4. Conclusions
Differences in the composition of fatty acid profiles, different
bioactive compounds and antioxidant capacities were observed
for 16 different SI seeds. Important contents of a-linolenic FA
and low x6/x3 ratio were observed for the 16 SI seeds evaluated.
In addition, considerable amounts of tocopherols (c- and d-tocopherols),
phytosterols (b-sitosterol and stigmasterol) and total
phenolic compounds were observed in all SI seed cultivars. No correlations
were found between the different hydrophilic and lipophilic
bioactive compounds and the antioxidant capacity,
suggesting a complex interaction of the different compounds in
the mode of action of the different antioxidants present in the
samples.
SI seed sparks attention as an important and alternative source
of omega-3 and other bioactive compounds. To our knowledge, this
is the first study focused on the valorisation of 16 different cultivars
of SI seeds and based on their phytochemical composition besides
its use as oil source. Thus, current studies of our group are
focused on the effect of ‘roasting’ on the phytochemical
composition.
