Hydnocarpyl acetate (III), chaulmoogryl acetate (III′), isohydnocarpyl acetate (VIII), and isochaulmoogryl acetate (VIII′) derived from the componental fatty acids of hydnocarpus oil, hydnocarpic acid (I) and chaulmoogric acid (I′), were each oxidized with potassium permanganate in acetic acid and 4 kinds of ω-hydroxyketonic acids were obtained; 4-oxo-15-hydroxypentadecanoic acid (V), 4-oxo-17-hydroxyheptadecanoid acid (V′), 5-oxo-16-hydroxyhexadecanoic acid (X), and 5-oxo-18-hydroxyoctadecanoic acid (X′). The melting point of these acids and their derivatives are listed in Table I.
