Using a TAM air microcalorimetric system, the influence of different extractions from Radix Isatidis on Escherichia coli growth was investigated at 37 ℃ by microcalorimetry. In accordance with the thermogenic curves and parameters, the potential pharmacological action of decoction and its five bioactive parts was analyzed from the point of view of traditional Chinese medicinal (TCM) theory to screen the best extraction technology and the strongest antibacterial parts of Radix Isatidis. Meanwhile, the minimum inhibitory concentration of the strongest antibacterial parts of Radix Isatidis against Escherichia coli growth was obtained by a tube dilution method. The results show that microcalorimetry can be used to screen the extraction technology and bioactive parts of Radix Isatidis, furthermore to provide some suggestions for the study of TCM.
