Method for determining component content in Evodia rutaecarpa and processed products thereof

Abstract

The invention discloses a method for determining the component content in Evodia rutaecarpa and processed products thereof. The method for determining the component content in Evodia rutaecarpa and the processed products thereof comprises the following steps of: S1, preparation of the processed products of evodia rutaecarpa; and S2, preparation of a test solution: taking about 0.3g of powders of raw Evodia rutaecarpa and different processed products of Evodia rutaecarpa, weighing accurately, placing in a conical flask with a stopper, adding 75ml of 70% ethanol precisely, soaking for 1h, performing ultrasonic treatment for 40min, placing to cool, weighing again, making up for weight loss with 70% ethanol, shaking well, filtering, taking subsequent filtrate, and passing through a 0.22 [Mu]mmicrofiltration membrane. According to the invention, the component content in Evodia rutaecarpa and different processed products thereof is determined simultaneously, so that the linear relation of the component is good; the RSD values of the precision, stability and repeatability are less than 2%; the average sample recovery rate is 98.25% to 104.41%; part components of Evodia rutaecarpa in different years change with the increase of the palcing time; different processing methods have different effects on the chemical composition content of Evodia rutaecarpa; and the invention provides relevant reference basis for the quality research of Evodia rutaecarpa and different processed products.

Description

technical field [0001] The invention relates to the technical field of Evodia rutaecarpa, in particular to a method for determining the content of components in Evodia rutaecarpa and its processed products. Background technique [0002] Evodia rutaecarpa is the dry and near-ripe fruit of Evodia rutaecarpa, Evodia rutaecarpa or Evodia rutaeceae of Rutaceae. It was first recorded in "Shen Nong's Materia Medica", "Where chamaejasma, citrus aurantium, orange peel, Pinellia, ephedra, and Evodia rutaecarpa all want to get old for a long time, the rest only need new essence." Evodia rutaecarpa mainly contains alkaloids, limonin, Flavonoids, phenolic acids, polysaccharides and volatile oils and other components. The processing methods mainly include purification, ginger, salt, coptis and licorice. [0003] At present, the processing methods of Evodia rutacarpa mostly rely on local experience, and there is still a lack of standardized processing technology guidance, and no unified ...
