Bibliography:The metabolic activity of organisms can be measured by recording the heat output using microcalorimetry. In this paper, the total alkaloids in the traditional Chinese medicine Radix Aconiti Lateralis were extracted and applied to Eschenchia coil and Staphylococcus aureus. The effect of alkaloids on bacteda growth was studied by microcalorimetry. The power-time curves were plotted with a thermal activity monitor （TAM） air isothermal microcalorimeter and pa- rameters such as growth rate constant （p）, peak-time （Trn）, inhibitory ratio （I）, and enhancement ratio （E） were cal- culated. The relationships between the concentration of Aconitum alkaloids and p of E. coil or S. aureus were discussed. The results showed that Aconitum alkaloids had little effect on E. coil and had a potentially inhibitory effect on the growth of S. aureus.
