waist and knee pain; externally used for bruises. It often grows in mountainous sparse forests and is produced in Anhui, Hubei, Hunan or Guangxi. [0003] There are few domestic reports on the related research of pauliatrina paulifolia. At present, there is no TLC identification item for pauliania palismania in the current pharmacopoeia and provincial standards of Chinese medicinal materials, and the TLC identification item for palynonia palisana formula granules is also lacking, and only a few research and developm...
