The Sendan seeds were collected in Tosa province at winter, and were extracted with light petroleum ether. The yield of oil was 4.7% and it had following constants : d254 0.9265, n25D 1.4796, A.V. 8.3, S.V. 223.4 and I.V. 80.6.
The oil was saponified with usual method, and mixed acid was obtained with 70.0% yield, which had following constants : d304 0.9369, n30D 1.4743, N.V. 213.6 and I.V. 96.4.
Separation was made byPb salt-alcohol method into solid and liquid acids, which were esterified with methanol and hydrochloric acid, and were fractionated in vacuum. Each fraction was examined for its component, and by means of gas chromatography it was characterised for the presence of caprylic, capric, lauric, myristic, palmitic and stearic acid as saturated fatty acids, and oleic and linoleic acid as unsaturated acids.
