While erthrocyte, hemoglobin and Hela cell were under oxidative damage induced by the hydrogen peroxide (H2O2) or tert-butyl hydroperoxide on different concentrations of dihydromyricetin, hemolysis rate of erythrocyte and methemoglobin converted from hemoglobin was estimated by ultraviolet-visible absorption spectroscopy. Whereas mmalondialdehyde from erythrocyte was measured by thiobarbituric acid colorimetry, the cellular viability of Hela cell was examined using MTT 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide assay.

Results Twain-80 can increase the solubility. The dimethylsulfoxide, the sorbic acid and acetic acid chlorine can strengthen its bacteriostasis effect. To choice suitable antiseptic temperature and control antiseptic time may enhance furacilin liquid preparation stability. On the contrary, it may reduce the stability when mixing the antioxidants agents such as the sodium hyposulfite and the sodium bisulfite.

结果 吐温-80可增溶；二甲基亚砜、山梨酸和醋酸氯己定可增强其抑菌效果；选择适宜灭菌温度、控制灭菌时间可提高呋喃西林液体制剂的稳定性；加入硫代硫酸钠和亚硫酸氢钠做抗氧化剂则使其稳定性降低。
