Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, and give preferred embodiments, the present invention will be further described in detail. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0025] A method for extracting custard apple lactone from Pineapple Sakyamuni, said method comprising the steps of:

[0026] Step 1: Pre-treat the extracted raw materials. The pretreatment includes washing and soaking, washing with warm water at 35 degrees Celsius, and soaking with hot water at a temperature of 45 degrees Celsius for 2 hours. The raw material is pineapple Sakyamuni seeds, which are cleaned in the early stage. Thereby reducing the introduction of impurities in the later stage.

Abstract

The invention discloses a method for extracting annonaceous acetogenin from atemoya, and belongs to the field of an annonaceous acetogenin extracting processes. The method comprises the following steps: pretreating an extracted raw material; drying the pretreated raw material, and then crushing by using a vacuum crusher to obtain crushed raw material powder; placing the crushed raw material powderinto a quick freezer for quick freezing to obtain ice powder, crushing the ice powder by using a crusher, unfreezing the crushed ice powder, and drying steam to obtain dry fine powder; placing the dried fine powder and water into a vacuum stirring tank for vacuum stirring; filtering to remove filter residues, and pouring filtrate into an extraction kettle for extraction; and collecting the extract after extracting for 2vh, extracting the extract with chloroform for 4 times, combining chloroform layers, carrying out vacuum filtration, recovering a solvent under reduced pressure at the temperature of 45 DEG C, and drying under reduced pressure to obtain the final product. The raw material is crushed for multiple times, and is crushed again after being frozen, so that the effect is good, theextraction efficiency of the raw material in the later period is high, a large amount of organic solvents are avoided, and the extraction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of extracting custard apple lactone, in particular to a method for extracting custard apple lactone from pineapple custard apple. Background technique [0002] The anti-tumor mechanism of anemone lactones is relatively unique. The latest research shows that the target of anemone lactones is the mitochondria of tumor cells. Its mechanism is to specifically inhibit the reductase or oxidase of mitochondrial NADH in tumor cells, thereby blocking the transfer of electrons, reducing the generation of ATP, and inhibiting the energy supply function of mitochondria. It not only has strong cytotoxic activity against different tumor cell lines, but also is effective against drug-resistant tumors including multidrug-resistant (MDR) tumors. Studies have shown that annona lactone compounds have significant anti-tumor activity, and some compounds have 40 to 300 times the activity of paclitaxel (Taxo1) in vivo. Afterwards...
