Actovegin (AC), purified from veins of young veins, consists mainly of inorganic ions and small organic molecules. In this paper, its biochemical properties and pharmacodynamics were studied. The results showed that AC dry matter weight was 40 mg / ml, AC potassium ions 1.4 8 ± 0.26 (mg / ml) and sodium ions 10.92 ± 1.4 7 ( mg / ml), chloride of 15.92 ± 1.98 (mg / ml), polypeptide of 1.79 ± 0.2 (mg / ml), amino acid of 1.07 ± 0.16 (mg / ml) and glucose of 2.01 ± 0. 32 (mg / ml). AC had the biological activity of stimulating the mitochondrial respiration of guinea pig liver homogenate (the respiratory activity QO2 was 3.1 μl / mg · h and the stimulation index SI was 2.6). AC pharmacodynamic studies have shown that AC can promote the transport of blood glucose to brain tissue and promote glucose aerobic metabolism in brain tissue to prolong the survival time of mice and improve brain function under global cerebral ischemia and hypobaric hypoxia Tissue ischemia, hypoxia, can be used for cerebral ischemia, hypoxia and other diseases
