Embodiment Construction

[0009] This specific embodiment adopts following technical scheme: its extraction process is: one, adopt supercritical CO 2 The fluid extraction method extracts the proanthocyanidins in the camellia oleifera shell for 10 to 30 minutes; 2. At the same time, the proanthocyanidins are filtered and adsorbed for 10 to 20 minutes by flocculation clarification technology and resin adsorption separation technology; 3. Dry by spray drying process, the drying time is 20 ~ 30 minutes, the extraction rate is 1 ~ 3%, and the proanthocyanidins with a purity of 94% ~ 96% can be obtained.

[0010] This embodiment adopts supercritical CO 2 The fluid extraction method is carried out by using the relationship between the dissolving ability of supercritical fluid and its density, that is, using the influence of pressure and temperature on the dissolving ability of supercritical fluid. In the supercritical state, the supercritical fluid is contacted with the substance to be separated, so that it ...

Abstract

The invention relates to the technical field of medicine processing and discloses a proanthocyanidin extraction process from camellia seed hull. The extraction process includes: 1) a step of extracting proanthocyanidin in the camellia seed hull for 10-30 min by adoption of a supercritical CO2 fluid extraction method; 2) a step of simultaneously filtering and adsorbing the proanthocyanidin for 10-20 min by a flocculation clarification technology and a resin adsorption separation technology; and 3) drying for 20-30 min through a spraying drying process, and therefore the proanthocyanidin with a purity of 94-96% and an extraction yield of 1-3% can be obtained. The extraction process has characteristics of high extraction speed of the proanthocyanidin from the camellia seed hull, high efficiency and less energy consumption. Operation parameters can be controlled easily, thus effectively guaranteeing the stable product quality.

Description

Technical field: [0001] The invention relates to the technical field of pharmaceutical processing, in particular to a supercritical CO 2 Extraction-flocculation extraction and purification process of proanthocyanidins in camellia oleifera seed shell. Background technique: [0002] Extracting active ingredients from natural animals and plants is of great significance to improving resource utilization and social production and living standards. Camellia oleifera resources in my country are very rich. According to statistics, there are about 55 million mu of camellia oleifera in the country, with an annual output of 1.5 million tons of oil. After refining camellia oil, more than 10 million tons of camellia oleifera seed shells will be brought. If these large amounts of remaining tea seed shells can be utilized through light chemical biotechnology, huge economic benefits will be produced. Studies have shown that there are proanthocyanidins with high development and utiliza...
