Semi-quantifications of A. majus flowers profiles by using different methodologies based on: a total integrated peak area b normalized area, c single internal standard peak (1-phenylethanol), d NearestRT n-alkane abundance and e percentage abundance. Semi-quantifications were applied to raw data from day and night. Figures show the mean values of three samples for each compound and error bars indicate the standard error. Different letters indicate statistical differences between compounds during the day. Asterisks indicate statistical differences of individual compound between day and night
