Abstract

The invention discloses a method for extracting polyphenol from passion fruit peel. The method comprises the following steps: freeze-drying and crushing the passion fruit peel; carrying out ultrasonic wave-ethanol assisted extraction in a solution 30-80% ethanol under an ultrasonic power of 200-400 W at a temperature of 30-70 DEG C for 5-35 min, filtering the obtained solution by a 0.45-0.80 [mu]m nylon filter, and concentrating the filtered solution; and separating and purifying the obtained concentrate by macro-porous resin with the particle size of 0.30-1.25 mm, and carrying out vacuum freeze drying to obtain powder of polyphenol in the passion fruit peel. The extraction method ensures the extraction rate and the purity of the polyphenol through combining ultrasonic wave-ethanol assisted extraction, macro-porous resin separation and purification and vacuum freeze drying technologies. The extraction rate of the polyphenol in the passion fruit peel can reach 33.95-50.35%. The extraction method is a new method for effectively utilizing the passion fruit peel, and can change wastes into valuables.

Description

technical field [0001] The invention relates to the technical field of natural plant extraction, in particular to a method for extracting polyphenols in passion fruit peel. Background technique [0002] Plant polyphenols are complex phenolic secondary metabolites in plants, with a polyphenol structure, mainly found in the bark, roots, leaves, and fruits of plants, and their content in plants is second only to cellulose, hemicellulose, and woody white. Flavonoids in polyphenols are antioxidants. Medical research has found that polyphenols play an important role in the treatment of human diseases and health protection. They have various physiological functions such as anti-tumor, anti-oxidation, anti-arteriosclerosis, prevention and treatment of cardiovascular and cerebrovascular diseases such as coronary heart disease and stroke, and antibacterial. The "health guard" of nature and human beings. Since the late 1980s, basic research and applied research on plant polyphenols ...
