The identified constituents are listed in their order of elution.
RA indicates relative amount (peak area relative to the total peak area).
The extraction efficiency of NRR oil was over 95% within the 4 hours of distillation. In addition, the amount of extracted oil was % (). The values are in mean of three individual experiments (). The SD values were less than 5% of the mean, not shown for clarity.
