The Foliar Fatty Acids In The Weed, Ludwigia Adscendens L.

A.Barik, T.C.Banerjee

The foliar fatty acid fractions and their relative concentrations in the weed, Ludwigia adscendens L. were determined by TLC and GC-FID analyses of methyl esters in the n-hexane extract of mature leaves. The lipids content was 5.74% of the mg/g dry leaf tissue. Fatty acids identified were palmetic acid (C16), oleic acid (C18) and stearic acid (C18) having 65.57, 4.85 and 10.79% concentrations, respectively. The identity of the peaks 1, 2 and 4 in the chromatogram could not be obtained, but these indicated 6.88, 6.09 and 5.82% concentrations in the mature weed leaf, respectively.
