Embodiment 1

[0030] Example 1 Preparation of Artemisia annua Extract

[0031] Artemisia annua waste residue extract was from an artemisinin manufacturer in Guangdong Province, and other reagents were commercially available products. Add 1000g of Artemisia annua extract to 1000g of silica gel, stir evenly, grind into powder, pass through a 60-mesh sieve, and separate quickly to obtain Artemisia annua waste residue extract powder; use 1800mL petroleum ether (PE) to extract Artemisia annua waste residue extract powder for 24 hours , filtered or centrifuged to obtain 732mL of the filtrate of the PE part, and 157.65g of the PE part extract was obtained after rotary concentration, and the obtained Artemisia annua extract was stored at low temperature (1-7°C) for future use.

Embodiment 2

[0032] Example 2 Preparation of Artemisia annua Extract

[0033] Artemisia annua waste residue extract was from an artemisinin manufacturer in Guangdong Province, and other reagents were commercially available products. Add 1000g of Artemisia annua extract to 1000g of silica gel, stir evenly, grind into powder, and pass through a 60-mesh sieve. Extract powder of Artemisia annua waste residue by rapid separation; extract powder of Artemisia annua waste residue extract with 1800mL of ethyl acetate (EA) for 24 hours, filter or centrifuge to obtain 1468mL of filtrate of EA part, and obtain 143.58 mL of EA part extract after rotary concentration g, stored at low temperature for later use.

Embodiment 3

[0034] Example 3 Preparation of Artemisia annua Extract

[0035] Artemisia annua waste residue extract was from an artemisinin manufacturer in Guangdong Province, and other reagents were commercially available products. Add 1000g of Artemisia annua extract to 1000g of silica gel, stir evenly, grind into powder, and pass through a 60-mesh sieve. Rapidly separated to obtain the extract powder of Artemisia annua waste residue; use 1800mL of PE: EA = 1: 1 (volume ratio) mixed solution to extract the extract powder of Artemisia annua waste residue for 24 hours, filter or centrifuge to obtain 1392mL of the filtrate of the mixed solution part, through After rotary concentration, 223.4 g of the partial extract of the mixed solution was obtained, which was stored at low temperature for future use.

Abstract

The invention discloses Artemisia apiacea extract and a preparation method and application thereof. The Artemisia apiacea extract is prepared by waste Artemisia apiacea residue discarded during the production of Artemisinin or directly by Artemisia apiacea plant, and has inhibiting effect on pathogenic bacteria of microbe diseases of picked fruits and vegetables and especially has obvious bacteria inhibition in vitro of picked fruit germs such as orange green mould, banana and mango anthracnose, Peronophythora litchi, grape gray mould and the like. Moreover, under living body conditions, the Artemisia apiacea extract can prevent and control diseases of the picked fruits such as oranges, litchi, bananas, grapes and the like, has good effect on the harmless preservation of fruits and vegetables, and can be used as botanical bacteriostat or fruit and vegetable preservative.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable preservation technology and pesticide technology, and specifically relates to the preparation and application of a plant extract, in particular to a kind of Artemisia annua extract, its preparation method and its use as a fungicide and preservative in fruit and vegetable preservation and postharvest application in disease control. Background technique [0002] The loss caused by rot caused by microbial diseases in the post-harvest storage of fruits and vegetables is very huge. According to data reports, the losses caused by rot in developed countries after harvest are about 15-24%. Lack of refrigeration equipment and poor hygienic conditions, the losses caused by post-harvest diseases of fruits and vegetables can be as high as 20-50%. [0003] At present, the chemical preservatives used at home and abroad to preserve the freshness of harvested fruits and vegetables mainly include Shibaogong, pr...
