| Abstract: | The head space-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS) was used to identify the volatile components in Herba Lycopi.The operation parameters of HS-SPME were investigated(fiber heads,the sample equilibrium time,extraction temperature,extraction time and desorption time),and the determination results were compared with the traditional steam distillation(SD) and supercritical CO2 extraction method.The GC-MS analysis results showed that 58 compositions were identified and... |
