Problems solved by technology

[0003] The volatile oil recorded in the Pharmacopoeia needs to be extracted with fresh medicinal materials. If it is extracted with dry medicinal materials, the extraction rate will be extremely low; Therefore, in the prior art, the extraction of the herbaceous coral liquid extract mostly adopts boiling water to extract the dry medicinal materials, so as to ensure that the active ingredients in the dried medicinal materials are fully dissolved, but in the state of high temperature for a long time, it is easy to cause isoxazine The oxidation reaction of active ingredients such as pyridinium will affect th

Abstract

The invention provides a method for extracting effective ingredients of raw and fresh sarcandra glabra herbal medicine. The raw and fresh sarcandra glabra not exceeding two days is used as a raw material, under specific extraction conditions, the extraction of a liquid extract and the extraction of volatile oil are carried out simultaneously to obtain volatile oil and an extract liquid, and the extract liquid is further concentrated and purified to obtain the liquid extract. The raw and fresh medicinal material is used for extracting both the liquid extract and the volatile oil, so as to ensure full utilization of the sarcandra glabra medicinal material and avoid waste. The yield and quality of the liquid extract and the volatile oil are guaranteed by the extraction method.

Description

technical field [0001] The invention relates to the field of extracting traditional Chinese medicinal materials, in particular to a method for extracting effective components of fresh medicinal materials such as coral coral. Background technique [0002] Grass coral is a perennial evergreen subshrub of Chestnut orchidaceae. The traditional Chinese medicine name is Zhongjiefeng, commonly known as Manshanxiang, Guanyin tea, Jiujie tea, elderberry, etc. The whole plant can be used as medicine, with bitter, pungent, flat nature, antibacterial and anti-inflammatory , expelling wind and dampness, promoting blood circulation and relieving pain. From the perspective of medicinal ingredients, grass coral is rich in volatile oils, esters, phenols, tannins, flavonoids, cyanogenic glycosides, coumarins, lactones and other substances. Among them, isoxazinidine can activate human immunity and enhance resistance. The ability of disease, rosmarinic acid has anti-oxidation, anti-depression,...
