Abstract
The invention belongs to the technical field of traditional Chinese medicine pharmacy, relates to a radix Abelmoschi Manihot seed extract, and particularly relates to a radix Abelmoschi Manihot seed extract as well as a preparation method and medicinal application thereof. According to the invention, macroporous resin is used for extracting related active parts of the hollyhock seed water extract by using ethanol with different concentrations, and active parts with remarkable anti-inflammatory and analgesic effects, namely elution parts of 25% ethanol, are screened from different extraction parts through in vivo experiments of mice. According to the invention, the anti-inflammation and analgesic effect experiment is carried out on a mouse pathological model through extracts of different parts of a radix althaeae roseae to obtain an active part with an obvious anti-inflammation and analgesic effect; furthermore, the active part can be used for preparing anti-inflammatory and analgesic drugs.
Description
Technical Field
The invention belongs to the technical field of traditional Chinese medicine pharmacy, relates to a Uighur medicine extract, a preparation method thereof and application thereof in preparing anti-inflammatory and analgesic medicines, and particularly relates to an extraction method of a 25% ethanol extraction part of hollyhock seeds and application of the extract in preparing anti-inflammatory and analgesic medicines.
Background
Inflammation (inflammation), which is commonly referred to as "inflammation," is a defense response of the body to stimuli, manifested by redness, swelling, heat, pain, and dysfunction. The inflammation may or may not be infectious inflammation caused by infection. Inflammation is generally beneficial and an automatic defense response of the human body, but sometimes, inflammation is also harmful, such as attack on the body's own tissues, inflammation occurring in transparent tissues, and the like. The inflammation of the body is treated by anti-inflammation, and if hormone treatment is adopted, the problems of toxic and side effects or reduced hormone sensitivity can be caused, and the traditional medicine treatment is the current trend.
Hollyhock (academic name: Althaea rosea (Linn.) Cavan.) is a biennial upright plant of hollyhock of Malvaceae (Malvaceae), and is named as cloaca flower, jatropha, chessflower, chingma flower, juniper flower, lipsticks, fructus evodiae, and weizu, etc. The hollyhock has ornamental value and high medicinal value; the hollyhock is used as a medicine by using roots, stems, leaves, flowers and seeds. The hollyhock seed is a dry seed of the plant, is a traditional Uygur medicinal material, has multiple functions in Uygur medicine clinical and folk, has the functions of clearing heat, detoxifying, inducing diuresis, promoting urination, smoothing intestinal tracts, inducing diuresis, removing urinary calculus, promoting lactation and the like, is used for dysuria, eliminating facial freckles, and is used for treating diseases such as edema, stranguria, leukorrhagia, galactostasis, scabies, innominate toxic swelling and the like.
The inventor separates the active part with obvious anti-inflammatory and analgesic effects from the hollyhock seeds through experimental research, and can further research and develop a patent medicine or a compound preparation.
Disclosure of Invention
The invention aims to provide a Uighur medicine extract, a preparation method thereof and application thereof in preparing anti-inflammatory and analgesic medicines, and particularly relates to an extraction method of a 25% ethanol extraction part of hollyhock seeds and application of the extract in preparing anti-inflammatory and analgesic medicines.
The Viburnum orientale extract is a water extract of hollyhock seeds, and particularly is an elution part of hollyhock seeds with 25% ethanol.
The preparation method of the Uighur medicine extract is characterized by at least comprising the following steps:
(1) taking crude drugs; the crude drug is dry seeds of Althaea officinalis;
(2) extracting Althaea officinalis seed with distilled water, and extracting the residue with ethanol; filtering and mixing the two extracting solutions to obtain a hollyhock seed total extract; concentrating the total extract to obtain a sample solution;
(3) collecting the supernatant, passing through D-101 macroporous adsorbent resin, sequentially eluting with water and 25% ethanol to obtain 25% ethanol extract;
(4) filtering the 25% ethanol eluate of Althaea officinalis, concentrating, and drying under reduced pressure to obtain 25% ethanol eluate.
In the step (2) of the preparation method, the total extract is prepared by adding 12 times of water, decocting for 2 times, each time for 1.5 hours, and filtering. And finally, adding 95% ethanol in an amount which is 8 times that of the residue, decocting for 0.5 hour, filtering, combining the filtrates, concentrating, and drying under reduced pressure to prepare the total extract.
In step (2) of the preparation method of the present invention, the crude drug concentration of the sample solution is 0.8 Ag/ml.
In the step (3) of the preparation method, the adsorption flow rate of the macroporous resin is 2 column volumes per hour.
In the step (3) of the preparation method of the present invention, the dosages of water and 25% ethanol for elution by the macroporous resin are each 4 column volumes, respectively.
In the step (4) of the preparation method, distilled water is firstly used, and then 25% ethanol is used for elution.
In the step (4) of the preparation method of the invention, the flow rate of elution of the macroporous resin is 2 column volumes per hour.
According to the invention, the edema resisting and pain relieving effects of different parts of hollyhock seeds are observed through a mouse ear xylene-coated edema model and a mouse abdominal cavity acetic acid-injected pain model, and experimental results show that the effect of the 25% ethanol elution part is obviously higher than that of other parts; and then injecting acetic acid into the abdominal cavity of the mouse to cause a capillary permeability model to observe the protection of the capillary permeability of the 25% ethanol part, sensitizing the egg protein of the mouse to establish an asthma model to observe the protection of the lung cells and organs of the mouse, wherein the 25% ethanol part has obvious protection.
The results of the anti-inflammatory test are shown in Table 1
