Similarly, the determination of safranal by GC was in agreement with analysis by TLC and HPLC. Also, many normal phase HPLC methods are a carryover from TLC methods in which water-saturated organic phases are commonly used - a typical example being Butanol-acetic acid-water ( 4:1:5, upper phase). The lower phase was used as the stationary phase while the upper phase was used as the mobile phase in the head to tail elution mode. Also, many normal phase HPLC methods are a carryover from TLC methods in which water-saturated organic phases are commonly used - a typical example being Butanol-acetic acid-water ( 4:1:5, upper phase).
