MINOR SEED OILS .18. PHYSICOCHEMICAL CHARACTERISTICS AND COMPONENT ACIDS OF 8 SEED OILS

Abstract

Seed oils from Androgaphis paniculata, Calliopsis elegans, Corochorus trilocularis, Crotalaria heyneana, Emblica officinalis, Mangifera indica, Pergularia daemia and Sopubia dulphinifolia have been examined. Of these, the seeds from Androgaphis paniculata, a shrub, Emblica officinalis, a tree, and Mangifera indica, a tree, contain 39.4, 22.4 and 12.0 percent of oil respectively. Pergularia daemia is rich in stearic acid (37.4%). Crotalaria heyneana, Androgaphis paniculata and Calliopsis elegans seed oils are rich in linoleic acid (60.5%, 58.9% and 48.3%) respectively, while seed oils from Corochorus trilocularis and Emblica officinalis contain linolenic acid (3.6% and 5.9%). Seed oils of Pergularia daemia, Corochorus trilocularis and Emblica officinalis having iodine value from 63 to 85 may be useful as nondrying oils.
