摘要
本研究的目的是测定泡茶中多酚的含量。样本分别采用三个样本。采用70%乙醇浸出法提取包装茶中的多酚类化合物。定性试验采用FeCl3试剂，定量试验采用福林试剂紫外-可见分光光度法测定多酚含量。本研究以没食子酸为比较剂。定性检测结果均为含多酚包装茶样品。样品A、B、C的多酚含量分别为0.538;0554;和0470年;% b / b。
ANALISIS POLIFENOL EKSTRAK TEH TUBRUK KEMASAN MENGGUNAKAN SPEKTROFOTOMETRI UV-VIS
The purpose of this research is determine the polyphenol content of brewed tea. Sample were used three sample. Polyphenol compounds of packaged tea were extracted using percolation method with ethanol 70%. Qualitative test were used using FeCl3 reagent and quantitative test polyphenol content were determined using UV-Vis spectrophotometry method with Folin Ciocalteau reagent. Galic acid was used as comparator in this research. The result of qualitative test is all sample of packaged tea containing polyphenol. Polyphenol content sample A, B, and C, with peercolation method were respectively 0,538; 0,554; and 0,470; %b/b.
