    Abstract: 本專題研究利用HPLC-UV/Vis 同時測定化妝品中四種酚類化合
    物Chlorogenic acid(以下簡稱:Ch)、Caffeic acid(以下簡稱:Ca)、
    Ellagic acid (以下簡稱:EA)and Ferulic acid(以下簡稱:FA)之
    安定性。實驗所探討出的沖提液為移動相,能使這四種分析物在11
    分鐘以內分離並定量,沖提液條件為:Acetonitrile19%+MeOH10%+
    H2O.pH=2.5。以此方法所得之分析物檢量線線性關係r 值在0.999 以
    上、再現性及穩定性之RSD%在3%以下且分離度在2 以上,並利用
    Methanol 萃取模擬樣品、實際樣品中的分析物,結果以Ellagic acid
    最為安定,其他的酚類成份濃度則隨著時間遞減,顯示相當的不安定。
