Comparison on the Chemical Constituents and Antioxidant Activity of Volatile oil of Alpiniae Oxyphyllae Fructus between the Raw and the Salt
摘要
Abstract
Objective:To compare the difference of chemical constituents and antioxidant activity of volatile oil of Alpiniae Oxyphyllae Fructus between the raw and the salt, and to investigate the impact on the chemical compounds and antioxidant activity of volatile oil of Alpiniae Oxyphyllae Fructus after salt processing.Meth-ods:The volatile oil of Alpiniae Oxyphyllae Fructus was extracted by steam distillation, and its chemical con-stituents were analyzed and identified by GC-MS, and the content of Nootkatone was determined by GC,and the antioxidant effect was determined by DPPH method.Results:77 chemical compounds were detected and 38 of them were identified in the volatile oil of Alpiniae Oxyphyllae Fructus, and 94 chemical compounds were detected and 34 of them were identified in the volatile oil of Alpiniae Oxyphyllae Fructus after salt processing. 36 common chemical compounds were detected in both the raw and the salt.The content of nootkatone was 0.9659mg/g, 0.6498mg/g in the raw and the salt.Conclusion:The chemical constituents and antioxidant ac-tivity of volatile oil of Alpiniae Oxyphyllae Fructus all have a great change after salt processing .The study pro-vides a basis for revealing the mechanism of salt processing of Alpiniae Oxyphyllae Fructus.关键词
