Embodiment 1

[0016] Extraction method of yew oil: remove the pulp (aril) from fresh yew seeds and elute to obtain 500g of pure yew seeds, bake, dry, crush into 40-60 mesh, treat with microwave equipment for 1-2min, and then put into In the solvent method extractor, the ratio of raw material to solvent is 1:6, heated at 30-35°C, and the dynamic leaching time is 2-3h. Repeat this method for filtering the solution for 3 times, combine and filter the extraction solution, vacuum distillation and concentration to obtain oil . The vacuum process temperature is controlled within 55°C to extract oil. The solvent is recovered and reused to obtain the crude yew oil of the solvent method, which is then subjected to supercritical CO 2 Desolvation, impurity removal, and refining of equipment and equipment, pressure 26mpa, temperature 42°C, CO 2 The flow rate is 20kg / h, the time is 30-35min, the net is placed, and finely filtered to obtain 169.5 grams of yellowish and transparent yew oil, with a yield ...

Abstract

The invention relates to a method for extracting plant oil from plants, in particular to taxus chinensis oil and an extracting method thereof. The extracting method comprises the following steps that seeds of taxus chinensis fruit are taken as raw materials, oil is obtained through extraction by adopting a microwave method and a solvent method, residual solvent odor and impurities are removed through a supercritical CO2 method, standing, refined filtering and refining are performed on a re-extraction product under the low temperature condition, and then the taxus chinensis oil is obtained. According to the method, re-extracting and refining are performed by adopting the microwave-assistant method and the solvent method to be combined with supercritical CO2 technology equipment, and therefore not only is the basic characteristic that the biological activity is not destroyed under the low temperature condition guaranteed, but also the residual solvent odor and the impurities are removed more effectively and the high standard of the green quality is achieved.

Description

technical field [0001] The invention relates to a method for extracting vegetable oil from plants, namely yew oil and its extraction method. Background technique [0002] In the prior art "Changbai Mountain Plant Resources Chronicle", "Handbook of Chemical Separation of Traditional Chinese Medicine", and "Modern Chinese Medicine Pharmacology", yew is a red bean plant and has another name called yew. There are about 11 species in the world, and there are four varieties in my country. Its seeds are used as a diuretic and menstrual medicine in the folk, but it has not been recorded in commonly used traditional Chinese medicine literature. In recent years, paclitaxel, an effective anti-tumor ingredient, has been isolated from the bark, stem, and leaves of various plants of the genus Taxus, which has attracted great attention from scholars and research departments at home and abroad, and has become a research hotspot. From the functional value of the clinical curative effect, th...
