Propolis is a bee product with a wide range of biological activities and its chemical compounds depend highly on the type of plant accessible to the bees. The Changbai Mountains are a major mountain range in Northeast China and are one of the major bee product-producing areas in China. In this study, we evaluated the total phenolic acids and flavonoid contents as well as the antioxidant activity of propolis sampled from the Changbai Mountains area (CBM). We identified the major compounds and qualified their contents by HPLC-ESI/MS and HPLC-UV, and found that the content of -coumaric acid and an unknown peak (CBE) in CBM propolis was higher than in propolis from other parts of China. The unknown compound CBE was isolated, purified, and identified as benzyl -coumarate by MS and NMR. Possible plant sources of CBM propolis are dode and Carr, which widely distributed in the Changbai Mountains area. CBM propolis is a new propolis type, that could be an excellent raw material for health foods and pharmaceuticals.
蜂胶是一种具有广泛生物活性的蜜蜂产品，其化学成分高度取决于蜜蜂可获取的植物类型。长白山是中国东北地区的主要山脉，也是中国主要的蜂产品产区之一。在这项研究中，我们评估了来自长白山地区（CBM）的蜂胶的总酚酸和类黄酮含量以及抗氧化活性。我们通过 HPLC-ESI/MS 和 HPLC-UV 鉴定了主要化合物及其含量，并发现 CBM 蜂胶中的 -香豆酸和未知峰（CBE）的含量高于中国其他地区的蜂胶。未知化合物 CBE 通过 MS 和 NMR 被分离、纯化并鉴定为苯甲酸肉桂酯。CBM 蜂胶的可能植物来源是 dode 和 Carr，它们广泛分布在长白山地区。CBM 蜂胶是一种新型蜂胶，可作为保健食品和药品的优质原料。
