摘　　要：采用超声波辅助提取黔产密蒙花黄色素,得到最优的提取条件为:料液比1∶30(g/mL)、超声波时间25 min、超声波功率200 W。此外,密蒙花黄色素稳定性研究表明:密蒙花黄色素在中性及弱酸性的环境中较为稳定,在碱性环境中不能稳定存在;在光照以及50℃以上,密蒙花黄色素易分解;密蒙花黄色素具有一定的抗氧化剂的能力,其抗还原剂的能力较弱。The yellow pigment from Buddleja officinalis Maxim （F P B ） was extracted using ultrasonic-assisted extraction. The optimal extracting conditions was ： material liquid ratio 1 ： 30 （g/ m L ）, ultrasonic time 25 mi n, ultrasonic power 200 W.In addition, the study on stability showed that F P B was more stable in neutral and weak acid environment, and could not be stable in alkaline environment. In the conditions of illumination and 50 ＂ above, FPB was easy to be decomposed.FPB had a certain ability to resistance to oxidizing agent, but was weak to resistance to reducing agent.
