HS-SPME-GC-MS Analysis on Volatile Components in Various Processed Products of Achyranthes Bidenta-tae Radix / 中国药师

ABSTRACT

Objective: To analyze and compare the difference in volatile components in Achyranthesbidentatae Radix, salt-pro-cessed product of Achyranthes bidentatae Radix and wine-processed product of Achyranthes bidentatae Radix. Methods:Headspace sol-id-phase microextraction ( HS-SPME) was used to extract the volatile components from Achyranthes bidentatae Radix and the two pro-cessed product of Achyranthes bidentatae radix. The chemical compositions were analyzed by gas chromatography-mass spectrometry ( GC-MS) , and their relative mass fraction of each component was determined by an area normalization method. Results:A total of 38 chemical components were identified, and 23, 16 and 15 components were respectively identified from Achyranthes bidentatae Radix, the salt-processed product of Achyranthes bidentatae Radix and the wine-processed product of Achyranthes bidentatae Radix accounted for 79. 14%, 49. 80% and 44. 57% of the total content of volatile components, respectively. There were 4 types of common volatile chemical constituents in the three products. Compared with Achyranthes bidentatae Radix, 10 types of new compounds were produced and 17 types of old compounds disappeared in the salt-processed product, and 9 types of new compounds were produced and 17 types of old compounds disappeared in the wine-processed product. Conclusion:Different processing methods have some influence on the type and the content of the volatile components in Achyranthes bidentatae Radix. Using HS-SPME-GC-MS combination technique can quickly and effectively obtain the volatile components information for Achyranthes bidentatae Radix, which can provide scientific reference for the quality evaluation and application of the processed products of Achyranthes bidentatae Radix.
