Flax bast tissue was sequentially extracted using hexane, propanol, methano
l and water as solvents and extracts were analyzed using reverse phase HPLC
and C-13 NMR. Results indicated a large variety of aromatic constituents i
ncluding flavonoids and hydroxy-methoxy cinnamic acids linked to oligosacch
arides and hydroxy acids through glycosidic linkages. The extracts inhibite
d cellulase and pectinase activities and can thus influence retting.
