preparation example Construction

[0042] In view of the fact that the extraction rate of the current Xuan Papaya extraction method needs to be improved, the present invention provides a Xuan Papaya extract and its preparation method and application.

[0043] In a kind of preferred embodiment, the operating steps of preparing Xuan papaya extract are as follows:

[0044] (1) Take the dried Xuan papaya fruit, grind it into powder, take Xuan papaya powder (40-120 mesh) (2g) and mix with distilled water 10mL, put it in a reagent bottle with a lid after mixing, put it in a pressure cooker, and carry out Xuan papaya mixture obtained by high-pressure treatment, the high-pressure treatment conditions are: temperature 90-120 ° C, pressure 0.04-0.1 MPa, time 20-80 min;

[0045] (2) The high-pressure treated Xuan papaya powder mixture is subjected to reflux extraction treatment. The reflux solvent is ethanol and water, and the ratio of the two is 0%-100% water. The extraction time is 20-60 min. The ratio of solid to liqui...

Embodiment 1

[0060] (1) Take the dried Xuan papaya fruit, grind it into powder (40-120 mesh), take 10 mL of distilled water and 2 g of Xuan papaya powder, mix them, put them in a reagent bottle with a lid, put them in a pressure cooker, and perform high-pressure treatment The obtained mixture was sterilized under the following conditions: temperature 120°C, pressure 0.1MPa, time 40 min;

[0061] (2) The high-pressure treated Xuan papaya mixture is subjected to reflux extraction treatment, the reflux solvent is ethanol and water, the volume ratio of the two is 70:30, the extraction time is 120 min, and the ratio of solid to liquid is 1:40 by mass volume ratio , keep the extract slightly boiling at 80°C during the reflux process;

[0062] (3) After the extraction time is over, the extract is squeezed with a filter cloth to remove impurities, and centrifuged in a centrifuge at a speed of 4000 r / min for 5 min to obtain the papaya extract.

[0063] The papaya extract was characterized by the f...

Embodiment 2

[0075] (1) Take the dried Xuan papaya fruit, grind it into powder, take 10 mL of distilled water and 2 g of Xuan papaya powder, mix them, put them in a reagent bottle with a cover, put them in a pressure cooker, and perform high-pressure treatment to obtain the mixture. High-pressure treatment conditions It is: temperature 120°C, pressure 0.1MPa, time 60 min;

[0076] (2) The high-pressure treated Xuan papaya mixture is subjected to reflux extraction treatment, the reflux solvent is ethanol and water, the volume ratio of the two is 50:50, the extraction time is 40 min, and the ratio of solid to liquid is 1:40 by mass volume ratio , keep the extract slightly boiling at 80°C during the reflux process;

[0077] (3) After the extraction time is over, the extract is squeezed with a filter cloth to remove impurities, and centrifuged in a centrifuge at a speed of 4000 r / min for 5 min to obtain the papaya extract.

[0078] The same method as in Example 1 is used to calculate the extr...

Abstract

The invention relates to a chaenomeles speciosa extract as well as a preparation method and application thereof. The chaenomeles speciosa extract comprises the following components: 10-30wt% of polysaccharide, 7-40wt% of triterpene, and 1-4wt% of antioxidative active substances. The preparation method comprises the following steps: treating a proper amount of chaenomeles speciosa by a pressure cooker; mixing the chaenomeles speciosa powder after high-pressure treatment with different proportions of ethanol aqueous solution according to a certain proportion; carrying out reflux extraction; anddrying the extract to obtain the chaenomeles speciosa extract. According to the preparation method provided by the invention, the high-pressure treatment is utilized to destroy the tissue structure ofthe chaenomeles speciosa, so that the extraction rate of active ingredients in the chaenomeles speciosa and the contents of polysaccharide, triterpene and antioxidative active substances in the chaenomeles speciosa extract are improved.

Description

technical field [0001] The invention relates to the field of extraction of plant active substances, in particular, the invention relates to a papaya extract and its preparation method and application. Background technique [0002] Xuan papaya is a unique papaya variety in Xuancheng City, Anhui Province. It is a high-value food and medicine dual-purpose Chinese herbal medicine. "The name. Xuan papaya is mostly used for medicinal purposes because it is rich in organic acids and tannins, which make it taste sour. Xuan papaya extract is rich in active ingredients such as polysaccharides, organic acids and triterpenes. Existing Xuan papaya extraction methods mainly include extraction methods such as ultrasonic wave, reflux, and percolation. The existing extraction rates are not high, and the ratio of the weight of the extract to the weight of the material is basically no more than 75%. [0003] The pressure cooker is usually used for microbial sterilization treatment, the ster...
