Among the 13 types of propolis classified in Brazil according to their physicochemical properties, green propolis and brown propolis are the most commonly found and used. In this work, a comparison of the physicochemical properties of green and brown propolis produced in Minas Gerais, Brazil was performed according to the methodology established by the Brazilian legislation. And, the content of 9 bioactive compounds in the samples was determined by RP-HPLC. GrProp showed a higher content of pinocembrin, artepillin C and baccharin, and a higher quantity of total flavonoids, in comparison with BrwProp. The mechanical mass content in both types of propolis was above the limit established by legislation. However, the other physicochemical parameters were within the limits. The chemical composition, especially the flavonoid content and the free radical (DPPH) scavenger property confer to both types of propolis a promising pharmacological activity.
在巴西根据理化性质分类的 13 种蜂胶中，绿蜂胶和棕蜂胶是最常见和使用最多的。在这项工作中，根据巴西法规规定的方法，对产自巴西米纳斯吉拉斯州的绿蜂胶和棕蜂胶的理化性质进行了比较，并通过反相高效液相色谱法（RP-HPLC）测定了样品中 9 种生物活性化合物的含量。与 BrwProp 相比，GrProp 含有更高的 pinocembrin、artepillin C 和 baccharin，以及更高数量的总黄酮。两种类型的蜂胶的机械质量含量都超过了法规规定的限值。然而，其他理化参数都在限值范围内。化学成分，特别是类黄酮含量和自由基（DPPH）清除能力，使这两种类型的蜂胶具有有前途的药理学活性。
