1. The oils of four representatives of the family Umbelliferae have been investigated. Their physical and chemical indices have been characterized, and their fatty-acid and glyceride compositions have been determined. In all the oils the acid present in largest amount is petroselinic acid (30–45%), which may be considered as a chemicophysiological-classification characteristic of plants of the family Umbelliferae.
2. Unusual acids — octadec-7-enoic (2.8–6.9%) and octadec-8-enoic (2.7–3.1%) — have been found in the oils ofAthamanta macrophylla,Archangelica tschimganica, andBunium hissaricum. Octadec-8-enoic acid had never previously been found in natural oils.
