Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract Seeds of Pinus koraiensis (sieb, et zucc.), a valuable timber tree species, are used not only for propagation but also as a traditional distinctive flavour in China. The 1,000 seed weight was about 570g, of which the kernel, edible part, made up about 31%. The content of oil extracted from the kernel with petroleum ether was 68.0% and with ether 73.4% The appetizing oil, specific gravity D2020 0.9218~0.9222, refractive index N20D, 1.4768~1.4774, iodine number 145.5~149.5, acid number 0.50~0.62, was a yellowish, viscouse liquid at normal temperature. It was found by GLC that there existed at least eleven fatty acids in the oil, of which eight were identified in our investigation as myristic acid, 0.35%; palmitic acid, 4.28%; stearic acid, 2.11%; oleic acid, 25.18%; n-nonadecylic acid, 2.62%; linoleic acid, 42.22%) 5, 9, 12-octadecatrienoic acid, 17.57% and linolenic acid, 1.81%. The content of the unsaturated fatty acids amounted to more than 85% of the total fatty acids. The above suggests that the seed of Pinus koraiensis is well worth exploiting for its potential nutritious value.
