Problems solved by technology

If the solid-liquid ratio is too large, the concentration difference of flavonoids between the raw material and the solvent is too small, and the mass transfer driving force is too low, which is not conducive to the dissolution of flavonoids, resulting in a low extraction content of flavonoids

Abstract

The invention discloses a method for extracting total flavonoids from passionflower seed oil and meal with the double assistance of ultrasonic waves and microwaves. The method comprises the following steps: drying passionflower seeds at 55-70°C to constant weight, crushing, and sieving to obtain seed powder, adding petroleum ether, and controlling the mass-volume ratio of seed powder to petroleum ether to 6:42 ~58, 85~95℃ reflux for 70~85min to degrease, evaporate and concentrate to recover petroleum ether, collect the degreased seed oil meal; add ethanol-water solution, and conduct ultrasonic extraction in a constant temperature water bath at 75~85℃ to obtain a mixed solution , carry out microwave extraction, and filter to obtain the total flavonoid extract. The invention integrates the vibration effect and cavitation effect of the ultrasonic extraction technology, and the wall-breaking and heating effects of the microwave extraction technology, so that the extraction efficiency is greatly increased. At the same time, the extraction process is simple and the extraction solvent is pollution-free. Passiflora can be utilized Maximize value.

Description

technical field [0001] The invention belongs to the technical field of plant natural component extraction. Specifically, it relates to a method for extracting total flavonoids from passion flower seed oil meal with ultrasonic and microwave assistance. Background technique [0002] Passiflora edulis Sims (Passiflora edulis Sims) is a vine of the genus Passiflora in the Passiflora family. It is planted on a large scale in Yunnan, Guangdong, Guangxi and other provinces in my country. Its fruit juice has a pleasant fragrance and unique flavor, and occupies an important position in the beverage market. status. Passion fruit produces seeds accounting for about 11% of the whole fruit after the juice is extracted, and the oil content of the seeds is about 20%. At present, the research on the utilization of passion fruit seeds at home and abroad mainly focuses on the development of seed oil. The research on the active ingredients of purple passion fruit seeds shows that it contains ...
