Salvia miltiorrhiza (SAL) and Panax notoginseng (PNS) are widely used in treating of ischemic stroke. However, it is unknown which components of SAL and PNS protect brain microvascular pericytes after an ischemic stroke. We evaluated the protective effects and mechanisms of SAL and PNS components in pericytes subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Pericytes were subjected to OGD/R. Cell Counting Kit-8 (CCK-8) was used to evaluate cell viability. ROS and SOD kits were used to detect oxidative stress. Flow cytometry was performed to analyze cell apoptosis. To evaluate cell migration, a scratch assay was performed. Expression of cleaved caspase-3, Bcl-2, Bax, VEGF, Ang-1, PDGFR-β, PI3K/AKT/mTOR, and JNK/ERK/P38 signaling pathways were identified using western blot. The results revealed that salvianolic acid B (Sal B), salvianolic acid D (Sal D), notoginsenoside R1 (R1), ginsenoside Rb1 (Rb1), and ginsenoside Rg1 (Rg1) increased the cell viability of pericytes subjected to OGD/R, reduced the level of ROS, and increased the expression of SOD. The components reduced cell apoptosis, increased the protein level of Bcl-2/Bax, reduced the level of cleaved caspase-3/caspase-3, increased cell migration, and enhanced the levels of Ang-1, PDGFR-β, and VEGF. The components could activate PI3K/AKT/mTOR pathway while inhibiting the JNK/ERK/P38 pathway. Studies found that Sal B, Sal D, R1, Rb1, and Rg1 inhibited oxidative stress and apoptosis while increasing the release of pro-angiogenic regulators of pericytes related to the PI3K/AKT/mTOR and JNK/ERK/P38 signaling pathways. This provides a potential foundation for developing monomeric drugs for treating ischemic stroke.
