摘　　要：从中药茵陈、大黄、麻黄中提取挥发油作用于大肠杆菌的生长,微量热法测定了不同浓度的挥发油药液对其生长的热功率-时间曲线,运用Logistic方程求出生长速率常数,通过计算机模拟建立了生长速率常数与药物浓度之间的关系,实验表明三种挥发油对大肠杆菌的生长都具有抑制作用,根据拟和曲线确定理论最小抑菌浓度,结果表明大黄挥发油的抑菌效果最好.in this paper, the antibacterial effects of volatile oils at different concentrations on E. coli were investigated by microcalorimetry, and on the basis of the generalized Logistic equation, P - t curves equation were derived for calculating the rate constants. μ -c equations were established and results obtained volatile oils can inhibit bacterial. The minimum inhibitory contentration was calculated. The Rheum oil is the best natural antibiotics.
