Production method of modified oviductus ranae

Abstract

The invention provides a production method of modified oviductus ranae, which comprises the steps of oviposition in purified water, fertilized egg treatment, freeze drying, oil-egg separation and the like, and the obtained oviductus ranae is the modified oviductus ranae. According to the method, pure and impurity-free oviductus ranae without sex hormones is extracted under the condition of not needing excessive external intervention according to the embryonic development characteristics of Rana amurensis, and the obtained oviductus ranae does not have the characteristics of form, component content, medicine property and the like of traditional oviductus ranae, but is similar to the traditional oviductus ranae in water absorption expansion rate and smell. The protein content is inversely proportional to the time before the embryonic development is completed, and the contents of polypeptides, oligopeptides and amino acids are directly proportional to the time before the embryonic development is completed. The method does not damage the health and normal oviposition and survival of the wood frogs, prolongs the utilization cycle of the wood frogs, upgrades the traditional oil extraction by killing the frogs into oil extraction by raising the frogs, and has important significance for protecting the precious germplasm resource of the wood frogs in China, orderly developing and reasonably utilizing the wood frogs and benefiting the society.

Description

technical field [0001] The invention relates to a production method of wood frog oil, in particular to a production method of modified wood frog oil. Background technique [0002] Rana oil is a traditional medicine and health food in my country. It has various medicinal and health effects such as anti-fatigue and regulating human endocrine (Gaofeng et al., 2005). The main component of Rana oil is protein. In the 1930s, Japanese scholars analyzed its components and found that the protein content accounts for more than 50% of the total amount of Rana oil. Rana oil has a complete range of amino acids and is rich in content. At the same time, it contains a variety of unsaturated fatty acids and esters, and is also rich in vitamins and trace elements (Han Tiesuo et al., 2008). [0003] The most well-known medicinal effect of Rana oil is "nourishing yin", which means it has a special nourishing effect on women. Many domestic scholars have therefore also detected the sex steroid...

Problems solved by technology

Sex hormones function through corresponding receptors, and have targeted affinity for some receptors, which is manifested as stimulation and affinity for some existing tumor cells, resulting in accelerated tumor proliferation, which also limits The consumption and promotion of Rana oil has had a direct impact on the development and application of its products

[0005] At the same time, the existing method of extracting oil from forest frogs is to kill frogs to obtain oil. Each forest frog needs to be cultivated for at least 3 years before it can be hunted and killed for oil, which cannot be repeated and is not sustainable.
