蜂胶与杨树芽提取物成分的比较研究

采用高效液相色谱-二极管阵列检测器-多极质谱联用法,分析了陕西、河南、湖北、河北、辽宁、浙江、山东、甘肃和贵州等地的30个蜂胶样品以及2个不同产地杨树芽乙醇提取物的化学成分。结果表明:30个蜂胶样品与杨树芽乙醇提取物的成分十分相似,生松素、珂因和高良姜素是存在于蜂胶和杨树芽中的主要黄酮类化合物。另外,中国蜂胶和杨树芽提取物中含有咖啡酸苯乙酯、咖啡酸苯甲酯、苯甲基-p-香豆酸、2-甲基-2-丁烯基-阿魏酸、3-丙酰基-短叶生松素、2-甲基-2-丁烯基-p-香豆酸、肉桂酰咖啡酸、反式-阿魏酸和顺式-阿魏酸等化合物。

A Comparative Study on Chemical Compositions of Chinese Propolis and Poplar Resin

-Chemical compositions of the ethanolic extracts of 30 propolis samples from Shaanxi, Henna, Hubei, Hebei, Liaoning, Zhejiang Shandong and Gansu provinces and two poplar resin samples were determined using reversed-phase high-performance liquid chromatography (RPHPLC)-mass spectrometry with photodiode array detector. The results showed that chemical compositions of the tested propolis samples were the same and pinocembrin, chrysin and galangin were the dominant flavonoids in the tested propolis and poplar resins. In addition, phenethyl caffeate, benzyl caffeate, benzyl p-coumarate, 2-methyl-2-butenyl ferulate, piobanksin 3-propanoate, 2-methyl-2-butenyl p-coumarate, cinnamyl caffeate, trans-ferulic acid and 2-methyl-2-butenyl ferulate were also identified both in chinese propolis and poplar resins.
