Compounds listed in elution order through the capillary column HP5. ^bRI Calculated: The retention index (RI) was calculated using a homologous n-alkane series C7 to C40 in the capillary column (HP5). ^cThe identification of compounds was based on the comparison of mass spectra to Wiley 275 spectrum library. ^dliterature retention index (RI): Adams, 2017 and Silva, Pott, et al. (2010) for Isospathulenol; Lawal and Oyedelji (2009) for Caryophylla-3,8(13)-dien-5β-ol; Relative area (%): percentage of the area occupied by compounds within the chromatogram; n.i.: non-identified; t: traces; IM: identification methods. For the analysis, only compounds with a relative area (%) greater than 1.0% were considered.
