Objective : To study the chemical composition of the root of Astragalus membranaceus in Helan Mountain. Methods: The chromatographic method and spectral method and related physical constants were used to compare the chemical composition and structure identification. RESULTS: Six quinones and four terpenoids were obtained: stigmas 3,6 2 ketones (1), 5α, 8α dioxo (2 2E, 24R) ergoside 6, 2 emodin 3β Alcohols (2), Sophoran 3β, 6αdiols (3), Carboxylic (4), β-sitosterol (5), Soybean alcohol (6), Chrysophanol (7), Emodin (8), Emodin Methyl ether (9) and aloe-emodin (10). Conclusion : Compounds 1～3 and 7～10 were found for the first time in the genus Astragalus.
