Embodiment 1

[0017] Take 10,000g of fresh Luo Han Guo, wash it with warm water, immerse it in hot water at 60°C, extract the yellow pigment in the peel, filter the leachate, concentrate, spray dry, and recover the edible yellow pigment, put the leached yellow pigment in the Luo Han Guo In the incubator, put a small hole in one of the raw Luo Han Guo, put it into the contact of the temperature sensor, put it in the center of 10,000g Luo Han Guo, and heat it for 5 minutes after the temperature of the center of the fruit reaches 105°C, so that the protein in the Luo Han Guo cells solidifies into colloid, cannot be dissolved, then crush the heated Luo Han Guo fruit, extract with hot water at 70°C, and soak four times, each time for 2 hours, the resulting extract does not contain protein, then add 250g of pectinase at 55-60°C React for 2 hours to remove pectin under the conditions, then filter, concentrate and dry to obtain 300-350 g of crude product containing 43% tetracyclic triterpene, and th...

Embodiment 2

[0019] The heating device uses an autoclave, and others are the same as in Example 1.

Embodiment 3

[0021] Fresh Momordica grosvenori 1000g, heating device horse boiler, other with embodiment 1.

Abstract

A method for extracting fructus momordicae tetranuclear-triterpene is carried out by leaching flavine from fresh fructus momordicae skin by warm water, heating gelatinous protein in fruit cell, solidifying, crushing, leaching by 60-90 deg. C, de-bonding by pectase, filtering, concentrating and drying to obtain final product. Crude products containing tetranuclear-triterpene 43% 300-350g are extracted from fresh fruits 10000g. It's pure, safe, efficient, simple and cheap. It has no environmental pollution. The pumace can be made into feed.

Description

Technical field: [0001] The invention relates to a method for extracting effective components from fresh Luo Han Guo, in particular to a method for extracting tetracyclic triterpenes from Luo Han Guo. Background technique: [0002] The fruit of Luo Han Guo contains triterpene glycosides and other substances with high economic value and medicinal value. At present, there are many methods for extracting mogrosides from Luo Han Guo: the extraction method disclosed in Chinese patent 87101850 is to crush fresh Luo Han Guo, beat, warm water Extraction, and then use synthetic resin DA201 acrylic type adsorption separation, 50% ethanol to dissolve, D-211 acrylic type anion resin to decolorize, desalt, remove impurities, recover ethanol by distillation, concentrate under reduced pressure with a vacuum pump, and freeze-dry; Chinese patent 200510071877.0 The disclosed extraction method is: fresh Luo Han Guo pulverization→ethanol heating and reflux extraction→macroporous resin separatio...
