Embodiment Construction

[0050] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0051] see figure 1Shown, the process of diaryl heptane compound separation and preparation method in walnut green husk of the present invention is:

[0052] Step a, rough extraction of walnut green sebum;

[0053] Step a1, processing walnut green skin: take walnut green skin and dry in the shade in a ventilated place until the material becomes brittle, put it in a constant temperature box (40-45° C.) for drying, grind it, pass through an 80-mesh sieve, and put it into a glass container for later use.

[0054] Step a2, methanol water leaching; weigh 3 parts of 20 grams of walnut green peel powder in three 250mL conical flasks in equal amounts, add 200mL of methanol aqueous solution in the ratio of water: methanol 1:4, and stir with a constant temperature magnetic stirrer Homogenize until a suspension is ...

Abstract

The invention relates to a method for separating and preparing diaryl heptane compounds in walnut green seedcase. The method comprises the specific processes as follows: crude extraction of lipid substances in the walnut green seedcase, namely taking the walnut green seedcase as the raw material, performing multistage extraction after auxiliary treatment by use of an ultrasonic microwave extractor, taking the mixed solution of methanol and water in the ratio of 4 to 1 as an extracting agent, performing auxiliary treatment by use of the ultrasonic microwave extractor and then obtaining ethyl acetate extracts by use of MSE; separation by virtue of thin layer chromatography, namely performing extraction separation and comparative analysis on the substances extracted in the step a; collecting and preparing various monomers by use of a high-speed counter current chromatograph; obtaining 6 monomeric substances from a TLC developer, benzene and ethyl acetate in the ratio of 1 to 1 to 1 and comparing the 6 monomeric substances with eight purified products one by one, and detecting that the obtained ethyl acetate extracts are the diaryl heptane compounds by use of an UV method. According to the method, the technique of preparing the diaryl heptane compounds by use of the HSCCC method is simple and easy to operate; in addition, the raw material is cheap and the yield is relatively high, and the extraction ratio of the walnut green seedcase powder is relatively high.

Description

technical field [0001] The invention relates to the field of separation of diaryl heptane compounds, in particular to a method for separation and preparation of diaryl heptane compounds in walnut green husks. Background technique [0002] The extraction of diaryl heptane compounds in the prior art generally includes drying, extract extraction and separation and purification processes. After the obtained components are reacted with different reagents, they are finally mixed to obtain substances containing diaryl heptane compounds. The extraction rate of the diaryl heptane compound extracted by this method is relatively low. [0003] In view of the above-mentioned defects, the author of the present invention has finally obtained this creation through research and practice. Contents of the invention [0004] The object of the present invention is to provide a kind of diaryl heptane compound separation and preparation method in walnut green husk, in order to overcome above-me...
