摘　　要：运用显色反应、紫外吸收光谱法对细穗柽柳中的黄酮类化合物进行鉴定 ,基本确定了细穗柽柳中含有黄酮类化合物 ,并分析了可能影响细穗柽柳中黄酮类化合物提取的各种因素。在对水提法、醇提法和碱提法进行比较研究的基础上 。Flavonoid is one of the primary living substances in most plants and is extensively distributed in plants. Many new kinds of flavonoids and their physiological actions are continuously found with the improvement of research technology and methods. Therefore, flavonoids are extensively favored because of their outstanding physiological actions in many fields, such as pharmacy and food processing. In this paper, the flavonoids in Tamarix leptostachys are appraised and demonstrated by using color action and ultraviolet absorbency. The results show that there are flavonoids in Tamarix leptostachys. The factors affecting the extraction of flavonoids from Tamarix leptostachys are analyzed. Three extracting methods are compared by taking water, ethanol and alkali as the solvents respectively, and the optimum extracting process is testified by normal experiment. The study area (42°51′N, 89°11′E, -86 m a.s.l.) is located in Turpan Desert Botanical Garden, Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences. The soil here is sandy loam, the extremely maximum and minimum temperatures are 47.6 ℃ and 28.0 ℃ respectively, and it belongs to the extremely arid desert climate. The community of Haloxylon persicum growing in the study area forms by introducing Haloxylon persicum from Ganjiahu Nature Reserve of Haloxylon ammodendron in Jinghe County, Xinjiang Uygur Autonomous Region in 1976. Currently, the plant height varies in a range of 5～7 m, and the average crown extent of Haloxylon persicum is 4.0 m×4.0 m.
