Summary of the invention
The inventor has carried out deep exploration in this respect, and has obtained many gratifying results.
One object of the present invention is to provide the combination of Moschus and other active component, is used for the treatment of and/or prevents cardio-cerebrovascular diseases.
By a large amount of guiding tests, we tentatively determine to have such potential quality based on the medicine of Moschus+Radix Paeoniae.When attempt from prior art, to seek this bonded according to the time, we find: at Moschus can with the Radix Paeoniae use in conjunction, the mechanism of action of the two is underlying issues such as adduction, collaborative or antagonism, prior art does not up to now provide scientific basis.Whether can unite with other active component as for the two, prior art does not similarly hint again.
In traditional medicine, extremely extensive to the clinical practice of ranunculaceae plant Radix Paeoniae, for example in " typhoid fever is sunk " pandect 112 sides, count 33 head with the Radix Paeoniae person, account for 1/3rd (Li Zhongnan, Anhui Chinese Medicine College journal 1992,11 (2): 52-53) of total number formulary.The modern plants chemistry is thought, Radix Paeoniae Rubra, Radix Paeoniae Alba chemical constituent basically identical, Radix Paeoniae Alba total glycosides wherein is a main active, has pharmacologically active widely, cardiovascular disease, senile dementia, diabetes, inflammation, tumor, hepatopathy etc. there is certain curative effect (Fourier sea, Anhui medicine 2002,6 (2): 62-63; Ruan Jinlan, Acta Pharmacologica Sinica 2003,19 (9): 695-670).
That has carried out studies show that, the combination of Radix Paeoniae and Moschus can obviously strengthen the inherent pharmacological action of Moschus, such as anti-cerebral ischemia reperfusion injury and protect, anti-inflammatory response effect etc.
Therefore, one object of the present invention is to provide " Moschus+Radix Paeoniae " with synergistic function combination.
In pharmaceutical composition of the present invention, can select flavour of a drug (for example Radix Paeoniae, Moschus) directly to be ground into powder and be used as medicine, extract or other forms that also can be equivalent to above-mentioned natural drug material crude drug amount are used as medicine.Therefore, the active component of pharmaceutical composition of the present invention comprises the former powder of medical material, fat or water solubility extract (or effective site) or effective ingredient or monomer, perhaps adopts existing other goods forms in the prior art.For example, described active component comprises:
A. Moschus: be meant natural or the artificial Moschus, or contain the Moschus extract of glycoprotein, cholesterol etc. such as muscone, androsterone, Moschus-1, or the muscone monomer.
B. Radix Paeoniae: be meant the dry root powder of Radix Paeoniae (Radix Paeoniae Alba, Radix Paeoniae Rubra, river Radix Paeoniae Rubra), contain the extract of Radix Paeoniae Alba total glycosides compounds (being preferably peoniflorin and lactone glucoside of Radix Paeoniae), or the peoniflorin monomer.In addition, studies show that the effective site that contains peoniflorin, lactone glucoside of Radix Paeoniae, Hydroxy peoniflorin, oxypaeoniflorin, benzoylpaeoniflorin, lacdtlorin, paeonol, the former glycosides of paeonol, Cortex Moutan phenolic glycoside, Radix Paeoniae aglycon etc. simultaneously also is useful.The source that it will be appreciated by persons skilled in the art that Radix Paeoniae glycoside of the present invention is not limited to Radix Paeoniae, and the other plant (for example Cortex Moutan) that contains the Radix Paeoniae glycoside also can be realized the present invention, and it extracts and preparation method is a known technology, does not give unnecessary details at this.
Owing to compare with some existing plant amedica, Moschus lacks the active function of (or weak) blood vessel aspect, so based on above-mentioned achievement, we study " Moschus+Radix Paeoniae " and the probability of other active component combinations.
Therefore, except that above-mentioned two kinds of active component a, b, the present composition can also comprise Herba Erigerontis, can make the present composition have more comprehensive therapeutic effect by Herba Erigerontis.
In the test of carrying out subsequently, found very interesting phenomenon: " Moschus+Herba Erigerontis " or " Radix Paeoniae+oil lamp " do not have the present invention " Moschus+Radix Paeoniae+Herba Erigerontis " effect of Combination.This shows that the present invention's beneficial effect is not only to derive from Moschus, but derives from " Moschus+Radix Paeoniae " this basis combination.
Therefore, another object of the present invention is to provide " Moschus+Radix Paeoniae+Herba Erigerontis " with synergistic function combination.
Wherein, described Herba Erigerontis is meant: the scutellarin monomer of the lower alcohol extraction thing of the herb powder of Herba Erigerontis (having another name called Herba Erigerontis), the water extract of Herba Erigerontis, Herba Erigerontis (containing scutellarin (being scutellarin), single and or the effective site of dicaffeoylquinic acid etc.), breviscapine (containing scutellarin, breviscapine and other flavones ingredients) or free or sodium-salt form.It will be understood by those skilled in the art that, the source of scutellarin of the present invention is not limited to Herba Erigerontis, the other plant (for example Radix Scutellariae, Herba Scutellariae Barbatae etc.) that contains scutellarin also can be realized the present invention, equally, single and or the source of dicaffeoylquinic acid also be not limited to Herba Erigerontis, such as coffee bean, these extract and preparation method is a known technology, do not give unnecessary details at this.
Advantageously, on the basis of the above-mentioned useful combination of the present invention, other active component that can also add 15-200, preferred 30-120 weight portion in the present composition, for example extract of Radix Salviae Miltiorrhizae (active component salvianolic acid and/or TANSHINONES), Flos Carthami (active component Flos Carthami total flavochromes), Radix Puerariae (active component Radix Puerariae total flavones and/or puerarin), Semen Ginkgo (active component bilobalide and/or ginkgetin), Rhizoma Chuanxiong (active component ligustrazine and/or ferulic acid) or Radix Ginseng (active component Radix Ginseng total saponins).It is pointed out that adopting these plant extract active component or corresponding monomeric technology is known technology, does not give unnecessary details at this.
In context, the related term " active component " of pharmaceutical composition of the present invention has above-mentioned definition.
In pharmaceutical composition of the present invention, each components contents is:
Component a, 5-65, preferred 10-50, more preferably 15-45 weight portion; With
