Embodiment 1

[0025] Under the condition that the temperature of the environment is 25°C, take 1g of the fruit powder (average particle size is 90 mesh), add 60% by weight of ethanol aqueous solution (the ratio of solid to liquid is 1:25g / ml), and put it in the ultrasonic cleaner (The frequency of ultrasonic wave is 20KHz) for 30min, centrifuged at 4000rpm for 15min to get the supernatant.

Embodiment 2

[0027] According to the method of Example 1, the difference is that the ratio of solid to liquid is 1:20g / ml.

Embodiment 3

[0029] According to the method of Example 1, the difference is that the ratio of solid to liquid is 1:30g / ml.

Abstract

The invention discloses a method for extracting flavonoids from the fruit of Castanopsis chinensis. The method comprises: ultrasonically extracting the fruit powder of Castanopsis chinensis in ethanol solution, and then centrifuging to obtain the supernatant; The dosage (ratio of solid to liquid) is 1g: 20-40mL, the time of ultrasonic extraction is 20-40min, and the ethanol solution is 40-80% by weight. The method can efficiently and rapidly extract flavonoids from the fruit powder of Castanopsis chinensis.

Description

technical field [0001] The invention relates to the extraction of flavonoids, in particular to a method for extracting flavonoids from the fruit of Castanopsis chinensis. Background technique [0002] Castanopsis chinensis is abundant in southern Anhui and Dabie Mountains in our province. As a wild arbor tree species growing in mountainous areas, our province's mountainous resources are extremely rich and it is an important natural resource. Flavonoids are a strong antioxidant, which can effectively remove oxygen free radicals in the body; flavonoids can improve blood circulation, lower cholesterol, etc., and there are abundant flavonoids in the fruit. Existing extracts of the fruits of Castanopsis chinensis generally adopt the extraction method, but generally have the defects of low extraction efficiency and time-consuming. Contents of the invention [0003] The purpose of the present invention is to provide a method for extracting flavonoids from the fruit of Castanopsi...
