Fatty Acids in Pollen of Some Coniferous Species.

Fatty acids in pollen of five coniferous species were isolated and analyzed by gas-liquid chromatography. It was found that 0.76 to 0.89 percent of the dry weight of pollen was fatty acid in three species of Pseudotsuga and 1.25 to 1.33 percent in two species of Pinus. Major components in Pseudotsuga were oleic, palmitic, and linoleic acids, whereas in Pinus they were linolenic, oleic, palmitic, and stearic acids.
