- W2387157069 abstract "Objective:To explore a characteristic chemical marker of Alpinia oxyphylla(A.oxyphylla)and to establish a method to determine the contents of nootkatone,tectochrysis and yakuchinone A in fruit of A.oxyphyllacollected from different sources.Method:The contents of nootkatone,tectochrysis and yakuchinone A were determined by SPE-HPLC.HPLC analysis was made on a C6-phenyl column(4.6mm ×250mm,5μm)with acetonitrile and water.The detection wavelength was 240 nm.Results:The HPLC method showed good linearity,precision and stability.The average recovery rates of three compounds were 98.61%to 99.98%.The content of nootkatone was similar at different sources.The contents of tectochrysis and yakuchinone A showed obvious difference among the plants collected from different sources.The content of yakuchinone A was high at Guangdong and Guangxi harvest zone and the content of tectochrysis was high at Hainan harvest zone.Conclusion:The method is accurate and reliable.It is appropriate for the quantitative determination of nootkatone,tectochrysin and yakuchinone A in A.oxyphylla and its production." @default.
