Abstract
Results of an investigation made in 1929 on the oil expressed from combined samples of stillingia seed from California, Florida and Texas are given, along with those recently obtained from an imported sample of stillingia oil. The American oil gave an iodine number of 176.1, a saponification value of 211.7, and a thiocyanogen value of 102.7, and was found to contain the following percentages of acids: Oleic 7.7, linoleic 56.3, linolenic 24.6, palmitic 4.42, stearic 1.43 and arachidic acid 0.34. The sample of Chinese oil gave an iodine number of 169.0, a saponification value of 206.2, and a thiocyanogen value of 100.7, and was found to contain the following percentages of acids: Oleic 10.4, linoleic 49.9, linolenic 25.4, palmitic 5.89, stearic 2.64 and arachidic acid 0.14. From the characteristics and composition of these samples, it would appear that stillingia is suitable for use in the manufacture of paints and varnishes.
