| Abstract: | A new flavonol diglycoside, 3,5-dihydroxy-7,4'-dimethoxyflavone 3-O-neohesperidoside (1), together with four known flavonol 3-O-neohesperidosides were isolated from the leaves of Costus spiralis and their structures were elucidated by a combination of spectroscopic methods and chemical reactions. |
