Embodiment Construction

[0010] The present invention uses pulsed ultrasonic technology to extract polyphenols in lotus pods. The process steps of the present invention are: weigh 2.0 g of degreased lotus pod powder and place it in a narrow-mouth beaker, and the ratio of material to liquid is 1:10 to 1: 35 Add a certain amount of 70% acetone, put the narrow-mouth beaker in a water bath (with magnetic stirring), and then put the ultrasonic probe into the narrow-mouth beaker (1 cm below the liquid level) for ultrasonic-assisted extraction. The extraction temperature The temperature is 20-60°C, the ultrasonic time is 10-35min, and the ultrasonic power is 600-1100W.

[0011] The present invention selects extraction temperature, ultrasonic time, ultrasonic power, solid-liquid ratio as single factor, and their influence on the extraction rate of polyphenols is shown in figure 1 , figure 2 , image 3 .

[0012] As a preferred solution, the process parameters of the present invention are: ultraso...

Abstract

The invention belongs to the field of Chinese traditional medicine processing and in particular relates to an extraction process of lotus seedpod polyphenols. The invention provides the extraction process of lotus seedpod polyphenols which is short in consumed time and high in yield. The extraction process comprises the following processing steps of: weighing 2.0g of defatted lotus seedpod powder, placing the defatted lotus seedpod powder into a thin-mouth flask, adding a certain amount of 70% acetone according to a material-liquid ratio of 1:10-1:35, placing the thin-mouth flask into a water bath pot (with magnetic stirring), and then placing an ultrasonic probe into the thin-mouth flask (1cm below the liquid level) for ultrasonic assisted extraction, with the extraction temperature being 20-60 DEG C, the ultrasonic time being 10-35 min, and the ultrasonic power being 600-1100W.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine processing, and more specifically relates to a process for extracting lotus pod polyphenols. Background technique [0002] Lotus, also known as lotus and lotus, is a perennial aquatic perennial herb. Its underground stem is called lotus root, which can be used. The leaves are used as medicine. The whole body of the lotus is a treasure. The lotus root, leaves, petioles, lotus stamens, and lotus pod (receptacle) are used as medicine to clear away heat and stop bleeding; , Nourishing the heart and kidney. Lotus root can be eaten as a vegetable or extracted from starch (lotus root starch). [0003] The non-edible part of the lotus, the lotus pod (also known as the lotus shell), has been regarded as agricultural waste and discarded in large quantities, which affects the full utilization of lotus resources. Because plant polyphenols have strong free radical scavenging and antioxidant activ...
