      R. MADRIGAL, C. SMITH

      Lipids 17, 650-655 (1982). For preparative separation silica plates were used with hexane - ether 6:4. For separation of hydrogenated oils into their various components, multiple development (4 or 5x) TLC was carried out with ether - benzene 1:99 followed by ether - benzene 3:97. Analytical TLC components were visualized by charring with sulfuric acid-dichromate or with iodine vapors. reparative TLC: bands were located by spraying with ethanolic dichlorofluorescein, followed by viewing under UV. The components of the seed oil of trewia nudiflora and mallotus phillipinensis were chromatographed and compared.
