Problems solved by technology

[0003] Studies have shown that the residue after extracting mogroside contains not less than 1.5% (based on the weight of the slag) of farnesol, not less than 74% of dietary fiber, and a small amount of fatty aldehyde. If it is discarded as it is at present , is undoubtedly a pity waste of resources

Embodiment 1

[0027] Take 100g dry weight of fresh fruit residue after extracting mogroside, separate the seeds and hulls to obtain 8.2g seeds. Squeeze the seed oil with an ordinary juicer to obtain 1.66 g of seed oil.

Embodiment 2

[0029] Reflux 32.6g of seed powder (from fresh fruit residue, dry weight) with ether for 2h, filter out the liquid, wash the residue with a small amount of ether, combine the washing liquid with the filtrate, suck it into a thin-film evaporator, and recover ether under normal pressure to obtain residual Liquid is seed oil 10g. The above filter residue was refluxed with ethyl acetate for 2h, and 3g of seed oil was collected according to the above steps. A total of 13g of seed oil was obtained in two steps, and the yield was 39.9% (by weight of seeds).

Embodiment 3

[0031] Take 50 g of the seeds separated from the dried fruit residue of Luo Han Guo, reflux with ethyl acetate for 2 hours, filter, and reflux the filter residue with ethyl acetate for 2 hours, filter, and wash the residue with a small amount of ethyl acetate, combine the filtrate and washing solution twice, and inhale In a thin film evaporator, ethyl acetate was recovered under reduced pressure to obtain a residual liquid, namely 20.7 g of seed oil, with a yield of 41.4% (by weight of the seeds).

Abstract

A process for extracting the active components (farnesol, fatty aldehyde and edible fibres) from the momordica grosvenori dregs generated after extracting glycoside includes extracting seed oil, extracting farnesol by fraction, extracting fatty aldehyde from the water phase, and preparing edible fibres from the dregs by chemical or enzyme method. Its advantages are simple process and high output rate.

Description

(1) Technical field: [0001] The invention relates to a method for extracting multiple active ingredients from Luo Han Guo residue. Specifically, it is a method for extracting farnesol, fatty aldehyde and dietary fiber from Luo Han Guo residue. (two) background technology: [0002] Farnesol, whose chemical name is 3,7,11-trimethyl-2,6,10-dodecatrien-1-ol, is a thickener for high-end perfumes and is expensive, about $14.5 / g. Farnesol was first isolated from roses, citronella, lemons, oranges, etc., but its development was restricted due to too little content. Farnesol was successfully synthesized in 1960, but its synthetic route was complicated and the cost was relatively high. High, so the market price is also very high (there is no domestic manufacturer). Some fatty aldehydes are components of perfume, and many fatty aldehydes are widely used in cosmetics, medicine and hygiene. Dietary fiber refers to some substances contained in plants that cannot be decomposed by huma...
