Abstract

Abstract: Ultra-high-performance liquid chromatography（UPLC）,flame atomic absorption spectroscopy and ICP-MS were used to measure the contents of 6-gingerol,Cu,Zn,Fe,Mn,Pb,Cd and Cr in authentic medicinal Maliu ginger（Jun-ginger and Pao-ginger）with different processing methods. SPSS 22.0 was utilized for analyzing the similarities and differences in various components between the two. Results showed that the content of 6-gingerol in Jun-ginger was found to be （2.34±1.47） mg/g, while it was measured as （1.64±1.27） mg/g in Pao-ginger. The metal contents were as follows：Fe（102.77±30.37） mg/kg,Zn（19.56±9.92） mg/kg,Cu（11.94±1.34）,Mn（316.93±202.90） mg/kg,Pb（0.61±0.40） mg/kg,Cd（0.23±0.20） mg/kg,Cr（0.85±0.20） mg/kg in Jun-ginger and Fe(130.74±46.47) mg/kg,Zn(15.19±7.75) mg/kg,Cu(11.62±2.50) mg/kg,Mn(245.06±206.22) mg/kg,Pb(0.62±0.66) mg/kg,Cd(0.17±0.15) mg/kg,Cr(0.72±0.16) mg/kg in Pao-ginger respectively. Under two different processing methods the content of 6-gingerol in Maliu ginger was different, with the content in Jun-ginger higher than that in Pao-ginger（P<0.05）.
