RI: Retention index based on retention times of identified compounds, calculated from linear equation between each pair
of straight chain hydrocarbons (C5-C15).
2
ND: Not Detected. GC peaks for isoamyl acetate and 2-methylbutyl acetate
co-eluted. (Z,Z)-3,6-nonadienyl acetate identification was tentative: Mass spectral data was identical to those of
acetylated (Z,Z)-3,6-nonadienol.
