ABSTRACT
Objective:
To establish a new method for determination of ? pinene in Folium Pini.Method:
The contents of ? pinene were determined by high performance capillary gas chromatography with sequential increase of temperature programming.Results:
The calibration curve showed good linearity over the range of 0.424 2.12?g( r =0.9999). The average recovery was 97.9% and the relative standard deviation was 2.9%( n =5), and it was found that the contents of ? pinene in dry herbs were markedly different from the contents in fresh herbs.Conclusion:
The method is simple, and accurate with a good reproducibility and can be applied as quantitative analysis method for Folium Pini.
