Problems solved by technology

[0005] Though the identification method of existing this agarwood uses ethanol as extracting solution, avoids the volatilization of ether, but has the following problems: 1, uses ethanol as extracting solution, and ethanol boiling point is higher, causes ultrasonic time shorter, and the information of effective component Extraction is incomplete; 2, use ethyl acetate and acetone as developer, ethyl acetate and acetone are all irritating, have adverse effects on the health of operators; Not good, the chromatographic information is incomplete

Abstract

The invention discloses a method for identifying agarwood. The method comprises the following steps of: S1: preparing a test solution: taking 1g of test agarwood powder, adding 20-30 mL of ethanol solution, performing sonicating for 50-70 min, performing filtering, and diluting the filtrate to a volume of 25mL to prepare the test solution; S2: preparing a reference drug solution and a reference substance solution, wherein the reference drug solution is prepared by taking agilawood medicinal materials with 0.5g to perform the step S1 to prepare the reference drug solution, and the reference substance solution is prepared by taking methanol solution of 6,7-dimethyl-2(2-phenethyl)chromone to prepare the reference substance solution containing 0.05mg in each 1mL; and S3: performing thin layerchromatographic detection to absorb each of three solutions for 5[Mu]L which are respectively dispensed on the same silica gel GF254 thin layer plate, taking the methyl alcohol-glacial acetic acid asa developing solvent to perform development, taking-out and drying, and performing viewing under an ultraviolet lamp and the sunlight. Besides, the method provided by the invention is safe to operate,better in reproducibility and more complete in the chromatography information.

Description

Technical field [0001] The invention relates to the technical field of analysis and testing, and more specifically, it relates to a method for identifying agarwood. Background technique [0002] Agarwood is a kind of wood containing resin from the spice plant white wood incense. It is produced in southern China and Southeast Asia. It is a precious wood and also a precious Chinese medicinal material and spice. Since natural agarwood is slow to form incense and expensive, and artificial agarwood is still in the development stage, it is unable to produce high-quality agarwood on a large scale, so it cannot meet the market demand, so it is not uncommon to fake real or shoddy agarwood. Among them, flavored wood or scented low-priced wood pretends to be high-priced agarwood. [0003] One of the identification methods stipulated in the 2015 edition of "Chinese Pharmacopoeia" is thin layer chromatography. The specific method is: take 0.5g of the powder of this product, add 30ml of ether, ...
