Solid-phase microextraction-gas chromatographic-mass spectrometric analysis of volatile compounds from Curcuma wenyujin Y.H. Chen et C. Ling.

A solid-phase microextraction coupled with gas chromatography-mass spectrometry (SPME-GC-MS) for analysis of the volatile compounds from Curcuma wenyujin Y.H. Chen et C. Ling is described. SPME parameters (fiber type, extraction temperature and time, headspace volume and desorption time) and GC conditions were tested. The powdered sample of C. wenyujin Y.H. Chen et C. Ling was directly analyzed by SPME-GC-MS and 72 compounds were identified. The results from SPME-GC-MS were compared with those obtained from steam distillation gas chromatography-mass spectrometry (SD-GC-MS) with a good agreement. The results show that SPME-GC-MS method is a fast, simple and efficient way for the analysis of volatile components from traditional Chinese medicines (TCMs).
