Embodiment

[0034] 1. Experimental reagents

[0035] Methanol is chromatographically pure, from Fisher Corporation of the United States;

[0036] Ultrapure water was prepared by laboratory ELGA PURELAB Classic-UVF pure water machine, which was purchased from the UK;

[0037] All other reagents were commercially available domestic analytical grade.

[0038] 2. Experimental samples

[0039] Patent sample: Ethyl acetate extract of Caulis chinensis prepared in Example 1 of CN201210209139.8. The specific preparation method is as follows: the medicinal material sample is crushed into coarse powder, and 500 grams of coarse powder is taken, soaked in petroleum ether for 1 day, and then percolated Extract until the color of the extract is light (or 5 times the amount of medicinal materials), recover petroleum ether to obtain petroleum ether extract; evaporate the residue to remove petroleum ether, moisten it with 80% ethanol, and then use 3 times the amount of 80% ethanol to reflux and extract t...

Abstract

The invention relates to a detection method for ethyl acetate extract of paederia scandens. The method is carried out through UPLC (Ultra Performance Liquid Chromatography) / Q-TOF-MS (Quantity-Time of Flight-Mass Spectrometry). A UPLC map disclosed by the invention has great stability and repeatability, and the study provides a means to evaluate the quality of the ethyl acetate extract of the paederia scandens, and is beneficial to the further development of quality monitoring of the ethyl acetate extract of the paederia scandens.

Description

technical field [0001] The invention relates to a detection method of traditional Chinese medicine, in particular to a detection method of the ethyl acetate extract of Caulis chinensis. Background technique [0002] Jishiteng, the name of traditional Chinese medicine. It is the whole herb and roots of the perennial herbaceous vine of the Rubiaceae genus Cauliflower. "Compendium Supplements" says: "Rub the leaves and smell it, and there is a foul smell. I don't know what its correct name is. Because of its smell, people call it stinky vine." The righteousness lies in its stench. In September-October after planting, except for the seedlings, the above-ground parts can be harvested every year and dried in the sun or in the sun. Or dig the roots in autumn, wash them, slice them, and dry them for medicinal purposes. It has the effects of expelling wind and dampness, digestion and accumulation, detoxification and swelling, promoting blood circulation and relieving pain. [00...
