Abstract: | An n-hexane extract of fresh, mature leaves of Ludwigia adscendens, containing a thin layer of epicuticular waxes, has been analysed for the first time by TLC, IR and GC using standard hydrocarbons. The leaves contained 22 identified long chain (C15-C36) n-alkanes, accounting for 74.27% of the hydrocarbons present, and an unknown number of unidentified branched chain alkanes. The predominant n-alkane was C25 (11.02%), whilst C18 (7.62%), C20 (6.14%), C29 (5.36%) and C27 (5.29%) n-alkanes were moderately abundant: the C35 homologue was present only in minor amounts (0.22%). |
