Study on Optimization of Ethanol Reflux Extraction of Phenolic Acids from Salvia miltiorrhiza

The extraction technology of phenolic acid compounds from Salvia miltiorrhiza by ethanol reflux was studied. In this experiment, salvianolic acid B standard was used to make the standard curve. Single factor experiment and orthogonal experiment were used to study the extraction of different ethanol concentrations, reflux times and material-to-liquid ratios. The OD value of salvianolic acid compounds was measured with a spectrophotometer. The extraction rate of phenolic acid compounds under different extraction conditions was calculated through a regression equation, so as to obtain the optimal conditions for the ethanol reflux extraction process of Salvia miltiorrhiza. The experimental data can provide a reference for the ethanol reflux extraction process of salvianolic acids in the industry. According to the experiment, the extraction rate of phenolic acids in Salvia miltiorrhiza was the highest when the ethanol concentration was 60%, the reflux time was 1.5 hours, and the ratio of material-to-liquid was 1:10.

Research advances in antiplatelet activation of water soluble compounds in Salvia miltiorrhiza

Platelets are fragments of cytoplasm that are released from the mature megakaryocyte of the bone marrow.The main function of platelets is coagulation and hemostasis.Platelets play a central role in formation of pathological thrombosis.Many ischemic diseases are caused by excessive activa.tion of platelets,which can lead to thrombosis and death.Salvia miltiorrhiza Bunge,the dry roots and rhizomes of the Salvia miltiorrhiza plants,includes some water-soluble compounds,which play positive effects on diverse diseases such as neurodegenerative diseases,diabetic complications or cardiovas.cular diseases.In this paper,the components of the water-soluble in Salvia miltiorrhiza,as well as the applications in thrombotic diseases are summarized.The results show that water-soluble compounds include salvianolic acid A,salvianolic acid B,protocatechuic aldehyde,Danshensu,etc.The water-soluble compounds are applied to ischemic stroke,myocardial infarction and other diseases caused by thrombus.We also discussed the mechanisms of water-soluble compounds on the platelets based on our research results and the data obtained from references.The results indicate that water soluble compounds in Salvia miltiorrhiza play the antiplatelet and antithrombotic effects via different mechanisms,for example,salvianolic acid A inhibits platelet aggregation without promoting bleeding by increasing cAMP,inhibiting phosphoinositide 3-kinase(PI3K) and affecting GPCRs(G protein-coupled receptors) signaling path.ways;salvianolic acid B inhibit platelets as a P2Y12 antagonist and PDE inhibitor;Danshensu inhibits platelet activity may be related to inhibition of calcium influx.In conclusion,thrombotic diseases seriously affect human life and health.The existing antiplatelet drugs have some disadvantages.For example,aspirin may cause intracranial hemorrhage,and clopidogrel may play a slower role.Salvia miltiorrhiza as a traditional Chinese medicine has positive pharmacological activity and exerts antiplatelet aggrega.tion through different mechanisms.In the future,we will develop the new drugs which prevent and treat thrombotic diseases with the further study of the pharmacological effects and mechanisms of Salvia miltiorrhiza.

Microwave digestion polarography for determining seven trace elements in Salvia Miltiorrhiza Root and compound Salvia Miltiorrhiza Root injection simultaneously

The sensitive second derivative waves of Cu(Ⅱ),Pb(Ⅱ),Cd(Ⅱ),Ni(Ⅱ),Zn(Ⅱ),Fe(Ⅱ)and Mn(Ⅱ),forming in the substrate solution(pH=9.26)consisting of ammonia,ammonium chlorid,gelatin and ascorbic acid were researched.The peak potentials of the polarographic waves of the seven ions are at about 0.48,0.63,0.79,1.04,1.28,1.44 and 1.60 V respectively.Combining with microwave technique,a new method for the simultaneous determination of the seven trace elements in Chinese traditional medicine was developed.The method is easy to operate,rapid,simple and convenient.When the signal-to-noise rate equals 3,the detection limits of Cu,Pb,Cd,Ni,Zn,Fe and Mn are 4.2×10 3,5.3×10 3,2.1×10 3,5.8×10 4,3.0×10 3,7.7×10 4 and 1.1×10 3 μg/mL respectively.Well linear relationships exist between the concentrations and the peak currents when Cu,Pb,Cd,Ni,Zn,Fe and Mn concentrations are within 8.5×10 3 10,9.7×10 3 10,4.5×10 3 10,1.2×10 3 10,6.4×10 3 10,1.5×10 3 10 and 2.8×10 3 10 μg/mL,respectively.The method has been used to the simultaneous determination of the seven trace elements in Salvia Miltiorrhiza Root and compound Salvia Miltiorrhiza Root injection,the relative standard deviations(RSDs)of the Cu,Pb,Cd,Ni,Zn,Fe and Mn in the two medicines are 3.9% and 5.8%,4.0% and 4.1%,4.3% and 5.7%,4.9% and 5.3%,4.4% and 4.7%,3.5% and 4.0%,0.51% and 2.8%,respectively;the comparisons of the determination results with the values obtained by the standard method indicate that the presented method has very well veracity.
