Abstract

The invention discloses a preparation method of Chinese chestnut peel extract containing ceramide. The preparation method comprises the following steps: S1, taking Chinese chestnut peel raw materialsand crushing; adding an extracting solvent and extracting; decompressing extracting filtrate to recycle the solvent; concentrating in vacuum to obtain concentrated extract; S2, adding an alkaline solution into the extract and carrying out hydrolysis to obtain hydrolysate; S3, carrying out macroporous resin column separation on the hydrolysate and washing a resin column with water until flowing-outliquid is colorless; eluting and collecting an eluting solution; decompressing and concentrating; drying to obtain Chinese chestnut peel crude extract; S4, dissolving the Chinese chestnut peel crudeextract with alcohol and eluting on the column; carrying out thin layer chromatography detection; collecting fractions by sections; combining the fractions and concentrating and drying to obtain the Chinese chestnut peel extract. According to the preparation method disclosed by the invention, ceramide substances are extracted from Chinese chestnut peels; the raw materials are easy to obtain and are green and environmentally friendly; a preparation technology is simple and easy to control; the quality of a product is stable and the production cost is low; the content of the ceramide in the obtained extract can reach 95 percent.

Description

technical field [0001] The invention relates to the technical field of extraction and separation of natural products, in particular to a method for preparing a ceramide-containing chestnut peel extract. Background technique [0002] Chestnut has the reputation of "the king of dried fruits", and it is also called "ginseng fruit" abroad. According to scientific experiments, chestnuts are rich in nutrients, and the fruit contains up to 70.1% sugar and starch, and 7% protein. In addition, it also contains fat, calcium, phosphorus, iron, carotene, thiamine, riboflavin, niacin, various vitamins and trace elements, especially the content of vitamin C, B1 and carotene is higher than that of ordinary dried fruits. high. Chinese medicine believes that chestnut has the functions of nourishing the kidney and spleen, strengthening the body, benefiting the stomach and calming the liver. [0003] Therefore, the processing method for chestnut kernel also emerges in an endless stream. In...
