Abstract

The invention provides a preparation method of a roxburgh rose extract. The preparation method of the roxburgh rose extract comprises the following steps: step 1, pulverizing roxburgh rose leaves andadding the pulverized roxburgh rose leaves in water for extraction, and filtering to obtain a roxburgh rose water extraction solution and roxburgh rose leaf filter residues; step 2, adding the roxburgh rose leaf filter residues in ethanol, and extracting and separating to obtain a roxburgh rose leaf extract; step 3, dissolving sodium ascorbate and potassium metabisulfite in water, adding roxburghrose fruits, pulverizing to obtain pulp, and filtering to obtain roxburgh rose juice and roxburgh rose pomace; step 4, adding roxburgh rose pomace in ethanol and extracting, and filtering to obtain aroxburgh rose fruit alcohol extract; and step 5, mixing and condensing the roxburgh rose leaf water extracting solution, the roxburgh rose juice and the roxburgh rose fruit alcohol extract, and mixingthe concentrated solution into the roxburgh rose leaf extract to obtain the roxburgh rose extract. According to the preparation method of the roxburgh rose extract, the roxburgh rose is prepared intothe extract for the first time, effective constituents of the roxburgh rose is retained to a maximum extent, the additional value of the roxburgh rose is increased, and intensive processing productsof the roxburgh rose are enriched.

Description

technical field [0001] The invention relates to the extraction field of roxburghii, in particular to a preparation method of roxburghii extract. Background technique [0002] Rosa roxburghii is a wild plant of the family Rosaceae, which is a unique wild resource in the Yunnan-Guizhou Plateau, with Guizhou as the main production area. The whole plant of Rosa roxburghii has extremely high medicinal value and edible value, and its pharmacological effects are closely related to the chemical components contained in it. Many studies on the pharmacological effects of Rosa roxburghii use the juice of Rosa roxburghii or preparations with the juice as the main component. [0003] Studies have shown that Rosa roxburghii fresh fruit is rich in vitamins, polyphenols, flavonoids, organic acids, polysaccharides, amino acids and trace elements. The organic acids contained in Rosa roxburghii are mainly malic acid, lactic acid, tartaric acid, citric acid, oxalic acid and succinic acid; the h...
