摘　　要：从中草药麻黄、益母草中提取其中的生物碱,用瑞典产的2277型热活性检测仪测定了不同浓度的生物碱液对金黄色葡萄球菌代谢作用的热功率 时间曲线,计算出细菌生长的速率常数,建立了生长速率常数与药物浓度之间的关系,进而确定了药物的最佳抑菌浓度。The thermal power-time curves for metabolic action of staphylococcus aureus in alkaloid solutions with different conceutrations (extracted from traditional Chinese drugs-ephedra and leonurus heterophllus) were recorded using a 2277 thermal activity monitor (Sweden). The growth rate constants were calculated. The relationship between the growth constant (μ) and concentration of alkaloid solution (c) was established and the optimum concentrations were estimated.
