RT retention time (min). RIlit retention index (iu) reported in the literature for 5% phenyl polysilphenylene-siloxane GC column. RIcalc retention index obtained through the modulated chromatogram. Ref. RIlit retention index bibliography found in the literature for 5% phenyl polysilphenylene-siloxane GC column. Extract (mg/mL), phytosomes (mg/mL). nd = Not detected. Non-polar retention index (n-alkane scale). The values are the mean ± SD (n = 3). Fragment ions (m/z) of unknown 1: 218 (100), 203, 219, 69, 95, 426 [M+], 411.4. Unknown 2: 189 (100, 95,207,93,135, 426 [M+], 411.4.
