  1. Data are from biodiesel FAME profile obtained by GC-FID of transesterified oils (Jatropha and palm) with alkaline (NaOH) and enzymatic (TL and CA) catalysts. S.D. standard deviation. Listed fatty acid methyl esters (FAME) are: hexadecanoic (16:0), octadecanoic (18:0), cis-9 hexadecenoic (16:1 cis-9), cis-9 octadecenoic (18:1n9c cis-9) and cis-9, 12 octadecadienoic (18:2n6 cis-9, 12). Means with different superscript letters (a, b, c, d) on the same horizontal line are significantly different (LSD test, P < 0.05)
