Abstract
The lipids of Tropaeolum speciosum (T speciosum) are a rich source of natur ally occurring nervonic acid (24: 1 n-9). We report that adding a T. specio sum oil supplement to a semi-purified diet significantly increased the amou nt of 24: 1 n-9 in liver and heart, but not brain, sphingomyelin (SM) of yo ung rats. The bioavailability of 24: 1 n-9 from the lipids of T. speciosum was similar to that of 24: 1 n-9 ethyl ester in this rat bioassay. (C) 2001 Elsevier Science Inc. All rights reserved.
