Conclusions

On the basis of the rates of their acid hydrolysis, their optical activities, and their IR spectra, it has been established that the glycosides ofAesculus hippocastanum L. are (SK-1) 3-α-L-arabofuranosyloxy-5,7,4′-trihydroxyflavone, (SK-2) 3-α-L-rhamnofuranosyloxy-5,7,4′-trihydroxyflavone, (SK-3) 3-α-L-arabofuranosyloxy-5,7,3′,4′-tetrahydroxyflavone, and (SK-4) 3-α-L-rhamnofuranosyloxy-5,7,3′,4′-tetrahydroxyflavone.

The glycoside SK-3 is identical with avicularin isolated from the leaves ofPsidium quajava [5]. The complete structures of the other three glycosides have been established for the first time.
