Description
Technical field
The present invention relates to a kind of Chinese medicine preparation and preparation method thereof, particularly relate to preparation of effective site in a kind of red rooted salvia and preparation method thereof.
Background technology
Radix Salviae Miltiorrhizae is the root of Labiatae salvia Radix Salviae Miltiorrhizae Salvia miltiorrhiza Bge..Bitter in the mouth, cold nature has blood circulation promoting and blood stasis dispelling, nourishing blood to tranquillize the mind, the effect of removing heat from blood row's carbuncle and toxin expelling granulation promoting is the flavour of a drug commonly used of Chinese medicine blood circulation promoting and blood stasis dispelling.The limitation of existing red sage formulation technology shows as: though 1, alcohol extraction process extracts more complete to tanshinone, but because the unstability of tanshinone, concentrate, in the dry run loss more, cause the low and content poor reproducibility of tanshinone retention rate in preparation; 2, tanshinone is poorly soluble, and dissolution is low in the preparation.Existing preparation does not screen suitable adjuvant and technology, to improve the tanshinone dissolution; 3, the extraction of water solublity salvianolic acid class is index with the danshensu, and loss of active ingredients such as danshensu is bigger in the precipitate with ethanol process for refining, and retention rate is low in preparation; 4, absorb in the danshensu body, metabolism is fast, ordinary preparation is difficult to keep the stability of oral administration blood drug level.
The red rooted salvia master contains fat-soluble Diterpenes composition and water miscible liposoluble ingredient, still contains other compositions such as flavonoid, triterpenes, sterol.What belong to quinone, ketone type structure in the Diterpenes composition has Tanshinone I, an II
A, II
B, V, VI, cryptotanshinone, iso tanshinone I, II, II
B, dihydrotanshinone I etc.Water miscible liposoluble ingredient has depside that danshensu, protocatechualdehyde, protocatechuic acid, caffeic acid and danshensu and caffeinic derivant or dimer esterification form such as salvianolic acid A, B, C, D, E, G, alkannic acid B, rosmarinic acid, rosmarinic acid methyl ester etc.
Tanshinone I I
AIt is one of representative composition of Radix Salviae Miltiorrhizae Diterpenes blood circulation promoting and blood stasis dispelling.Modern pharmacological research shows Tanshinone I I
AMonomeric pharmacological action mainly contains: expeirmental myocardial ischemia and reperfusion injury are had the improvement effect; Influence experiment to cardiac electrophysiology shows calcium antagonism; The antiplatelet aggregative activity anti thrombotic action.On behalf of the composition cryptotanshinone, the Radix Salviae Miltiorrhizae Diterpenes another have the antibacterial and estrogen-like effects of antiinflammatory.
The pharmacological action of water-soluble phenolic acids monomeric compound mainly contains in the Radix Salviae Miltiorrhizae: anti thrombotic action comprises antiplatelet effects, anticoagulation, anti-thrombosis function; Improve the blood circulation effect: the anti-oxidative damage effect;
By multipath, the performance myocardium protecting action; The active two effective parts of blood circulation promoting and blood stasis dispelling has definite pharmacological research basis in the red rooted salvia, and is confirmed in long-term clinical practice.Therefore when the exploitation red sage formulation, not only should cure mainly, extract its effective site of reservation according to the prescription function; And should in moulding process, impose the preparation factor, improve the release of effective ingredient.
