Identification of L-Inositol and Scyllitol and Their Distribution in Various Organs in Chrysanthemum

Abstract

  Two unidentified soluble carbohydrates were isolated from chrysanthemum (Dendranthema×grandiflorum (Ramat.) Kitamura) leaves using HPLC. The compounds were identified as 1 L-chiro-inositol, called L-inositol (1) and scyllo-inositol, called scyllitol (2) from the results of ¹H-NMR, ¹³C-NMR, and CI-MS spectra. L-Inositol and scyllitol were distributed in four cultivars tested. L-Inositol concentration of petals gradually decreased during the flower bud development, but the L-inositol content increased by about 7 times. Scyllitol was detected only at an early stage of flower bud.
