Salvianolic acid B (SAB, Sal B) is the representative component of phenolic acids derived from the dried root and rhizome ofSalvia miltiorrhizaBge (Labiatae) which has been used widely and successfully in Asian countries for clinical therapy of various vascular disturbance-related diseases for hundreds of years. However, its exact cardioprotective components and the underlying mechanism for therapeutic basis are still poorly understood. This paper discussed and elucidated the underlying biological mechanisms and pharmacology of Sal B and their potential cardioprotective effects.

The stability of salvianolic acid B and total phenolic acids from Salvia miltiorrhiza in water solutions at different temperatures, in buffered aqueous solutions at different pHs and in biological fluids, including simulated gastric and intestinal fluids, were investigated in vitro. The results showed that the degradation of salvianolic acid B was pH- and temperature-dependent. Furthermore, structures of the degradation products of salvianolic acid B and total phenolic acids were elucidated by liquid chromatography-electrospray ion trap mass spectrometry and analysis of the degraded solutions revealed seventeen degradation products. The possible degradation pathway of salvianolic acid B is proposed.

Background: Although chromatography and spectrometry based methods have been used to analyse phenolic acids in Chinese traditional medicine Salvia miltiorrhiza Bunge (SMB), quantitative nuclear magnetic resonance (qNMR) has never previously been used to analyse fresh SMB root extracts. Objective: To establish a fast and simple method of quantitating danshensu, lithospermic acid, rosmarinic acid and salvianolic acid B content in fresh SMB root using 1H-NMR spectroscopy. Method: Fresh SMB root were extracted using a 70% methanol aqueous solution and quantitatively analysed for danshensu, lithospermic acid, rosmarinic acid and salvianolic acid B using 1H-NMR spectroscopy. Different internal standards were compared and the results were validated using high performance liquid chromatography. Results: The established method was accurate and precise with good recovery. The LOD and LOQ indicated the excellent sensitivity of the method. The robustness was testified by modification of four different parameters, and the differences among each parameter were all less than 2%. Conclusion: qNMR offers a fast, reliable and accurate method of identifying and quantifying danshensu, lithospermic acid, rosmarinic acid and salvianolic acid B in fresh SMB root extracts.

Abstract Aim of the study: Salvianolic acid B(Sal B) as a natural compound extracted from Salvia miltiorrhiza, has been extensively used to protect cardiomyocytes from myocardial ischemia. Although Sal B has shown evident effects on cardiovascular diseases, the detailed mechanism is still unclear as yet. Herein, we intended to explorethe protective effects of Sal B on myocardial ischemic injury and the underlying mechanism. Methods and Results: Western blotting, immunofluorescence assay, flow cytometry and lentiviral transfection were performed. The mice with myocardial ischemic injury were intravenously given 10 mg/kg Sal B once daily for seven days, and then H9c2 cells were treated with Sal B (20, 40, 80 μmol/L). Sal B treatment protected cardiomyocytes from myocardial ischemia through relieving apoptosis. Transmission electron microscopy and fluorescence microscopy exhibited that Sal B significantly increased autophagic lysosomes and vacuoles in H9c2 cells. Administration with Sal B significantly up-regulated the expressions of autophagy-related factors such as LC3, Atg5 and Beclin 1 in H9c2 cells and myocardial tissues. The beneficial autophagic changes induced by Sal B were abrogated through pharmacological inhibition. Conclusions: This study provides a molecular mechanism by which Sal B potently inhibits apoptosis and oxidative stress upon myocardial ischemia by activating the AMPK-autophagy pathway. Sal B is a potential agent for treating myocardial ischemia.

Survival and outcome of cardiac arrest (CA) are dismal despite improvements in cardiopulmonary resuscitation (CPR). Salvianolic acid B (Sal B), extracted from Salvia miltiorrhiza, has been investigated for its cardioprotective properties in cardiac remodeling and ischemic heart disease, but less is known about its role in CA. The aim of this study was to learn whether Sal B improves cardiac and neurologic outcomes after CA/CPR in mice. Female C57BL/6 mice were subjected to eight minutes of CA induced by an intravenous injection of potassium chloride (KCl), followed by CPR. After 30 seconds of CPR, mice were blindly randomized to receive either Sal B (20 mg/kg) or vehicle (normal saline) intravenously. Hemodynamic variables and indices of left ventricular function were determined before CA and within three hours after CPR, the early postresuscitation period. Sal B administration resulted in a remarkable decrease in the time required for the return of spontaneous circulation (ROSC) in animals that successfully resuscitated compared to the vehicle-treated mice. Myocardial performance, including cardiac output and left ventricular systolic (dp/dtmax) and diastolic (dp/dtmin) function, was clearly ameliorated within three hours of ROSC in the Sal B-treated mice. Moreover, Sal B inhibited CA/CPR-induced cardiomyocyte apoptosis and preserved mitochondrial morphology and function. Mechanistically, Sal B dramatically promoted Nrf2 nuclear translocation through the downregulation of Keap1, which resulted in the expression of antioxidant enzymes, including HO-1 and NQO1, thereby counteracted the oxidative damage in response to CA/CPR. The aforementioned antiapoptotic and antioxidant effects of Sal B were impaired in the setting of gene silencing of Nrf2 with siRNA in vitro model. These improvements were associated with better neurological function and increased survival rate (75% vs. 40%, p<0.05) up to 72 hours postresuscitation. Our findings suggest that the administration of Sal B improved cardiac function and neurological outcomes in a murine model of CA via activating the Nrf2 antioxidant signaling pathway, which may represent a novel therapeutic strategy for the treatment of CA.

Oxidative stress is considered one of the factors that cause dysfunction and damage of neurons, causing diseases such as amyotrophic lateral sclerosis (ALS), Alzheimer’s disease (AD), and Parkinson’s disease (PD).Recently, natural antioxidant sources have emerged as one of the main research areas for the discovery of potential neuroprotectants that can be used to treat neurological diseases. In this research, we assessed the neuroprotective effect of a 70% ethanol Salvia miltiorrhiza Radix (SMR) extract and five of its constituent compounds (tanshinone IIA, caffeic acid, salvianolic acid B, rosmarinic acid, and salvianic acid A) in HT-22 hippocampal cells. The experimental data showed that most samples were effective in attenuating the cytotoxicity caused by glutamate in HT-22 cells, except for rosmarinic acid and salvianolic acid B. Of the compounds tested, tanshinone IIA (TS-IIA) exerted the strongest effect in protecting HT-22 cells against glutamate neurotoxin. Treatment with 400 nM TS-IIA restored HT-22 cell viability almost completely. TS-IIA prevented glutamate-induced oxytosis by abating the accumulation of calcium influx, reactive oxygen species, and phosphorylation of mitogen-activated protein kinases. Moreover, TS-IIA inhibited glutamate-induced cytotoxicity by reducing the activation and phosphorylation of p53, as well as by stimulating Akt expression. This research suggested that TS-IIA is a potential neuroprotective component of SMR, with the ability to protect against neuronal cell death induced by excessive amounts of glutamate.
