Legend: The data are presented as relative % for each component identified. RRI^a, relative retention index calculated based on retention of n-alkanes. RRI^b, relative retention indexes reported in the literature: ^# [28], ^@ [26]; ^ [29]; ** [30], *** [31,32], ^## [33]. % was calculated from flame ionization detector data. Trace amounts (t) were present at <0.1%. * Santolina epoxide was tentatively identified using Wiley and MassFinder mass spectra libraries and published RRI. All other compounds were identified by comparison with co-injected standards.
