Abstract

The invention discloses a preparation method of a purslane extract and the obtained purslane extract. The method comprises the following steps: (1) taking a clean purslane raw material, and crushing the purslane raw material to 10-100 mesh; (2) adding 5-15 times of an extraction solvent into the purslane powder obtained in the step (1), and carrying out extraction at the temperature of 30-80 DEG C, wherein the adopted extraction solvent is ammonia water and / or a sodium carbonate solution; (3) cooling the mixture obtained in the step (2), and then carrying out filtering; and (4) carrying out vacuum concentration on the filtrate obtained in the step (3) to obtain a dry purslane extract. The novel extraction solvent disclosed by the invention is good in dissolving compatibility on portulaca oleracea polysaccharides, flavonoids and alkaloids, low in cost, safe and efficient.

Description

technical field [0001] The invention relates to a method for extracting purslane extract and a product thereof, more specifically, the invention relates to a method for extracting purslane extract without using an organic solvent and the product obtained. Background technique [0002] The composition of purslane is very complex, it contains a large amount of polysaccharides, bioflavonoids, alkaloids, various fatty acids (mainly unsaturated fatty acids such as W-3 fatty acids, SL3 fatty acids), norepinephrine, dihydroxyphenylethylamine, Potassium, VE, VC, β-carotene, glutathione and other substances that have nutritional health care and medical effects on the human body. [0003] At present, the extraction solvent used in the preparation method of purslane extract includes two categories. The first category is alcohol water as an extractant, which accelerates the dissolution of active ingredients by heating, and there are also reports of extraction based on heating and ultras...
