Problems solved by technology

During waste treatment, sisal waste residue and hemp juice are landfilled or dumped in the river near the factory, where they are decomposed and digested by microorganisms in the river water. As a result, untreated acidic sewage mixed with hemp residue and hemp juice affects the ecology of the river. The environment, and the lack of oxygen in the water affects the life of fish and microorganisms, further pollutes the ecological environment and causes waste of resources, which runs counter to the theme of "peace and development" in today's era, and greatly reduces the economical value of sisal. benefit

Abstract

The invention belongs to the technical field of plant active ingredient extraction, and discloses a method for extracting anti-oxidative active substances from waste sisal hemp residue. The method comprises the following steps of performing cleaning, impurity removal, drying, crushing and sieving on the sisal hemp residue subjected to fiber extraction; then, performing reflux extraction by an ethyl alcohol water solution with the volume fraction being 70 percent; performing filtration; performing vacuum concentration on filter liquid to obtain extracts; dispersing the extracts into water; adding petroleum ether; performing extraction to obtain petroleum ether extracts; then, sequentially extracting the extracted water solution by ethyl acetate and n-butyl alcohol; respectively obtaining ethyl acetate extracts and n-butyl alcohol extracts; drying the obtained petroleum ether extracts, the ethyl acetate extracts and the n-butyl alcohol extracts; and obtaining sisal hemp residue extract powder with different anti-oxidative activities. The extracting method provided by the invention has the advantages that the operation is simple; the extraction rate is high; the extraction range of the whole anti-oxidative substances in the sisal hemp residue is expanded; and the utilization rate of the sisal hemp residue is improved.

Description

technical field [0001] The invention belongs to the technical field of extracting plant active components, and in particular relates to a method for extracting antioxidant active substances from waste sisal residues. Background technique [0002] With the rapid development of the economy, sisal fiber is widely used in heavy industry due to its advantages of high strength, high durability, salt and alkali resistance and good stretchability. However, the content of sisal fiber only accounts for about 4% of the total amount of sisal, which also produces a large amount of sisal waste while bringing huge economic benefits. The sisal residue from which the sisal fiber has been extracted contains many economically useful substances such as sisal saponin which can be used as a medical material, pectin and chlorophyll which can be used as a food additive. However, sisal residue is usually used as organic fertilizer, animal feed or waste treatment in China. During waste treatment, s...
