Hypericum perforatum Chinese medicine because of its remarkable pharmacological action and clinical application effect of more and more attention by people. So Chinese medicine extraction technology to extract of hypericum perforatum extract is becoming more and more widely applied. This article mainly from the medicinal value of hypericum perforatum extract, Chinese medicine extraction technology to extract the hypericum perforatum extract principle to the analysis, the traditional Chinese medicine extraction technology in the application of the extracted hypericum perforatum industry.

the basic information,
' Plant name] Hypericum perforatum, alias st John's wort, small leaf grass, thousands of stories.
【 Source 】 Gambogic branch plant st. john's st John's wort
' The resource distribution 】 Shandong, hebei, shanxi, jiangsu, sichuan, guizhou. In slope, road, ridge weeds.
【 Active ingredients 】 All grass double anthracene ketone compounds, st John's wort element, false gold peach element, the original st John's wort. St John's wort element content is lower in the young plant, flowering is higher; Lower in higher in the petals, leaves, stems from the lowest.
【 Quality standard 】 At present, the overseas for hypericum perforatum take material quality standards as: the content of total gold peach, greater than zero. 3%; Extract fingerprint by international standards.

2, extracting method and medicinal use methanol as extraction agent using traditional Chinese medicine extraction technology to extract and filter and filtrate with HCl precipitation, filtration and crystallization purification.
3, Chinese medicine extraction technology to extract the hypericum perforatum extract principle
Chinese medicine extraction technology to extract of hypericum perforatum st John's wort. With ethanol as the extraction agent, the shattering of hypericum perforatum said take a certain amount, dry grass, all get soaking liquid, using the centrifugal force effect of the centrifugal extraction machine for mixing and mass transfer process, the runtime raw material liquid and extraction agent from their inlet into the bottom of the machine, the high-speed rotating drum, two phase liquid into the complex vortex and turbulence state, full mixing and mass transfer. Then, in the rotating drum and fixed at the bottom of the form under the action of self-priming pump, impeller, the mixture after entering the drum drum at the bottom of the center hole inside; In block flow plate under the action of mixed liquid into the state of high speed rotating, dense phase, moving towards the drum wall, while the density of small to the central axis direction, after the separation of two phase out their discharging mouth finally, complete the mass transfer and phase separation process.
