Research of chromatographic spectra of retention oflight components of headspace of medicinal herbs ”Lavandula Spica”, ”Menthapiperita L.”, ”Artemisia dracunculus L.”

On the example of research of chromatographic spectra of retention of light components of headspace of medicinal herbs of lavender (Lavandula Spica), peppermint (Mentha piperita L.) and estragon (tarragon herb, Artemisia dracunculus L.), the possibility of express estimate of their authenticity per totality of retention index of light components in the mode of linear programming of temperature on capillary column with polydimethylsiloxane stationary phase with the use of present in the laboratories available gas chromatographic equipment with flame ionization detector is shown.
