Establishment the fingerprints of Phyla nodiflora by electronic nose (e-nose)

The consistency of phytochemical profile might be affected by different geography conditions and post-growth factors. Thus, a systematic quality criterion for controlling the quality is imperative. Application of electronic nose (e-nose) based on fast GC system is one of the selected method and it allows identification of volatile organic compounds fingerprints. Phyla nodiflora is a perennial herbs containing various chemical constituents, such as flavonoids, monoterpenes, sesquiterpenes, triterpenoids and volatiles, and with herbal and minty odour. Althought, the HPLC-fingerprints of P. nodiflora has been figured out the odour-profile of this plant has not been investigated. In this present study, the preliminary analytic method will be discussed. To date, the e-nose chromatograms of the volatile complex of P. nodiflora indicated that 1-octen-3-one, limonene, δ-nonalactone might contribute the odour of P. nodiflora. The appropriate analytic methods to indentify constitutions and establish the complete fingerprints of P. nodiflora by e-nose will be studied continually.
