Abstract The glycerides of stillingia oil have been studied by resolution into a series of fractions by crystallization from acetone. Deca‐2: 4‐dienoic acid, which forms about 8% (mol.) of the total acids of the oil, is shown to occur almost exclusively as monodecadienoic di‐C 18 ‐polyethenoid glycerides with the short‐chain acyl group in the β‐or symmetrical position. The chief constituents of the oil are linoleodilinolenins, decadienolinoleolinolenins and decadieno‐dilinolenins, with lesser proportions of saturated‐linoleolinolenins, saturated‐dilinolenins, oleolinoleolinolenins and oleodilinolenins. Owing to the presence of the decadienoic acid (8%) with linolenic acid (51%) and linoleic acid (22%), the total proportion of tripolyethenoid glycerides (95%) in the oil is greater than in linseed oil and comparable with that in conophor oil. This accounts for the relative behaviour of stillingia oil and linseed oil as drying oils in paint films.
