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 the quality of the extracted liquid extract; and for the extraction of volatile oil, raw water distillation is usually used for 8-10h. After the grass coral is no longer able to extract liquid extract
[0004] However, with the gradual increase in the demand for the extracts of Herba Coralus in the market, the price of Herba Corales herbal medicines has also gradually increased. Only extracting volatile oil from fresh medicinal materials or only extracting liquid extracts from dried medicinal materials makes the value of Herba Corales raw materials unsatisfactory. be fully utilized, resulting in serious waste

Embodiment 1

[0024] A method for extracting effective components of grass coral fresh medicinal materials, comprising the following steps:

[0025] (1) Pre-extraction treatment: remove the sundries from the fresh coral grass that has been collected for two days, clean it, cut it into 1 inch long pieces, and set aside;

[0026] (2) Extraction for the first time and preparation of volatile oil: Put the grass coral cut in the step (1) into the extraction tank, add water of 4 times the weight of the grass coral; connect and open the condenser, storage tank and oil-water separator, raise the temperature of the extraction tank to 86°C, keep warm and extract for 110 minutes, collect the volatile oil of Coralia praecox at the oil-water separator, and collect the first extract in the extraction tank into a container, and keep Coral in the extraction tank;

[0027] (3) The second extraction: add water twice the weight of Grass Coral to the extraction tank, heat to 91°C, keep the heat for extraction...

Embodiment 2

[0030] A method for extracting effective components of grass coral fresh medicinal materials, comprising the following steps:

[0031] (1) Pre-extraction treatment: Remove the sundries from the fresh coral grass that has been collected for two days, clean it, cut it into 1.5 inch long pieces, and set aside;

[0032] (2) Extraction for the first time and preparation of volatile oil: Put the grass coral cut in the step (1) into the extraction tank, add water of 4.5 times the weight of the grass coral; connect and open the condenser, storage tank and oil-water separator, raise the temperature of the extraction tank to 90°C, keep the heat for extraction for 100 minutes, collect the volatile oil of Coralia praecox at the oil-water separator, and collect the first extraction liquid in the extraction tank into a container, and keep Coral in the extraction tank;

[0033] (3) The second extraction: add water of 2.5 times the weight of Grass Coral to the extraction tank, heat to 93°C, ...

Embodiment 3

[0036] A method for extracting effective components of grass coral fresh medicinal materials, comprising the following steps:

[0037] (1) Pre-extraction treatment: remove the sundries from the fresh coral grass that has been collected for two days, clean it, cut it into 2-inch long pieces, and set aside;

[0038] (2) Extraction for the first time and preparation of volatile oil: Put the grass coral cut in the step (1) into the extraction tank, add water of 5 times the weight of the grass coral; connect and open the condenser, Storage tank and oil-water separator, raise the temperature of the extraction tank to 95°C, heat-preserve and extract for 90 minutes, collect the volatile oil from the oil-water separator, and collect the first extraction liquid in the extraction tank into a container, and keep the grass coral in the extraction tank;

[0039] (3) Second extraction: add water 3 times the weight of Grass Coral to the extraction tank, heat to 95°C, keep warm and extract fo...

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,...
