| Abstract: | In the report, column chromatography with silica gel and Sephadex LH -20, the recrystallization method were used to isolate and purify the chemical constituents of Hedyotis coryrnbosa, and the structures of the chemical constituents were analyzed based on the physical properties and spectroscopic data. The results indica- ted that five known Flavones and other two compounds were obtained. Their structures were identified as 5,6,7, 4＇ - tetramethoxyflavone（ I ）, 7 - hydroxy -5,6,4＇ - trimethoxyflavone （ II ）, 3＇,4＇ ,5,6,7 - pentamethoxyfla- vone（ III ）, 5,7,4＇ - trihydroxy - 6 - methoxyflavone （ IV ）, 5,4＇ - dihydroxy - 6,7 - dimethoxyflavone （ V ）, α- Amyrin （VI）, α-sitosterol（ IV）, respectively, all of which were isolated from the plant for the first time. |
