The fatty acid composition of the seed oil of Curupira tejiemis was analysed by capillary GC of their methyl esters. The gaschromatographic assignments were ensured by corresponding mass spectra. The oil is composed to more than 62 O/n of very long chain fatty acids (> C18). Erucic acid is found to be the main component (35%). The position of the double bonds of the rnonounsaturated fatty acids (MUFAME) was verified after derivatization with dimethyl disulfide and subsequent GUMS analysis. AU identified MUFAME belong to the (n-%)type. The UV-spectroscopical data show that approx. 1.2% conjugated acetylenic fatty acids occur in the oil. Furthermore IKand NMRspectroscopical investigations and the basic analyses of the seed were carried out.

## Abstract The evidence for beneficial effects of very long chain (VLC) n‐3 polyunsaturated fatty acids (PUFA) on cardiovascular disease (CVD) is strong because it is based on the results of adequately powered intervention trials with disease endpoints. This contrasts with the evidence for a detri
