Method for extracting functional ingredient of bee glue by ultrasonic wave process

Abstract

The present invention relates to a method for extracting functional components of propolis by utilizing ultrasonic wave technology, belonging to the field of propolis extract technology. Said invention uses ethyl alcohol as solvent, and adopts the following steps: freezing crude propolis, pulverizing and dissolving the crude propolis in ethyl alcohol, extracting by using ultrasonic technique, filtering, vacuum concentrating filtrate so as to obtain the finished product propolis. At the same time of vacuum concentration the ethyl alcohol can be synchronously recovered. It can raise extraction rate, shorten extraction time and can prepare high-quality propolis product.

Description

technical field [0001] The invention discloses a method for extracting propolis functional components by ultrasonic technology, which belongs to the technical field of propolis extracts. Background technique [0002] Propolis (propolis) is known as "purple gold". It is a gum that bees collect from plant spores and tree trunks, and mixed with bee mandibular gland secretions and beeswax. It contains 50-55% resins, aromatic oils, 30-40% beeswax, 5-10% pollen, and alkyl acid oils, fats, amino acids, organic acids, iron, copper, manganese, zinc, plant Bactericides, B vitamins, vitamins E, C, H, provitamin A, antibiotics, enzymes, etc. In terms of compounds, there are mainly flavonoid compounds, organic acid compounds, esters, aldehydes, alcohol compounds, and alkenes, hydrocarbons, and alkene compounds. Flavonoids are the main bioactive substances of propolis, and there are about 20 kinds, including flavonoids, flavonols and flavonoids. [0003] In recent years, reports on the...
