【摘要】 [Objective]To analyze the chemical components in ethanol extracts of RHIZOMA ZINGIBERIS RECENS from different producing areas and to assay the content of 6-gingerol. [Method]GC-MS analysis and HPLC method were respectively adopted to analyze the chemical components in ethanol extracts and assay the content of 6-gingerol. [Result]39,44,45,49 and 44 compounds were respectively identified from RHIZOMA ZINGIBERIS RECENS that was collected from 5 producing areas,mainly including gingerol ( accounted for 30% of total essential oils) ,shogaols,paradols and zingerone. Because of different producing areas,there were significant differences regarding chemical components and their relative contents in tested samples. 6-Gingerol presented a good linearity with peak area between the concentration of 0.024 8 and 0.124 mg/ml ( r = 0.996 6,n =5) . The average recovery was 99.20% with the RSD of 1.26%. [Conclusion]GC-MS was quick,simple,convenient and effective to analyze the composition of ethanol extracts. HPLC method was simple,reliable and reproducible to determine the content of 6-gingerol.
