Abstract
The invention relates to a method for separating and preparing high-purity specnuezhenide, nuezhenoside and oleanolic acid from natural plant glossy privet fruit by applying a high-speed countercurrent chromatography, which has the characteristics of no existence of irreversible adsorption and prevention of sample loss and has the advantages of good separating effect, less solvent dosage, no pollution, high efficiency, high speed and great preparation amount separation. The method is suitable for preparing a high-purity monomer by using various natural products containing one or more specnuezhenide, nuezhenoside and oleanolic acid obtained by various approaches and extracts of the natural products as raw materials and is simple and convenient as well as easy to apply.
Description
Technical field:
The invention belongs to the extracted form natural plant preparation field, relate to a kind of method of from the natural phant Glossy Privet Fruit, separating the special Ligustrum lucidum Ait of preparation, the bitter glycosides of glossy privet and Oleanolic Acid with high speed adverse current chromatogram.
Background technology:
Glossy Privet Fruit is Oleaceae (Oleaceae) plant glossy privet Ligustrum lucidum Ait dry mature fruit, is the traditional medicine of strengthening the body resistance to consolidate the constitution of China.Have yin-nourishing gas arranged, flat irascibility, strong waist knee, strengthen the bone, effect such as nourishing liver and kidney, black beard and hair.In recent years chronic tracheitis, hepatitis, hyperlipidemia, diabetes, involution syndrome, Infertility, atherosclerosiss etc. of being used for the treatment of more.Contained chemical ingredients mainly contains organic acid, glycosides, terpene, steroid class, carbohydrate, amino acid and trace element, volatile oil.Oleanolic Acid is its main pentacyclic triterpene composition, and the bitter glycosides of special Ligustrum lucidum Ait and glossy privet is its water-soluble secoiridoid glycosides composition.Structure is as follows:
The bitter glycosides Oleanolic Acid of special Ligustrum lucidum Ait glossy privet
Modern pharmacological research shows, Glossy Privet Fruit have cardiac stimulant, hormone two-ways regulation, reducing blood sugar and blood fat, adjusting body's immunity, anti-inflammatory, antibacterial, anti-ageing, atherosclerosis, can be to the effect of chemotherapy or caused by radiation oligoleukocythemia by leukocyte increasing.Special Ligustrum lucidum Ait has the collaborative ConA that increases suboptimal dose stimulates LT effect, and the restraining effect of antagonism Dex is arranged to a certain extent.Oleanolic Acid have the liver of protecting enzyme, platelet aggregation-against, reducing blood-fat fall, to immunity system and II, III, IV allergic reaction type are had obvious restraining effect.For Glossy Privet Fruit triterpene and secoiridoid glycosides composition are carried out researchs such as more deep pharmacologically active and mechanism of action, need index compositions such as triterpene and secoiridoid that glossy privet class medicinal material and relevant Chinese medicine preparation are carried out quality control simultaneously, need a large amount of monomeric compounds.Therefore, provide a kind of special Ligustrum lucidum Ait of separation and purification, the bitter glycosides of glossy privet and Oleanolic Acid method from glossy privet fast and efficiently, have the modern Chinese herbal medicine preparation of special efficacy and make full use of China's herb resource etc. significant exploitation.
Adopt the effective monomer in traditional separation method separating plant such as common chromatogram column technique, recrystallization, not only waste time and energy, contaminate environment, and used stationary phase has the non-reversibility adsorption to sample, and this just needs a kind of new separation technology to solve the problems referred to above.High speed adverse current chromatogram (HSCCC) be a kind of successive that development in recent years is got up need not the solid support thing efficiently, liquid liquid distribution chromatography isolation technique fast, have characteristics such as fractional dose is big, sample free of losses, rate of recovery height, isolating environment mitigation, saving solvent, be widely used in the preparation separation and the purifying of field chemical substances such as biology, medicine, environmental protection.
Summary of the invention:
The purpose of this invention is to provide the method that high speed adverse current chromatogram prepares special Ligustrum lucidum Ait, the bitter glycosides of glossy privet and Oleanolic Acid, to overcome the above-mentioned problems in the prior art.
The present invention is achieved through the following technical solutions:
High speed adverse current chromatogram prepares the method for special Ligustrum lucidum Ait, the bitter glycosides of glossy privet and Oleanolic Acid, and it may further comprise the steps:
Be made up of the preparation of crude extract and separation and purification two portions of crude extract, it is characterized in that high speed adverse current chromatogram is used in the separation and purification of crude extract, its basic technology route is:
(1) with the Glossy Privet Fruit pulverizing medicinal materials, the boiling water heating in water bath extracts, the extracting solution filtered while hot, and cooling obtains water and gets thing and residue;
(2) enrichment of special Ligustrum lucidum Ait, the bitter glycosides of glossy privet: aqueous extract is added absorption with macroporous adsorbent resin, and the 10-50% ethanol gradient elution is collected elutriant, and decompression recycling ethanol obtains special Ligustrum lucidum Ait, the bitter glycosides mixing of glossy privet crude extract;
(3) extraction of Oleanolic Acid: water is carried residue added in the ethanol that boils refluxing extraction 1-1.5 hour, extracts 1-3 time, filter extracting solution, add the gac reflux decolour again, filtration, concentrated destainer gets the Oleanolic Acid fluid extract;
(4) purifying of special Ligustrum lucidum Ait, the bitter glycosides of glossy privet: the pure product that crude extract made special Ligustrum lucidum Ait of high purity and the bitter glycosides of glossy privet with the high speed adverse current chromatogram partition method.
(5) purifying of Oleanolic Acid: above-mentioned Oleanolic Acid fluid extract is made the pure product of high purity oleanolic acid with the high speed adverse current chromatogram partition method.
