藥理活性: Antiarrhythmic （rat arrhythmia caused by BaCl2）;inhibits fatigue; antiviral; inhibits replication of HSV-1; bidirectional action to blood pressure （mus, first increases ａnd then lowers blood pressure, whileheart rate slows）; calcium antagonist; increases blood pressure （injecting0.3μL into lateral area of rat hypothalamus, average arteriotony noticeablyrising）; antioxidant （rat hepatic homogenate, caused by H2O2, IC50 =644.8μg/mL）; cAMP phosphodiesterase inhibitor （in vitro, IC50 = 137μmol/L）;antihypercholesterolemic （reduces the level of cholesterol in serum）; promotesbiosynthesis of DNA, protein ａnd lipid （murine marrow cells）; enhancescytotoxic effects of daunomycin ａnd vincaleucoblastine; promotes plasma

secretion of corticosterone （ED50 = 112μmol/kg）; liver ａnd nerve protectant;reduces uterine contraction （gpg, in vitro, caused by acetylcholine）;vasodilator （dog）; anti-inflammatory （modulator of cytokine network: inhibits IC50 = 56.5μmol/Land 51.3μmol/L, respectively）; antinociception （i.t.injected 0.7μg substance P-induced pain model, EC = 50μg i.t.）; neurite

outgrowth enhancer （hmn neuroblastoma SK-N-SH cells, 100μmol/L, total length of neurites = 149.3μm, number of varicosity per cell = 0.93, p<0.05;control, total length of neurites = 45.3μm, number of varicosity per cell =0.10）; hepatoprotective （inhibits activation of macrophages, inhibitsincrease in sALT ａnd sAST levels, in vivo, D-GalN/LPS-induced liver injury in mouse, 100mg/kg ip for sALT, InRt = 33%; 100mg/kg ip for sAST, InRt =40%; control Hydrocortisone, 20mg/kg ip for sALT, InRt = 99%; 20mg/kg ipfor sAST, InRt = 97%）.
