Fatty acids of kenaf seed oil

Summary Freshly extracted oil from a sample of kenaf seed, var.Cubano, was found to contain an appreciable amount of epoxy acid as glyceride;cis‐12,13‐epoxyoleic acid was isolated. Its identity was confirmed by analysis and by conversion to threo‐12,13‐dihydroxyoleic acid. The remaining fatty acids were esterified, distilled, and identified by the usual procedures. The percentage composition of the fatty acids was estimated from the data as follows: 9‐hexadecenoic 1, palmitic 19, linoleic 41, oleic 30, stearic 2, arachidic (trace), 12,13‐epoxyoleic 5, undetermined 2.
