Twenty-five samples of propolis were collected from seven different regions in northern Argentina; ethanolic extracts of propolis were prepared from all samples, and the respective samples were examined for UV absorption spectra, RPHPTLC, RPHPLC, antimicrobial activity, antiradical activity, and total phenolic content. It was found that 16 of the 25 samples showed a phenolic profile similar to that found in samples from southern Brazil and corresponding to poplar-based propolis and that the rest of the samples showed a different profile and higher antimicrobial and antiradical activities.
从阿根廷北部七个不同地区采集了25个蜂胶样本；从所有样本中制备了蜂胶乙醇提取物，并对各个样本进行了紫外吸收光谱、反相高效制备薄层层析、反相高效液相色谱、抗菌活性、抗自由基活性和总酚含量检测。结果发现，25个样本中有16个样本的酚类特征与巴西南部样本相似，对应于杨树型蜂胶，其余样本则呈现出不同的特征，且具有更高的抗菌和抗自由基活性。
