The yield, isolation and properties of starch and its fractions from dropwort ( Filipendula vulgaris ) have been investigated. The starch content of tubers ranged from 9.5 to 14.0%. The size of starch granules was 2 to 12 μm. Fertilization seems to increase their size. The granules stained relatively faintly. The polarization cross was strong and centric. Thr amylose content of starch was 27 to 32%, and the molecular weight, corresponding to 50% of the starch components. was about 10 6 . Gelatinization properties were fof wheat type.
