Nutrient and bioactive compounds from Neltuma spp. seeds
Abstract
In the search for compounds with nutritional and functional value, seeds
from several Neltuma species were examined for lipid, protein and
phenolic components. Lipid contents ranged between 9.3 - 12.5 g/100 g
(seed DW), and showed MUFA and PUFA predominating largely. Lipids were
also a good source of tocopherols (170 – 603 mg total tocopherols/kg).
Proteins accounted for 14.7 - 35.5 g/100 g seed. Essential amino acids
(EAA) comprised 26.1 – 40.2 % of the total AA content. Based on the
EAA score, proteins from all the species analysed were deficient in
leucine, isoleucine and valine, but could meet requirements for
histidine, threonine, phenylalanine, tyrosine, and lysine. The
qualitative patterns of phenolic compounds were similar each other
(predominance of flavonoids, particularly apigenin derivatives). Keeping
in mind the examined chemical components, Neltuma seeds have potential
value as a source of healthy macronutrients and bioactive compounds.
