Embodiment 1

[0031] Embodiment one: the preparation of purified product

[0032] The purified white hemp with anti-inflammatory activity provided by the present invention is prepared by the following preparation method:

[0033] (1) Add ethanol solution to reflux extraction for 1-2h / time in the white hemp sample, and combine the extracts;

[0034] (2) Concentrating the extract of step (1) to alcohol-free;

[0035](3) After the concentrated extract, add deionized water to adjust the concentration to 0.02-0.1g / ml liquid medicine, pass through the macroporous resin column, 1-3BV water to elute and remove impurities at a speed of 1-2BV / h, and then add 1-4BV 60%-90% ethanol is eluted at a rate of 1-2BV / h and the eluate is collected, concentrated and dried to obtain a purified product.

[0036] The composition of the purified white hemp prepared by the preparation method of the present invention contains the following substances: more than 10% of leucin, and at least agaricin, isorhamnetin-3-O...

Embodiment 2

[0037] Embodiment two: the preparation of purified product

[0038] Add 15 times the weight of 70% ethanol to the big-leaf white hemp sample and reflux extract twice, 1.5h / time, concentrate the extract to no alcohol, add deionized water to adjust the concentration to 0.05g / ml liquid, and pass the non-polar Macroporous resin column, eluted with 2BV water at a rate of 1.5BV / h to remove impurities, then added 2.5Bv 75% ethanol solution for elution and collected the eluate, concentrated and dried the collected eluate to obtain the purified product.

Embodiment 3

[0039] Embodiment three: the preparation of purified product

[0040] Add 10 times the weight of 80% ethanol to the big-leaf white hemp sample to reflux and extract once, 1h / time, the extract is concentrated to no alcohol by vacuum distillation, and the concentration is adjusted to 0.02g / ml liquid by adding deionized water. After passing through a HPD300 macroporous resin column, 1BV of water was eluted at a rate of 1BV / h to remove impurities, and then 1BV of 60% ethanol was added to elute at a rate of 1BV / h. The eluate was collected, concentrated, and dried to obtain a purified product.

Abstract

The invention provides a poacynum hendersonii purified material with antiphlogistic activity. The material is prepared by a following preparation method with the steps of (1) adding 15 times of weightof 70-percent ethyl alcohol into a poacynum hendersonii sample for backflow extraction for two times according to 1.5h/time; merging extraction liquid; 2) concentrating the extraction liquid until noalcohol exists; (3) adding deionized water into the concentrated extraction liquid for dilution; passing the material through a macroporous resin column; performing fast water washing for impurity removal; then, adding 75-percent ethyl alcohol for elution; collecting the elution liquid; performing concentration and drying to obtain the purified materials. The poacynum hendersonii purified material enriches the ingredients with the antiphlogistic activity in the poacynum hendersonii, so that the antiphlogistic activity of the poacynum hendersonii purified material is improved, so that the poacynum hendersonii purified material can be applied to the preparation of relevant products for preventing and treating inflammatory diseases.

Description

technical field [0001] The invention relates to the technical field of medicine preparation, in particular, the invention relates to the technical field of preparation and application of white hemp. technical background [0002] Inflammation is the body's stress response to infection or injury and helps the body get back to normal as quickly as possible. Many infectious diseases and chronic non-communicable diseases such as cardiovascular diseases, malignant tumors, diabetes, and autoimmune diseases belong to the category of inflammatory diseases. These diseases have spread globally and have evolved into important public health problems that seriously endanger human health. , Screening anti-inflammatory active ingredients and components can provide a new direction for the prevention and treatment of related diseases. [0003] Big-leaf white hemp, Apocynaceae white hemp, another name: Apocynum white hemp, wild hemp, big-flowered apocynum, is an upright semi-shrub, mainly dis...
