| Abstract: | Camphor in sassafras oil was determined by capillary column-gas chromatograhy using hydrogen flame-ionization detector. Absolute alcohol was used as solvent for the sample and cyclohexanone was used as inner standard. Optimum conditions of analysis were studied and described in detail. Linear relationship between the values of A_i/A_s and m_i/m_s was held and its linear regression equation was given as follows (Note: A_i/A_s is the peak area ratio of sample to standard, and m_i/m_s is the ratio of the corresponding mass of sample to standard.): Y=0 8638X+0.0128 (r=0.9997). By the analysis of a same sample w (camphor)=0.97%] for 7 repeated determinations, the standard deviation (S) and RSD were found to be 0.023% and 2.37% respectively. Recovery test performed by standard addition method gave values in the range of 96.7% to 103.8%. |
