METHODS The volatile components of C. chinensis ，C. chinensis stir-frying with saltwater ， C. chinensis stir-frying with wine were identified by headspace solid phase microextraction combined with gas chromatography- mass spectrometry. The relative percentage of each component was calculated by area normalization method. The PCA was conducted by using SPSS 21.0 software. RESULTS A total of 117 compounds were identified from C. chinensis ，C. chinensis stir-frying with saltwater and C. chinensis stir-frying with wine ，of which 68 compounds were identified from C. chinensis （relative percentage of 92.41％），such as phytone ，2-methoxy-3-（2-propenl）phenol，n-pentadecane，β-caryophyllene. Sixty compounds （relative percentage of 89.41％） were identified from C. chinensis stir-frying with saltwater ，such as maltol ，2，3-dihydro- benzofuran，4-vinyl-2-methoxyphenol. Fifty-eight compounds （relative percentage of 87.02％）were identified from C. chinensis stir-frying with wine ，such as phenylethanol ，β-caryophyllene，macrocarehe D. There were 24 common components in the three ， and relative percentage of them were 38.56％，30.61％，33.07％，respectively. After processing ，there were 49 new components ， such as furfural ，n-hexanoic acid ，caryophyllene oxide. The results of PCA showed that the cumulative contribution rate of the former two principal components was 100％ ；comprehensive score of volatile components of C. chinensis was the highest ， followed by C. chinensis stir-frying with wine and C. chinensis stir-frying with saltwater. CONCLUSIONS The quality of volatile components in C. chinensis is good ；the volatile components in processed products are more than those in C. chinensis .
RESUMO
ObjectiveTaking Chuanxiong Chatiaosan prescription as the carrier， by comparing the differences of volatile components in Chuanxiong Rhizoma with single decoction pieces and compatible prescription of different decoction pieces， the differences of material basic connotation of different formulations of Chuanxiong Chatiaosan were revealed from the aspects of processing （raw and wine-processed products）， compound compatibility and dosage form （powder and decoction）. MethodThe volatile oil was extracted from different decoction pieces of Chuanxiong Rhizoma， Chuanxiong Chatiaosan and its decoction with different decoction pieces of Chuanxiong Rhizoma by steam distillation， the main components and their relative contents were identified by gas chromatography-mass spectrometry （GC-MS）. ResultA total of 25 volatile components were identified from different processed products of Chuanxiong Rhizoma， including 11 monoterpenoids， 4 phenols， 3 sesquiterpenoids， 3 phthalides， 2 ketones and 2 olefins， the contents of α-pinene， β-pinene， 3-butylphthalide and others increased after the raw products was processed with wine. A total of 85 constituents were identified from Chuanxiong Chatiaosan with different decoction pieces， including 31 monoterpenoids， 23 sesquiterpenoids， 5 alcohols， 5 aldehydes， 4 phenols， 4 phthalides， 3 ethers， 3 ketones， 1 olefin， 1 organic acid， 2 esters and 3 other compounds. A total of 22 components， including 9 sesquiterpenoids， 3 phthalides， 2 phenols， 6 monoterpenoids， 1 aldehyde and 1 alkane， were identified from the decoction of Chuanxiong Chatiaosan with different processed products. ConclusionThere was no significant difference in the composition between raw products and wine-processed products of Chuanxiong Rhizoma either in single decoction pieces or in compatibility prescription， but the relative content changed to some extent， and the wine-processed products was the most obvious. There was a great difference in the composition of volatile components between the Chuanxiong Chatiaosan and its decoction. The volatile components， such as isopulegol， isocalamendiol and safrole， were not found in the decoction. Components in Chuanxiong Rhizoma processed with wine will change with the addition of yellow rice wine， and volatile components can reflect the difference between decoction pieces and prescriptions of the wine-processed products.
