Abstract
The invention provides a preparation method of total phenolic acid in a plant pithecellobium clypearia. The preparation method comprises the steps of crushing a pithecellobium clypearia raw material, extracting with pure water, condensing to form concrete, suspending with water, then putting on macroporous resin, eluting with acid water, removing water-soluble impurities, allowing phenolic acid substances to be maintained on the macroporous resin, eluting with a water-alcohol system to form a total phenolic acid extract which is also an effective part with pharmacological activity in the pithecellobium clypearia. The total phenolic acid in the pithecellobium clypearia has obvious antineoplastic activity, the pithecellobium clypearia, as traditional Chinese medicine, has lower toxic and side effects, and a new anti-tumor drug can be developed. The total phenolic acid in the pithecellobium clypearia can be prepared into various oral preparations. The method is reasonable in design and has the characteristics of simple technical process, low cost, low energy consumption and low pollution in a production process.
Description
Technical field
The present invention relates to plant medicine technical field, relate in particular to the preparation method of total phenolic acid (extract) in plant Ramulus Et Folium Pithecellobii Lucidi and the new application in preparing antitumor drug.
Background technology
Malignant tumor is the principal disease of harm humans health and lives.The whole world approximately has 5,000,000 people to die from malignant tumor every year according to estimates, is the second largest lethal cause of disease after cardiovascular disease.According to foreign data introduction, hundreds of kind PTS has been developed in the whole world, wherein much belongs to natural plant extracts.Nearly 130~150 kinds of the cancer therapy drug of current global various countries approved listing.Nearly 1300~1500 kinds of the various anti-cancer drug preparations that are mixed with these medicines.In addition the whole world studying among but not yet get the Green Light listing PTS approximately have kind more than 800, wherein belong in the treatment of approximately 400 kinds of cancers of micromolecular chemical anticarcinogenic drug, Drug therapy is a very important link, the effectively use of cancer therapy drug, can help patient to obtain longer life span, have the hope surviving, the most common cancer therapy drug has chemotherapeutics, Chinese medicine, bio-pharmaceuticals, targeted drug etc. at present.In numerous antineoplastic agents, the proportion maximum that natural plant kind antineoplastic agent is shared, has occupied 27.0% share, is secondly anti-metabolism tumor medicine, accounts for 26.1%.In the antineoplastic agent of first 10 of single product rank, plant antineoplastic agent has occupied two seats, is paclitaxel and docetaxel, has occupied respectively front two.Therefore, from plant, develop the antitumor drug making new advances, also become medicine scholars' research emphasis.
Ramulus Et Folium Pithecellobii Lucidi Pithecellobium clypearia (Jack) Benth. is Mimosaceae Ramulus Et Folium Pithecellobii Lucidi platymiscium, has another name called bib tree, flood dragon wood etc., is distributed widely in south China each province, has the effect of anti-inflammation, blood circulation promoting and dispersing pathogen accumulation.The single preparation of being made by the water extracted immersing paste of Ramulus Et Folium Pithecellobii Lucidi leaf and twig---Ramulus Et Folium Pithecellobii Lucidi antiimflammatory tablet (capsule) is used widely as antiinflammatory and treatment respiratory tract infection medicine, in 2005, be incorporated into Chinese Pharmacopoeia, there is clinically heat-clearing and toxic substances removing, removing heat from blood detumescence, the effect of antidiarrheal.For upper respiratory tract infection, acute pharyngolaryngitis, acute tonsillitis, acute gastroenteritis.Research before thinks, the active component of Ramulus Et Folium Pithecellobii Lucidi is mainly flavone and Flavane compound wherein.The patent of Ramulus Et Folium Pithecellobii Lucidi (publication number CN1850146A) has reported that Ramulus Et Folium Pithecellobii Lucidi extract has antiviral activity.Meanwhile, overwhelming majority research all concentrates on antiinflammatory, the anti-virus aspect of Ramulus Et Folium Pithecellobii Lucidi, also there is no the report of anti-tumor activity.
Summary of the invention
One of object of the present invention is to provide the preparation method of total phenolic acid of a kind of plant Ramulus Et Folium Pithecellobii Lucidi, the method is to be broken into coarse powder by getting Ramulus Et Folium Pithecellobii Lucidi raw material powder, with Aqua pure extract, normal pressure is concentrated into 25 ℃ and surveys the extractum that relative density is 1.25-1.30, and extractum is directly gone up macroporous resin and obtained total phenolic acid with water alcohol system eluting.The method adopts macroporous resin chromatography one step can obtain effective site, specifically by following steps, realizes:
1. get the Aqua pure extract 2~3 times that Ramulus Et Folium Pithecellobii Lucidi raw material doubly measures with 8-10, extract and adopt heating extraction or supersound extraction;
2. after extracting solution being merged, normal heating is concentrated into 25 ℃ and surveys the extractum that relative density is 1.25-1.30.
3. for gained extractum, after the water suspendible of 3 times of volumes, go up macroporous resin, after first using 3-5 column volume of sour water (PH:3-4) eluting, use again 40%-60% ethanol elution, collect ethanol elution, decompression recycling ethanol, spraying is dry obtains dried powder, and total yield is approximately more than 8%.The macroporous resin adopting is DM301, NKA-9, AB-8, D101, DM130, DM-18, D312 type low pole or Semi-polarity macroporous resin.
The dried powder of preparation is adopted to visible spectrophotometry, is reference substance with gallic acid (self-control, purity 97%), 0.6%FeCl
3-0.9%K
3[Fe (CN)
6] (1:0.9) mixed solution be developer, detect wavelength 720nm.Measure its total phenolic content.
Two of object of the present invention is to provide the new purposes of total phenolic acid in preparing antitumor drug in Ramulus Et Folium Pithecellobii Lucidi.The excipient preparation that in described plant Ramulus Et Folium Pithecellobii Lucidi, total phenolic acid adds pharmaceutics to allow is prepared into pharmaceutical preparation, and dosage form is various oral formulations.Described oral formulations comprises tablet, capsule, pill or granule.
The present invention has taked the process route different from former studies, directly uses water extraction, concentrated rear macroporous resin eluting.The tracking that the fraction that macroporous resin is eluted has carried out under anti-tumor activity guidance is separated, has screened and the new effective site with anti-tumor activity, and this effective site mainly contains phenolic acid and glucosides thereof, and the compound structure that wherein content is higher is as follows:
Ramulus Et Folium Pithecellobii Lucidi total phenolic acid extract has good in vitro and in vivo anti-tumor activity, and its toxic and side effects of chemical anti-tumor drugs is less relatively.The present invention is simultaneously also that Chinese medicine has been carried out to useful secondary development, for the development and utilization of Ramulus Et Folium Pithecellobii Lucidi provides more broad market prospect.
Usefulness of the present invention is: (1) has adopted in the past different extraction processes, the new total phenolic acid of effective site that utilized macroporous resin enrichment, and utilize the total phenolic content of spectrophotometry, its content reaches more than 80%, and be convenient to make various preparations, yield reaches more than 8%.(2) effective site obtaining by this method, has significant pharmacological action, can suppress the propagation of OPM, SGC-7901, SMMC-7721, RPMI-8226 and S180 tumor cell.(3) the total phenolic acid obtaining can be made various oral formulations, and administration is simple, and drug utilization degree is high.(4) the inventive method is reasonable in design, has that technique is simple, cost is low, energy consumption is low and production process is polluted low feature.
