Crepis rubra

Constit. of Dimorphotheca sinuata and Crepis rubra seed oils, also obt. from Linoleic acid. Mp 1°. 

For obvious reasons, studies on lipid content during seed or fruit development have concentrated on commercially important oil-rich seeds. Two excellent publications have reviewed much of the available data (Appelqvist, 1975 Hitchcock and Nichols, 1971). Plants which have been studied include the seeds of maize, Crambe abyssinica, rape, castor bean, soybean, flax, safflower, sunflower, white mustard, Crepis rubra, and Veronica anthelmin-tica and the fruits of the oil palm. Fat accumulation in oil-rich seeds generally occurs in three distinct stages. First, there is an interval of from 10 to 30 days after pollination when little fat accumulation takes place. This is followed by a stage of 2-5 weeks when a rapid increase in total lipid is observed. During the final stage, little change in lipid content occurs.
