Structural analysis of 1l-chiro-inositol diester from Taraxacum udum

1l-1,5-Di-O-p-hydroxyphenylacetyl-chiro-inositol was isolated from the leaves of Taraxacum udum, along with seven other secondary metabolites. Identification of the inositol derivative, based on extensive spectroscopic analyses (1H, 13C and 2D NMR) in two solvents, allowed the correction of previously published data and conformational studies. This is the second report on the presence of inositol esters with p-hydroxyphenylacetic acid in plants.
