中文摘要 | 本研究係利用高效液相層析法,同時分析衛生署公告得添加於化粧品中之四種美白成分Magnesiumascorby1 phosphate 、Ascorbylglucoside、 Kojic acid、Arbutin及不得添加之Hydroquinone (對苯二酚) 等五種成分。檢體先經0.05M KH2PO4溶液 (pH 2.5) 抽取,以高效液相層析儀進行分析。使用之層析管柱為COSMOSIL5C18-AR-II (4.6 mm i.d. × 250 mm) ,移動相為0,05M KH2PO4 (pH2.5) 甲醇 (99: 1 , v/v) ,檢測波長為280nm,並以pyridoxine為內部標準品。五種成分標準品所得五條標準曲線之線性回歸顯示相關係數,R2介於0.9998-1.0000之間,而同日內及異日間試驗之相對標準偏差皆小於2.4%,添加不同濃度之標準品於空白檢體中,其回收率介於93.5-103.3%,相對標準偏差皆小於1.3%, Magnesium ascorbyl phosphate 、Ascorbylglucoside、Kojic acid、Arbutin及Hydroquinone之最低 定量濃度則分別為80.0、20.0、3.0、15.0及10.0μg/mL。 |
英文摘要 | A high performance liquid chromatographic method was developed for simultaneous determination of 5 whitening ingredients: magnesium ascorbyl phosphate, ascorbyl glucoside, kojic acid, arbutin and hydroquinone decomposed from arbutin in cosmetics. Samples were extracted with 0.05 M KH2PO4 buffer solution (pH 2.5) and analyzed using a Cosmosil 5 C18-AR-II column. A mixture of 0.05 M KH2PO4 buffer solution (pH 2.5) and methanol (99:1, v/v) was used as mobile phase. The UV detector was set at 280 nm. Pyridoxine was used as an internal standard. The related coefficients, R2, of regression equations of the 5 standard curves were 0.9998-1.0000. The relative standard deviations of the 5 ingredients for intraday and interday analysis were less than 2.4%. The average recoveries of these 5 ingredients spiked in sample ranged from 93.5% to 103.3%. The relative standard deviations of average recoveries were less than 1.3%. The limits of quantitation in cosmetics were 80.0, 20.0, 3.0, 15.0 and 10.0 mg/mL for magnesium ascorbyl phosphate, ascorbyl glucoside, kojic acid, arbutin and hydroquinone, respectively. |
