Abstract

The invention discloses a method for extracting polyphenol substance from new variety oil peony seed shells. The method comprises the following steps that extraction of herbaceous peony seed shell powder is carried out by adopting assistance of ultrasonic wave and ethanol solution, extracting solution is concentrated and dried, polyphenol content is measured, three factors of ethanol content, liquid and materials ratio and extracting time are selected to carry out a single factor experiment, a three-factor and three-level experimental design is carried out according to a Box-Benhnken design principle, an optimum extracting process parameter is determined; and extract liquor is obtained by using the extracting process parameter, nonionic surface active agent and assisted extracting agent are added in the extract liquor, and vortex and centrifugation are carried out. According to the method for extracting the polyphenol substance from the new variety oil peony seed shells, a method of combining ultrasonic wave extracting and cloud point extracting is used, compared with an optimized method for extracting ultrasonic wave polyphenol substance, the method for extracting the polyphenol substance from the new variety oil peony seed shells has the characteristics that extracting ratio is high up to 1.5 times, extracting condition is gentle, the extracting agent is friendly to the environment, and extracting cost is low. Waste oil peony seed shells are recycled, not only the waste oil peony seed shells can be made profitable, but also environmental pollution problems can be greatlysolved.

Description

technical field [0001] The invention belongs to the field of extracting plant components, and in particular relates to a method for extracting polyphenols from the shell of a new variety of oily peony seed. Background technique [0002] Peony is a traditional Chinese medicine used to treat various diseases. It can be divided into red peony and white peony, both of which use roots as medicine. The white peony does not set seeds or the seeds are very small; Low. In industry, the effective active ingredients are generally extracted from the rhizome of Paeoniae Radix. Youshao is a new variety bred by crossing Chishao and Hangshao for more than 20 years. It not only has a well-developed root system, but also has a breakthrough in seed production. The seed yield of Paeoniae suffolius over 4 years is not less than 450 catties / mu. Even more than 800 catties per mu. After experimental analysis, peony seed oil contains more than 95% unsaturated fatty acids beneficial to the human bo...
