The aerial parts of Salvia miltiorrhiza Bunge, as the non-medicinal parts, are always discarded during harvesting, resulting in a huge waste of resources and environmental pressure. Due to the high flavonoid content and their antioxidant activities characteristics, the aerial parts of S. miltiorrhiza can be developed into natural antioxidants and used in foods. A high-speed counter-current chromatography (HSCCC) method, using a two-phase solvent system composed of tert-butyl methyl ether/n-butanol/acetonitrile/water (3:1:1:20, v/v), was the first to successfully isolate five flavonoids from the aerial parts of S. miltiorrhiza in one attempt, and separately categorized as rutin (1), isoquercitrin (2), kaempferol-3-O-α-l-rhamnopyranosyl-(1→6)-β-d-glucopyranoside (3), kaempferol-3-O-β-d-glucopyranoside (4) and apigenin-7-O-β-d-glucopyranoside (5) after identification. The purities of these plant isolates were 97.3%, 99.5%, 92.8%, 98.1% and 98.7%, respectively. All the flavonoids were identified by HR-ESI-MS, 1D and 2D NMR. Compounds 3 and 5 were firstly isolated from the plant of S. miltiorrhiza. Results from antioxidant assays showed that rutin (1) and isoquercitrin (2) had higher antioxidant capacities compared to L-ascorbic acid as the positive control.

Abstract Objectives Increasing attention has been paid to a range of botanical food supplement that help to maintain vascular health. Multiple components in botanical foods are expected to be working in concert with various targets. In a previous our animal study, Phellinus baumii and Salvia miltiorrhiza Bunge (PS) ameliorated endothelial and vascular dysfunction in a platelet activation rat model. This study aimed to provide the components, target molecules, phenotypes, signaling pathways, and investigate the mechanism of PS on vascular health. Methods Network biology analysis was based on the data from two clinical trials. The first clinical trial was performed in healthy subjects using high-fat-induced vascular dysfunction model. The second clinical trial was performed in healthy smokers. Differential markers obtained from clinical data, Affymetrix microarray, metabolomics, together with ingredient of PS, were mapped onto the network platform termed the context-oriented directed associations. A network of “component-target-phenotype-pathway” was constructed. Results The resulting vascular health network demonstrates that the components of PS are linked various target molecules for adhesion molecule production, platelet activation, endothelial inflammation, vascular dilation, and mitochondrial metabolism and detoxification, implicated with various metabolic pathways. Conclusions Using network biology methods, this study revealed the components and their target molecules, phenotypes, signaling pathways and provided wider information to support the synergistic mechanisms of PS on vascular health. Funding Sources This research was funded by the Bio & Medical Technology Development Program of the National Research Foundation funded by the Ministry of Science & ICT and the BK21PLUS of the National Research Foundation.
