Problems solved by technology

[0004] The by-product of rosemary ointment is a kind of oily paste by-product containing high content of ursolic acid obtained in the process of producing ursolic acid, which can play a significant role in antioxidant and antibacterial, and is widely used in the food field. Its water solubility is very poor, so the application of rosemary ointment by-products is mainly limited to oily products

Embodiment 1

[0044] 1: Select 100kg of by-products of rosemary ointment with 12.6% ursolic acid content, add 1000kg of 70% ethanol solution and stir to dissolve, after stirring for half an hour, use fast filter paper (filter diameter 25μm) to discard insoluble components.

[0045] 2: Add 6kg Tween-80 to the filtrate obtained in step 1, stir slightly to dissolve it completely, then slowly add 120kg polyethylene glycol-400. After complete addition, stir for 30 minutes to dissolve completely.

[0046] 3: Pass the solution obtained in step 2 through a horizontal centrifuge equipment, control the centrifuge speed to 3000r / min, and the centrifugate directly enters the ultrafiltration system. The designed maximum flow rate of the ultrafiltration system is 200L / h, and the control outflow speed is 70L / min, the molecular weight cut-off of the ultrafiltration membrane is 100kDa, substances exceeding this molecular weight will be effectively intercepted, and this part of molecules is prone to precipi...

Abstract

The invention discloses a method for producing ursolic acid emulsion by using a rosemary oil paste byproduct as a raw material, and the method comprises the following steps: (1) treatment of the rosemary oil paste byproduct: selecting the rosemary oil paste byproduct containing a certain amount of ursolic acid, adding a certain amount of ethanol solution, dissolving, filtering, and drying to obtain the rosemary oil paste byproduct; (2) mutual dissolution of rosemary oil paste by-products: adding a certain amount of tween-80 into the filtrate as a surfactant, and adding a polyethylene glycol-400 solution which is relative to the weight of the rosemary oil paste by-products, so that the tween-80 and the rosemary oil paste by-products in the solution are mutually dissolved; (3) ultrafiltration and impurity removal: performing centrifuging, filtering centrifugate through a ceramic membrane ultrafiltration system to separate most macromolecular impurities; (4) concentration: concentrating filtrate to 1 / 5 of the original volume, filtering, and filtering residual ethanol through nanofiltration to obtain an ursolic acid emulsion product. The method is short in process and low in cost, andthe prepared ursolic acid emulsion product is good in water solubility.

Description

technical field [0001] The invention belongs to the field of plant extraction, and specifically discloses a method for producing ursolic acid emulsion by using rosemary ointment as a raw material. Background technique [0002] Rosemary (Rosmarinus officinalis L.) is an evergreen shrub of the Labiatea family. It is native to the Mediterranean region and is currently cultivated in Xinjiang, Yunnan, Guizhou and other places in China. Warm in nature and pungent in taste, the main part used is the leaves, which have the functions of invigorating the stomach, refreshing the mind, calming the nerves, etc. It has certain therapeutic effects on nervous, digestive and respiratory diseases, and is also a traditional spice and food additive. [0003] Rosemary is rich in various antioxidant components and has a strong antioxidant capacity. It is currently recognized as a plant with high-efficiency antioxidant effects. The Institute of Botany, Chinese Academy of Sciences successfully int...
