Cinnamate derivatives of fructo-oligosaccharides from Lindelofia stylosa.
Phytochemical investigation on the whole plants of Lindelofia stylosa (Kar. and Kir.) has led to the isolation of eight fructo-oligosaccharide cinnamate esters 1-8. Six new compounds 1, 2, and 5-8 were isolated from the butanol extract of the plant. Compounds 1-4 belong to sucrose derivatives, while compounds 5-6 and 7-8 belong to 1-kestose- and nystose-type oligosaccharides, respectively. The fructo-oligosaccharides have been obtained from L. stylosa for the first time.
