Problems solved by technology

[0005] In recent years, research groups have studied stilbenes in the seeds of medicinal plants peony: Literature [He Chunnian. Research on the Genetics of Paeonia Medicinal Plants, China Xiehe Medical University [D], 2010] reported the separation process of 9 stilbene compounds, the yield of the obtained stilbene compounds was very low, and the monomer stilbene compounds obtained from 4 kg of raw materials were at most more than 100 mg. Difficult to industrialize
In addition, the separation material used is peony seeds, and there are still problems in the application of toxic organic solvents in the research process.

Embodiment 1

[0090] A method for extracting a total stilbene compound composition of peony seeds, comprising the following steps:

[0091] 1) Take the raw material of Fengdan peony seeds, remove impurities, wash them twice with clean water, then place them in a constant temperature drying oven, dry them at 60°C for 3 hours, add them to a sheller to peel them after drying, and then peel the obtained peonies Dry the seed skins until the water content does not exceed 10%, crush them, take 100g and put them in an extractor, add ethanol with a mass concentration of 60% that is 10 times the weight of the peony seed skins, and reflux extraction at 40°C for 8 hours. Filtration, repeating the extraction and filtration process three times, combining the filtrate, evaporating and concentrating the filtrate obtained by filtration to obtain an extract, which is set aside;

[0092] 2) Dissolve the extract obtained in step 1) with 3 times its weight in acetone solvent, remove the insoluble matter, and th...

Embodiment 2

[0105] A method for extracting a total stilbene compound composition of peony seeds, comprising the following steps:

[0106] 1) Take the raw material of purple peony seeds, remove impurities, wash them with water for 3 times, then place them in a constant temperature drying oven, dry them at 80°C for 9 hours, add them to a sheller after drying, and peel the obtained peony seeds Dry the bark until the water content does not exceed 10%, crush it, take 300g and put it in an extractor, add ethanol with a mass concentration of 80% that is 20 times the weight of the peony seed bark, reflux and extract at 60°C for 10 hours, and filter after the extraction is completed , repeating the extraction and filtering process five times, merging the filtrate, and evaporating and concentrating the filtrate obtained by filtering to obtain an extract, which is set aside;

[0107] 2) Dissolve the extract obtained in step 1) with an ethanol solvent 5 times its weight, remove the insoluble matter, ...

Embodiment 3

[0120] A method for extracting a total stilbene compound composition of peony seeds, comprising the following steps:

[0121] 1) Take the mixed raw materials of peony seeds and peony seeds with a mass ratio of 1:1, remove impurities, wash with water for 3 times, then place them in a constant temperature drying oven, and dry them at 70°C for 6 hours. Add in the peeling machine to peel off, then dry the obtained peony seed skin to a water content of no more than 10%, pulverize, get 100g and place it in an extractor, add 70% ethanol with a mass concentration of 15 times the weight of the tree peony skin, Reflux extraction at 50°C for 9 hours, filter after the extraction, repeat the extraction and filtration process six times, combine the filtrate, evaporate and concentrate the filtered filtrate to obtain an extract, and set aside;

[0122] 2) Dissolve the extract obtained in step 1) with ethyl acetate solvent 4 times its weight, remove the insoluble matter, and then add an adsorb...

Abstract

The invention relates to a composition of peony seed total stilbene compounds as well as an extraction method and application thereof. The extraction method comprises the following steps: carrying out reflux extraction on peony seed skins by using ethanol, and filtering and concentrating to obtain an extract; then, dissolving the extract and mixing with an absorber; then, sequentially extracting the mixture by solvents; and finally, refining by using acetone and active carbon and concentrating till no solvents exist, thus obtaining the composition of the total stilbene compounds. The six compounds are respectively peony alcohol A, peony alcohol, peony alcohol C, cis-epsilon viniferin, trans-epsilon viniferin and common jointfir stem H. Verified by pharmacological experiments, the composition of the peony total stilbene compounds has good anti-gram positive and negative bacteria activity, can be used as an active component of anti-bacterial medicines and can be used independently or together with appropriate excipients to serve as a food additive for preservation of foods or can be used for preparing anti-bacterial medicines.

Description

technical field [0001] The present invention mainly relates to a total stilbene compound composition of peony seeds and its extraction method and application. Background technique [0002] Stilbeniods refer to the general term of monomers and their polymers with 1,2-stilbene skeleton. Oligostilbenes belong to phenolic acid compounds, which have a wide range of biological activities, such as antibacterial and antifungal activities, anti-inflammatory activities, antioxidant activities, anti-tumor activities, anti-AIDS activities and hepatoprotective activities.
