Problems solved by technology

At present, the industrial production of gallic acid at home and abroad mainly uses gallnuts as raw materials, and gallic acid is prepared by acid hydrolysis, alkali hydrolysis, fermentation and enzymatic hydrolysis, but all of them are pure. The corrosion is very serious; the alkaline hydrolysis process is more cumbersome and consumes a lot of energy; although the efficiency of the fermentation method and the enzymatic method has been improved, the production cost has also been greatly increased, the requirements for personnel are high, and some organic impurities have been introduced

Embodiment 1

[0052] 1. Preparation of rose pomace extract

[0053] Get 9kg of rose pomace, add 11 times the quality of enzymolysis solution (enzymolysis solution is 2W / V% cellulase, 1W / V% hemicellulase, 0.5W / V% pectinase, 0.5W / V% Isolated enzyme, pH 6.5; the above enzyme was purchased from Henan Zhengxing Food Additive Co., Ltd.), soaked for 40 minutes, and extracted 3 times by crushing tissue, 3 minutes each time, filtered with eight layers of gauze, added a certain amount of filter residue and extracted 3 times again, each 3 minutes, so repeated three times. The filtrates were combined three times and concentrated into an extract with a multi-stage flash evaporator.

[0054] 2. Organic solvent gradient extraction

[0055] Take 55 grams of rose slag extract, add 350 mL of water to disperse, and make the specific gravity about 1.2. Ultrasound for 20 minutes to help dissolve, followed by extraction with ethyl acetate, ethyl acetate:95% ethanol=6:2, after the extraction, spin off the resi...

Embodiment 2

[0081] 1. The extraction method of the active part of rose dregs, the steps are as follows:

[0082] (1) Preparation of rose dregs extract: take rose dregs, add 11 times the mass of enzymatic hydrolysis solution, soak for 55 minutes, extract 3 times by tissue breaking method, 3 minutes each time, filter with eight layers of gauze, combine the filtrate, and The multi-stage flash evaporator recovers the solvent and concentrates it into a paste. The enzymolysis liquid is 2W / V% cellulase, 1W / V% hemicellulase, 0.5W / V% pectinase, 0.5W / V% isolated enzyme, and the pH is 6.5.

[0083] (2) Gradient extraction of rose dregs extract, separating organic phase and water phase, and obtaining active site DRFR-A and active site DRFR-B from the organic phase: take the rose dregs extract obtained in step (1), add water to make Suspend to make the specific gravity at 1.2, and extract with ethyl acetate solution and ethyl acetate-ethanol mixed solution respectively. After the extraction is comple...

Abstract

The invention belongs to the field of chemical technologies and relates to an extraction method for active parts of a rose flower residue and an application of the extraction method. The method comprises the following steps of (1) preparing rose flower residue extract; (2) extracting the rose flower residue extract in a gradient manner, separating an organic phase from a water phase, and obtaining an active part DRFR (Damask Rose Flower Residue)-A and an active part DRFR-B from the organic phase; (3) separating a sediment from the water phase in the step (2) and purifying to prepare an active part DRFR-C; and (4) carrying out suction filtration on the water phase in the step (2), recovering filtrate and purifying to prepare an active part DRFR-D. The rose flower residue generated after essential oil is extracted is taken as a raw material, organic solvent extraction is carried out after tissues are crushed and extracted, and tyrosinase inhibition and antioxidant activity screening are carried out on extracted various parts to separate out a monomer or a substance with high biological activity, so that a theoretical basis is laid for comprehensive utilization of rose flowers.

Description

technical field [0001] The invention belongs to the field of chemical technology, and relates to a method for extracting active parts of rose dregs and an application thereof. Background technique [0002] Damask rose (Rosa Damascena), commonly known as Damask rose, also known as Turkic rose, Rosaceae Rosa, is a classical garden rose, bushy shrub plant, native to Syria, widely planted in France since the 14th century, and Damascena rose is planted in Bulgaria It is also the main rose variety recognized in the world as a high-quality rose variety. The essential oil produced is the top grade of roses, so it is widely planted to extract rose essential oil. [0003] Roses have a long history of cultivation in my country, and are currently planted all over the country. Pingyin, Shandong is the largest rose planting base in China, and is rich in rose resources. In recent years, Damascena roses used to extract essential oils have been successively introduced in various places. A...
