Phytochemical studies of sophora exigua craib root

Abstract

By means of chromatographic and crystallization techniques from the roots of Sophora exigua Craib led to the isolation of a novel flavanone, 5, 7, 2' , 4' , 6'-pentahydroxy-8-lavandulylflavanone (68), and 3 known flavanones, exiguaflavanone B (65), exiguaflavanone A (66), kushenol A (67). The identification and structure elucidation of isolated compounds were executed by the physical and chemical properties and spectroscopic data. The bioactivity assay found that compounds 66 was a moderately strong inhibitor of Ca2+ ATPase.
