The single herbal medicine is used for the treatment of a kind of important means that disease is Chinese materia medica and folk medicine.The red sage root is simply to prevention and treatment cardiovascular disorder such as effective Chinese medicine such as stenocardia, coronary heart disease and apoplexy.The general using method of the red sage root is concluded and is mainly contained two big classes at present:
1. single salvia piece or after other Chinese medicines decoct into decoction of medicinal ingredients, take.
2. the finished medicines that becomes various formulations by factory process is as back uses such as oral preparation, injection and aerosols.
Red sage root finished medicines especially injection is widely used clinically.The Chemical Composition of the red sage root mainly is made up of fat-soluble composition and water-soluble components two portions.The chemical work of the previous red sage root concentrates on fat-soluble composition mostly, and therefrom isolating TANSHINONES is a series of diterpene compounds of representative, confirms that through pharmacological testing this compounds has certain physiologically active.Thereafter (pharmacy circular such as Chen Zheng hero.1981,16 (9), 2425) at first carried out the research of the water-soluble components of the red sage root, found rancinamycin IV, Salvianic acidA, salvianolic acid first and the second grade water-soluble cpds, pharmacologically active shows that they have the effect of certain enhancing mouse hypoxia-bearing capability.In view of salvianolic acid is difficult to obtain pure product, and the more easily separated and synthetic acquisition of rancinamycin IV and Salvianic acidA, so existing red sage root patent medicine preparation such as the water miscible Salvianic acidA of quality control major control of Radix Salviae Miltiorrhizae Injection and the content of rancinamycin IV, oral preparations then detects water miscible Salvianic acidA and fat-soluble TANSHINONES simultaneously.A large amount of pharmacology and clinical study result show that the activity of the water-soluble components of the red sage root is better than fat-soluble composition, and rancinamycin IV toxic side effect, Salvianic acidA represent the activity of the red sage root very unreasonable.Ma Li Lian waited and systematically the salvianolic acid compounds to be carried out extensive work the end of the eighties, isolated compounds such as salvianolic acid A, B and C, but failed fundamentally to illustrate the main active ingredient of the red sage root equally.((a) Planta Medica 1984,50 (3), 227; 1992,58 (2), 197; (b) J.Nat.Prod.1988,51 (1), 145; (C) Phytochemistry.1992,31 (2), 1068; When (d) ChineseChem.Lett.1993,4 (6), 501) Japanese scholar Xi Gang five husbands wait the full effective ingredient of research Treated with Radix Salviae Miltiorrhizae kidney, isolate salvianolic acid B magnesium, but do not illustrate it yet the active contribution of the red sage root (Chem, Pharm.Bull.1989,37 (2), 340).Because the effective ingredient research of the red sage root lags behind, the quality of domestic red sage formulation and effect can not get ensureing that the different lot number product clinical effectiveness of the product of different manufacturers or same producer differ greatly, and lack reliable Quality Control foundation.
The objective of the invention is by Study on extraction red sage root aqueous solution composition, the mould rope goes out a kind of method simple and easy, the efficient production salvianolate also to be determined to make quality control index with the salvianolic acid B magnesium in the poly phenolic acid of Radix Salviae Miltiorrhizae salt mixture, improves its treatment cardiovascular and cerebrovascular diseases result of use.
The present invention mainly pulverizes the back with the red sage root and carries with hydro-thermal, extracting fully, back water is concentrated, concentrated solution centrifuging, filtered liquid are removed impurity through macroporous resin adsorption with water wash, be adsorbed in polyphenol hydrochlorate on the macroporous resin through with moisture lower alcohol wash-out, elutriant is evaporated to certain volume, adds dehydrated alcohol, alcohol precipitation, inclining supernatant liquor and discards throw out, and the supernatant liquor that inclines is evaporated to dried.Drying and crushing gets salvianolic acid salt.
The present invention implements through the following steps.
[separation of salvia-soluble composition]
Pulverize red rooted salvia, use hot water extraction then, the centrifuging of extracting solution concentrating under reduced pressure, solution is further through Sephadex LH-20, TSK gel Toyopearl HW 40 F, reversed phase chromatography carrier column chromatographies such as MCI gel CHP 20P.CosmosilODS obtain eight compounds respectively, and to measure each compound structure as follows through chemistry and spectral method:
Salvianolic acid salt is the mixture of salvia-soluble phenol sexual element, mainly contain salvianolic acid B magnesium (compound 6), salvianolic acid salt mixture and existing salvia-soluble composition product such as Radix Salviae Miltiorrhizae Injection, in the kind of effective ingredient, there is very big difference aspects such as content and activity.Through showing with the HPLC quantitative analysis, salvianolic acid B magnesium is the main ingredient in the salvia-soluble composition, and its content accounts for 60% of salvia-soluble phenol sexual element.
[biological activity determination]
The antioxygenation of red sage root component adopts (Biochemical Pharmacology 1992 such as Liu, 43 (2), 147) reported method is measured, and platelet aggregation-against and hypoxia endurance test adopt Liang Zijun (Li Yikui etc., herbal pharmacology experimental technique etc., Shanghai science tech publishing house, 1991 the 82nd page) and Qi Chen east (Li Yikui etc., herbal pharmacology experimental methodology, Shanghai science tech publishing house, 1991, the 110th page) reported method mensuration.Measurement result sees Table one to table six.
Eight compounds of salvia miltiorrhiza tanshinoate salt except that compound 7 must measure atomic, all the other seven compounds are anti-oxidant to it respectively, platelet aggregation-against and mouse hypoxia tolerance are tested, compound 6 all shows the strongest activity on four screening models as can be known from table one to table four, and Salvianic acidA is then active unsatisfactory.Utilize hydrogen type cation exchange resin to prepare the corresponding acidulants of compound 6 and salvianolate respectively, it is suitable with compound 6 during at high dosage as its activity of mixture from the visible salvia miltiorrhiza tanshinoate salt of table five and table six at the activity intensity on the mouse hypoxia tolerance model of platelet aggregation-against further to have compared salt and acid, then not as compound 6, their acidulants activity is the poorest during low dosage.Above-mentioned chemistry and pharmacology result show that the content of compound 6 can be used as the quality control index of salvianolate, can be in the application in the treatment cardiovascular medicament through biological activity test proof salvianolate.

[preparation of salvianolate]
The red sage root of chopping is boiled with boiling water and carries 2-4 time, first water consumption be about the crude drug amount 4-8 doubly, extracting solution is through concentrating after-filtration, (macroporous resin is to be the commercially available porousness adsorption chromatography carrier that bridging materials makes with vinylbenzene by macroporous resin adsorption, can use Amberlite XAD series and domestic resin roughly the same, for example raise the 1300-1 macroporous resin of continent pharmaceutical factory etc.) wash decon with water, use moisture C again
1-C
5The lower alcohol wash-out, the wash-out lower alcohol is methyl alcohol, ethanol or propyl alcohol etc., the concentration of moisture lower alcohol is 30-80%, the aqueous alcohol consumption is about 5-10 times of crude drug amount, collect the lower alcohol elutriant, concentrating under reduced pressure, the alcohol concn of final alcohol precipitation is 75-95%, the 0.5-2 that the alcohol precipitation liquor capacity is equivalent to the crude drug amount doubly, product yield more than 2.5% of dose of making a living.
