curcas methyl esters comprises following fatty acids: caproic (2.5%), myristic (9.9%), palmitic (18.5%), palmitoleic (7.8%), steric (9.0%), Oleic (18.8%), elaidic (1.4 %), linoleic (20.2%), linolenic (2.1%), and behenic (2.4%) acids.
The MUFA comprised 55.80% to 56.98% of total fatty acids, and among the MUFA, myristoleic acid ([C.sub.14:1]) comprised 1.25% to 1.49%, palmitoleic acid ([C.sub.16:1]) 5.66% to 5.93%, elaidic acid ([C.sub.18:1]) 1.36% to 1.45%, oleic acid ([C.sub.18:1n-9]) 47.31% to 48.27%, and vaccenic acid ([C.sub.18:1n7]) 0.22% to 0.23% of the total fatty acids.
In this sense, preliminary studies by Barbosa and Oliveira (2010) indicate that the oil obtained from the seeds of this plant contains mainly palmitoleic (1.73% [+ or -] 0.24), oleic (33.26% [+ or -] 1.88) unsaturated fatty acids, (35.32% [+ or -] 1.78), elaidic (4.22% [+ or -] 0.19) and, to a lesser extent, saturated (palmitic) (15.77% [+ or -] 0.25) and stearic (9.49% 0.35) [22].

C16:0 (palmitic) and omega 9 C18:ln9c (oleic) and C18:ln9t (elaidic) ranged between 11%-15%.
The following TFAs were measured and used in the current study: trans-9-hexadecenoic acid (palmitelaidic acid, C16:1n-7t), trans-9-octadecenoic acid (elaidic acid, C18:1n9t), trans-11-octadecenoic acid (vaccenic acid, C18:1n-7t), and trans-9-, trans-12-octadecadienoic acid (linolelaidic acid, C18:2n-6t, 9t) [18, 19].
In most of the in vitro studies available, elaidic acid (9t-18:1) was examined as a representative TFA in PHO [9].

A total of 35 types of fatty acid were detected but octanoic acid, tridecanoic acid, myristoleic acid, pentadecenoic acid, elaidic acid, linoleic acid, a-linolenic acid, docosadienoic acid, nervonic acid, and docosahexaenoic acid were not detected (Table 2).
(2014) [6] who reported only 8.03% of MUFA, very less amount of oleic acid 0.68%, important percentage of elaidic acid (C18:1 w9 trans) (3.16%) and high trans/cis ratio of MUFA (1.27) in the same variety.
