Propolis is a valuable natural substance obtained by honey bees after being collected from the bark, resin of trees, plant leaves and mixed with their saliva, and has been widely used for various biological activities. The properties of propolis can vary widely by botanical origin, location of the hives and colony population. It is thought that the color of propolis is one of the main factors determining its acceptability and originates from the flower markers, pollen and nectar of some plants and is directly related to its chemical content. It is important to compare and standardize the colors, chemical content and biological activities of propolis in our country, which has a rich endemic plant diversity. Thus, in this study, the color indexes of 39 propolis samples from different locations in Turkiye were determined by Lovibond Tintometer, for the first time. The color index, total phenolic content, cytotoxic and antioxidant activities relationship of propolis and two commercial propolis samples were also investigated by HCA and PCA. Turkish propolis, which is defined by its color indices, chemical contents and many different activity potentials, such as antioxidant, antiviral and cytotoxic activity, will find use in many fields from medicine to cosmetics with this study.
蜂胶是蜜蜂从树皮、树脂、植物叶子中采集并与它们的唾液混合后获得的一种珍贵天然物质，已被广泛用于各种生物活性。蜂胶的特性会因植物来源、蜂巢位置和蜂群数量而有很大差异。人们认为，蜂胶的颜色是决定其可接受性的主要因素之一，它源于某些植物的花标记、花粉和花蜜，并且与其化学含量直接相关。在我国，本土植物种类丰富多样，因此比较和规范蜂胶的颜色、化学含量及生物活性非常重要。因此，在本研究中，首次使用罗维朋比色计测定了来自土耳其不同地点的39个蜂胶样品的颜色指标。还通过聚类分析（HCA）和主成分分析（PCA）研究了蜂胶及两个商业蜂胶样品的颜色指标、总酚含量、细胞毒性和抗氧化活性之间的关系。本研究中定义的具有颜色指标、化学含量以及多种不同活性潜力（如抗氧化、抗病毒和细胞毒性活性）的土耳其蜂胶，将在从医学到化妆品的许多领域得到应用。
