Abstract

The invention discloses an extraction method of moringa oleifera leaf extractive. The extraction method is characterized by comprising the following steps of 1 crushing, wherein moringa oleifera leaves are crushed into 40-100-mesh powder; 2 ultrasonic extracting, wherein the moringa oleifera leaf powder is extracted by adopting an ultrasonic extractor; 4 filtering, wherein frame filtering is performed on an extracting solution, and a material solution processed through frame filtering is filtered through microfiltration to obtain a microfiltration dialysis solution; 5 concentrating, wherein the microfiltration dialysis solution is concentrated through reverse osmosis circulation until the diopter of a reverse osmosis concentrated solution is larger than 10; 6 extracting, wherein the reverse osmosis concentrated solution is extracted by adopting petroleum ether, a water-layer clear solution is collected, and beta-cyclodextrin with 1-3 percent of solid content is added in the supernatant solution and stirred evenly; 7 spraying and drying, wherein spraying and drying are performed to obtain the faint yellow moringa oleifera leaf extractive. According to the extraction method of the moringa oleifera leaf extractive, the unique fragrance of the extractive is maintained while it is guaranteed that the water solubility of a finished product is achieved and the finished product is clear and bright, and meanwhile flavone and polysaccharide in the extractive cannot be lost.

Description

technical field [0001] The invention relates to the field of plant extraction, in particular to a method for extracting Moringa oleifera leaf extract. Background technique [0002] Moringa, Moringa oleifera, is a tropical plant with unique economic value. Moringa leaves are rich in various minerals, vitamins, health care and medicinal chemical components. They can be used as vegetables and food, have the functions of supplementing nutrition and dietotherapy, and can also be used to prevent and treat some diseases. Folk traditions believe that Moringa has the functions of reducing fever, reducing inflammation, removing stones, diuretic, lowering blood pressure, relieving pain, strengthening the heart, and aphrodisiac. India and African countries are often used to treat diabetes, high blood pressure, cardiovascular disease, obesity, skin diseases, eye diseases, low immunity, scurvy, anemia, arthritis, rheumatism, digestive system tumors and other diseases. In the prior art, ...
