General description

trans-β-Farnesene is the main active constituent of the alarm pheromone in the aphid species. It causes behavioral responses, such as kicking, discontinuation of feeding, moving away, or dropping down among them.

Application

This analytical standard can also be used as follows:

  • Secondary metabolite profiling of various plant parts collected from 82 plants belonging to 21 different cannabis strains using gas chromatography-mass spectrometry (GC-MS) for sterols and terpenoids (mono-, sesqui-, tri-), and high-performance liquid chromatography (HPLC) with UV and mass spectrometric (MS) detection for flavonoids
  • Gas chromatographic analysis of a total of 163 compounds in the essential oil samples extracted from the leaves and flowers of Lantana camara, in combination with detection techniques of mass spectrometry (MS) and flame ionization detection (FID)
  • Simultaneous determination of 49 compounds from the essential oil samples obtained from the methanolic extracts of dried leaves and flowers of C. macropodum by GC-FID and GC-MS methods
  • Identification and quantification of 31 volatile organic compounds from the flowers of P. Nobby’s Pacific Sunset using DVB/CAR/PDMS fibers in the solid-phase microextraction (SPME) technique for the sample enrichment followed by their GC-MS analysis
