Embodiment 1

[0051] Embodiment 1 A kind of Baiwei extract

[0052] The Baiwei extract is prepared by the following steps:

[0053] 1. Baiwei is dried at 40 ℃, and after pulverizing, cross a 40-mesh sieve, and get the powder under the sieve;

[0054] II. in the powder that step 1 obtains, adding the weight percent concentration of 10 times of described Baiwei weight is 95% ethanol to carry out ultrasonic-assisted extraction, extraction temperature is 40 ℃, extraction time is 2 hours, and ultrasonic frequency is 30KHz; Filter, obtain alcohol extract;

[0055] III. In the alcohol extract obtained in step II, ethanol is recovered under reduced pressure until there is no alcohol smell, and the target product is obtained.

Embodiment 2

[0056] Embodiment 2 A kind of Baiwei extract

[0057] The Baiwei extract is prepared by the following steps:

[0058] 1. Dry Baiwei at 50 °C, cross a 40-mesh sieve after pulverizing, and get the powder under the sieve;

[0059] II. in the powder that step 1 obtains, adding the weight percent concentration of 20 times of described Baiwei weight is 40% ethanol to carry out ultrasonic-assisted extraction, extraction temperature is 50 ℃, extraction time is 2 hours, and ultrasonic frequency is 30KHz; Filter, obtain alcohol extract;

[0060] III. The alcohol extract obtained in step II, recover ethanol under reduced pressure until there is no alcohol smell to obtain the target product.

Embodiment 3

[0061] Embodiment 3 A kind of Baiwei extract

[0062] The Baiwei extract is prepared by the following method:

[0063] 1. Dry Baiwei at 50 °C, cross a 40-mesh sieve after pulverizing, and get the powder under the sieve;

[0064] II. in the powder that step 1 obtains, adding the weight percent concentration of 20 times of described Baiwei weight is 40% ethanol to carry out ultrasonic-assisted extraction, extraction temperature is 50 ℃, extraction time is 2 hours, and ultrasonic frequency is 30KHz; Filter, obtain Ethanol extract;

[0065] III. the ethanol extract that step II obtains, ethanol is reclaimed under reduced pressure to have no alcohol smell, and the ethanol extract of Baiwei is obtained;

[0066] IV. the described Baiwei ethanol extract that step III obtains is dissolved in the distilled water of 10 times of amounts (weight), after with the ethyl acetate extraction of the equal volume of distilled water three times, then use the n-butanol of equal volume to extract...

Abstract

The invention provides a preparation method of a cynanchum atratum extract. The preparation method of the cynanchum atratum extract comprises the step of extracting cynanchum atratum with ethanol under the assistance of ultrasonic waves and further comprises the step of extracting cynanchum atratum with n-butanol to obtain an n-butanol extract. The invention further provides the cynanchum atratum extract obtained by adopting the preparation method and application of the cynanchum atratum extract to preparation of a medicinal composition for inhibiting the harvested citrus from pathogenic bacteria. The cynanchum atratum extract has a strong effect of inhibiting the harvested citrus from pathogenic bacteria, can be used for preserving citrus without being left on the citrus, is harmless to the health of the human body and can not cause pollution to environment, and the pathogenic bacteria can not become resistant to the cynanchum atratum extract.

Description

technical field [0001] The invention belongs to the field of fruit disease prevention and preservation, and in particular relates to a Bai Wei extract capable of inhibiting post-harvest pathogenic bacteria of citrus, a preparation method and a new application thereof. Background technique [0002] Citrus is the world's number one traded fruit and the third most traded agricultural product. my country is rich in citrus resources and has a long history of planting. At present, the planting area and output of citrus in my country ranks first in the world. In 2013, the planting area of ​​citrus reached more than 36 million mu, and the total output was about 32 million tons. The citrus industry occupies a very important position in my country's agricultural economy. [0003] The citrus fruit tissue is tender and juicy and rich in sugar, which is prone to mechanical damage during the process of picking, storage, transportation, and sales. After the peel is damaged, it is suscepti...
