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 an ultrasonic and microwave dual-assisted extraction method of total flavonoids of passion flower seed cake. The method herein comprises the steps of drying passion flower seeds at 55-70 DEG C to constant weight, crushing, screening to obtain seed powder, adding petroleum ether, with mass-volume ratio of the seed powder to the petroleum ether controlled to 6:(42-58), carrying out reflux condensation at 85-95 DEG C for 70-85 min, degreasing, recycling the petroleum ether via evaporation concentration, collecting degreased seed cake, adding ethanol-water solution, ultrasonically extracting under the thermostatic water bath condition of 75-85 DEG C to obtain a mixed liquid, carrying out microwave extraction, and filtering to obtain total flavonoid extract. The vibrational action and cavitation effect of the ultrasonic extraction technique are integrally utilized; the wall-breaking and heating effects of the microwave extraction technique enable the extraction efficiency to be greatly improved; the extraction technique is simple, and the extracting solvent is pollution free; utilization value of passion flower can be maximized.

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 ...
