Abstract

The invention relates to the technical field of biomaterials, in particular to a preparation method of aromatic extracts from field muskmelon. The method comprises the steps as follows: firstly, fruitfield muskmelons are crushed, ground and then dissolved with absolute ethyl alcohol, an ultrasonic dispersion device is used for accelerating dissolution of effective substances, then, a dispersion liquid is subjected to reflux and reduced pressure evaporation with petroleum ether, a crude extract is obtained and subjected to full extraction with ethyl acetate, and an extract A and a residual extract B are obtained; a class-2 aromatic extract rich in ester aromatic substances can be obtained from the extract A through freeze drying, and a class-1 aromatic extract containing furans, aldehydesand sulfur-containing compounds can be obtained from the residual extract B through negative-pressure adsorptive filtration and rectification treatment. By the aid of the method, classified extractionof various aromatic substances in the field muskmelons can be realized, the extraction rate of effective substances is high, and the product purity is high after classified purification.

Description

technical field [0001] The invention relates to the technical field of biological materials, in particular to a method for preparing an aromatic extract of horse papaya. Background technique [0002] Horse cucumber is an annual herbaceous plant. Lingering, with a tendril on each node. The leaves are stalked, wedge-shaped or heart-shaped, and the leaf surface is rough and has bristles. Blooms in July and August, yellow flowers, monoecious, 3-5-lobed corolla, oblong ovary, long style sleeves, and 3 stigmas. Melons come in different sizes, the biggest ones are like goose eggs, and the smallest ones are like buttons. The melon tastes fragrant and sweet, sour and bitter, and the color of the melon skin is green, flowery, white or with green stripes. Seeds light yellow, flat, oblong, smooth surface, white kernel. [0003] Horse papaya grows in many places in my country and has strong growth characteristics. It is especially abundant in the dry land of Huaibei area. It is usua...
