Abstract

The invention relates to a method for extracting effective components in dropped fruit of tangerines and tangerine peels. The method comprises the following steps: degreasing the materials, performing backflow by ethanol with concentration being 75% and performing ultrasonic-assisted extraction to obtain an extract, concentrating the extract and layering the extract by chloroform, and respectively obtaining the high-purity hesperidin finished product, the synephrine finished product and the limonin finished product by using different methods. The method is adapted to industrial production, can increase the comprehensive utilization rate of dropped fruit of tangerines and tangerine peels, increases the economical utilization value, and promotes the further development of a tangerines industry.

Description

technical field [0001] The invention relates to the technical field of extracting active ingredients in plants, in particular to a method for extracting active ingredients in citrus fruit drop and orange peel. Background technique [0002] Citrus trees are easy to form flowers, but the fruit setting rate is low, generally 3-5%. During the growth process from young citrus fruits to mature citrus, due to insect pests, soil fertilizer and water shortage, improper application of pesticides, flower thinning and sparse Improper fruit control and changes in natural conditions can cause fruit drop. my country is a big citrus producing country. A large number of citrus fruit drop occurs in the process of citrus planting every year. As we all know, citrus drop also contains rich nutrients, such as essential oils, pigments , pectin, flavonoids, dietary fiber, etc., while the fruit growers in general plantations use composting and discarding of citrus fruit drop, which pollutes the enviro...
