Abstract

The present invention provides a method for detecting the saponinols in sassafras plants or extracts. The method adopts gas chromatography-mass spectrometry to measure sassy phenols in sassafras plants or extracts. The sample tube containing water-removing agent anhydrous magnesium sulfate is used to collect the plants or extracts of S. japonica, add 1-10mL of methanol solution and shake fully for 10-30min, then take 1-2mL of the extraction solution into the chromatographic bottle, seal it quickly, and pass through the gas chromatography. ‑Mass spectrometry analysis, external standard method for quantification; this detection method is suitable for 3,4‑dimethylphenol, 3‑methoxy‑5‑methylphenol, 3‑methoxy 2,5,6-trimethylphenol, 3,5-dihydroxytoluene, 2,5-dihydroxytoluene, 5-methoxy-2,3-xylenol, 2,5-dimethyl Simultaneous detection of ‑1,4‑benzenediol and other dendrols has the advantages of rapidity, accuracy, and simple operation.

Description

technical field [0001] The invention belongs to the technical field of analytical chemistry, and in particular relates to a method specially used for the detection of arboria phenolic substances in arborica plants or extracts. Background technique [0002] Moss ( Evernia furfuraceae ) belongs to Usneaceae ( Usneaceae ) Treeflower ( Ramalina ) plants are mainly distributed in Yunnan, Guizhou and other places. Due to the complex terrain and changeable climate of the place of origin, there are many kinds of tree mosses, and there are clusters of tree flowers ( Ramalina fastigiata ), crack tree flower ( Ramina Minuscula ) and tree flowers ( Ramalina commista ), etc., the surface is mainly gray-green or dark green, and the types and contents of chemical components are different. In industry, the moss extract is obtained by extracting the active ingredients in the moss mainly through hydrocarbon series solvents such as petroleum ether or benzene, and further processing w...
