Propolis is a complex honeybee product with resinous aspect, containing plant exudates and beeswax. Their color, texture, and chemical composition vary, depending on the location of the hives and local flora. The most studied Brazilian propolis is the green (alecrim-do-campo) type, which contains mainly prenylated phenylpropanoids and caffeoylquinic acids. Other types of propolis are produced in Brazil, some with red color, others brown, grey, or black. The aim of the present work was to determine the chemical profiles of alcohol and chloroform extracts of eight samples of propolis, corresponding to six Brazilian regions. Methanol and chloroform extracts were obtained and analyzed by HPLC/DAD/ESI/MS and GC/MS. Two chemical profiles were recognized among the samples analyzed: (1) black Brazilian propolis, characterized chiefly by flavanones and glycosyl flavones, stemming from Picos (Piauí state) and Pirenópolis (Goiás state); (2) green Brazilian propolis, characterized by prenylated phenylpropanoids and caffeoylquinic acids, stemming from Cabo Verde (Bahia state), Lavras and Mira Bela (Minas Gerais state), Pariquera-Açu and Bauru (São Paulo state), and Ponta Grossa (Paraná state). The present work represents the first report of prenylated flavonoids in Brazilian propolis and schaftoside (apigenin-8-C-glucosyl-6-C-arabinose) in green propolis.
蜂胶是一种具有树脂状外观的复杂的蜜蜂产品，含有植物渗出物和蜂蜡。其颜色、质地和化学成分因蜂巢的位置和当地的植物群而异。研究最多的巴西蜂胶是绿色（alecrim-do-campo）型，主要含有prenylated phenylpropanoids 和 caffeoylquinic acids。巴西还生产其他类型的蜂胶，有些是红色的，有些是棕色、灰色或黑色的。本工作的目的是确定来自巴西六个地区的八种蜂胶样品的醇提物和氯仿提取物的化学特征。用 HPLC/DAD/ESI/MS 和 GC/MS 分析甲醇和氯仿提取物。在所分析的样品中识别出两种化学特征：（1）黑色巴西蜂胶，主要特征为 flavanones 和 glycosyl flavones，源自皮科斯（皮奥伊州）和皮里涅罗波利斯（戈亚斯州）；（2）绿色巴西蜂胶，主要特征为 prenylated phenylpropanoids 和 caffeoylquinic acids，源自卡博弗里乌（巴伊亚州）、拉夫拉斯和米拉贝拉（米纳斯吉拉斯州）、帕里夸拉-阿苏和包鲁（圣保罗州）以及蓬塔格罗萨（巴拉那州）。本工作首次报道了巴西蜂胶中的 prenylated flavonoids 和绿蜂胶中的 schaftoside（apigenin-8-C-glucosyl-6-C-arabinose）。
