Amorpha Fruit Pharmacognosy Research

Systematic pharmacognostic study of Amorpha fruticosa L. is carried out by plant morphology, macroscopic morphology, microscopic morphology and chemical constituents,etc. in this thesis.Through all kinds of chromatographic methods such as silica gel, preparative TLC and HPLC etc., 15 monomers have been isolated from the fruits of Amorpha fruticosa L., and 12 monomers including 1 stilbinoid, 9 flavonoids, 1 triterpefite and 1 fatty alcohol, were identified by physico-chemicaland spectral methods. They are 3,5-dihydroxy-4-geranyl-bibenzyl (1), 5,7-dihydro-8-geranyl-flavanone (2), 6a,12a-dehydrodeguelin (3), 6a,12a-dehydro-a-toxicarol (4), tephrosin (5), dehydrosermundone (6), 7,4'-dimethoxyisoflavone (7), 5-hydroxy-7,4'-dimethoxyisoflavone (8), 7,2',4',5-tetromethoxyisoflavone (9), 2-hydroxy-4,4'-dimethoxychalcone (10), - sitosterol (11) and n-triacontanol (12). Among them,compound 6 is a new natural compound, Compound 1 is for the first time isolated in family Leguminosae, compound 8, 10 , 11 , 12 are for the first time isolated in genus Amorpha, and compound 2, 3, 4, 5, 7, 9 are obtained from the fruits of Amorpha fruticosa L. grown in China for the first time.
