Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract Tucum (Astrocaryum vulgare Mart) palm pulp oil was fractionated by acetone crystallization to yield a solid fat (stearin) and a free flowing oil (olein). Yield of solid fat was 14.3% and that of oil 85.7%. As in whole tucum oil, the major fatty acids in the fractions were palmitic and oleic (O), with smaller amounts of stearic (S), linoleic and arachidic acids. Fractionation led to a randomization of palmitic and oleic acid in olein and stearin triglycerides. Relative to whole tucum oil there was an increase in the high m.p. triglycerides 3S and 2S:O and a lowering of S:2O in the stearin fraction, while in the olein there was a lowering of 3S and 2S:O and an increase in S:2O. Tabulated data show the fatty acid composition and characteristics, 2-monoglycerides and triglyceride composition of whole tucum oil, stearin and olein fractions. [From En summ.]
