The Chemical Constituents Study in the Root of Astragalus membranceus

Abstract:

To sdudy the chemical constituents in root of Astragalus membranceus. Compounds were separated and purified by polyamide column and silica gel column. seven compounds (I--VII) were obtained from the root of Astragalus membranceus:Sucarose (I), β-Sitosterol (II), Formnonetin (7-hydroxy-4-methoxyiso-flavove III), Calycosin (7,3-dihydroxy-4-methoxyisoflavove IV). Their structures were identified On the base melting point, value of Rf, spectral methods. Compounds III and IV are first isolated from the root of Astragalus membranceus. Compounds I,II,V, VI and VII are Compounds are isolated from the root of Astragalus membranceus.
