摘　　要：从九里香(Murrayaexotica L.)叶中分离得到三个甲氧基黄酮类化合物:5,7,3′,4′-四甲氧基黄酮(化合物1)、5,7,3′,4′,5′-五甲氧基黄酮(化合物2)和5,6,7,3′,4′,5′-六甲氧基黄酮(化合物3).应用1D和2D NMR(包括1H-1HCOSY、HMQC和HMBC)对这三种化合物的结构进行了分析,确认了三个化合物中甲氧基的连接位置,并对1H和13C化学位移进行了归属.Three methoxyflavone compounds. 5, 7, 3′, 4-′tetramethoxyflavone （compound 1）, 5, 7, 3′, 4′, 5′-pentamethoxyflavone （compound 2） and 5, 6, 7, 3′, 4′, 5′- hexamethoxyflavone （compound 3） were separated from the leaves of Murraya exotica L, among which compound 2 was reported for the first time. ^1H and ^13C NMR spectra （including ^1H-^1H COSY, HMQC and HMBC） of the compounds were acquired and assigned. The structures of the compounds were elucidated. The position of the methoxyl group in each of the compounds was determined.
