Crambe seed (Crambe abyssinica) is an excellent, recently established source of high-erucic acid oil. Erucic acid has a number of important and potential applications. To develop this potential, a rapid bench-scale method was desired whereby purified erucic acid in up to several 100-g quantities could be produced from crambe seed. Using the method developed, oil was expressed from dried, intact seed; clarified, degummed, and bleached; and saponified and acidified to obtain the free fatty acids. Analysis by inductively coupled plasma of the free fatty acids showed negligible levels of phosphorus and most minerals. Erucic acid was twice crystallized from 95% ethanol at −14°C, resulting in a purity of 87.1%. This process yielded 365 g erucic acid crystals per kg bleached oil. Nuclear magnetic resonance analysis showed that the prepared erucic acid had an excellent pattern of correlation with a commercial standard. The time needed to convert 1 kg of crambe seed to erucic acid is about 48 h. Crystal filtration and drying stages under the current process conditions require 30% of the overall time. The method is suitable for producing adequate quantities of erucic acid for use in studies of its bench-scale conversion. There is obviously, still, a fruitful field of work to be explored in the formalization of refining procedures for crambe oil. It seems that crambe is destined to continue expansion into the higherucic acid oil markets.Paper no. J9058 in JAOCS 76, 801-809 (July 1999).

“…The current major industrial source of erucic acid is high-erucic acid rapeseed oil [2][3][4]. In recent years, Crambe abyssinica is becoming more and more interesting as an alternative industrial crop [5][6][7] since it shows high-erucic acid content (52% -59%) in its seed oil and also wide climatic and agronomic adaptation and does not cross with the double-low canola. Just recently, the erucic acid content in Crambe seed oil was increased to over 70% [8].…”

In the present study correlation, regression and path analyses were carried out to decide correlations among the agronomic traits and their contributions to seed yield per plant in Crambe abyssinica. Partial correlation analysis indicated that plant height (X 1 ) was significantly correlated with branching height and the number of first branches (P < 0.01); Branching height (X 2 ) was significantly correlated with pod number of primary inflorescence (P < 0.01) and number of secondary branches (P < 0.05) and negatively correlated with number of first branches (P < 0.01); Number of first branches (X 3 ) was significantly correlated with number of secondary branches (P < 0.01), pod number per plant and 1000-grain weight (P < 0.05); Number of secondary branches (X 4 ) was significantly correlated with seed yield per plant (P < 0.05); Pod number per plant (X 7 ) was significantly correlated with seed yield per plant (P < 0.01) and negatively correlated with 1000-grain weight (P < 0.01); 1000-grain weight (X 8 ) was significantly correlated with seed yield per plant (P < 0.01). Stepwise regression and path analyses indicated that only pod number per plant and 1000-grain weight contributed significantly to seed yield per plant at P < 0.01 and P < 0.05, respectively. The regression formula for contributions of pod number per plant (X 7 ) and 1000-grain weight (X 8 ) to seed yield per plant (Y) is Y = 0.006 X 7 + 1.222 X 8 − 7.191. The path coefficient of pod number per plant to seed yield per plant was 0.967 and that of 1000-grain weight was 0.194. The determination coefficient of pod number per plant and 1000-grain weight to seed yield per plant was 0.983 and the determination coefficient of other agronomic traits was 0.130. Coefficient of variance indicated that the length of primary inflorescence showed the greatest variation, followed by seed yield per plant, pod number per plant, number of secondary branches, branching height, pod number of primary inflorescence, number of first branches, seed yield per plot, 1000-grain weight and plant height. It was suggested that seed yield per plant in Crambe might be improved by increasing the pod number per plant through selection or cultivation, but the negative correlation between pod number per plant and 1000-grain weight also needs to be considered.

“…The oil content of the hulled Crambe seed varied the most; this was probably related to the variation in thickness of the fruit coat (Francis and Campbell, 2003). C. abyssinica, having a significant amount of oil (32-36%) with a higherucic acid content (52-59%), along with its wide climatic and agronomic adaptation, is a promising alternative crop (Lazzeri et al, 1994;Mikolajczak et al, 1961). All collected Crambe species were germinated under the Çukurova conditions, in southern Turkey, but only C. orientalis (Kahramanmaraş) succeeded in reaching a full grown state while other Crambe sp.…”

ABSTRACT. Crambe sp. is an oilseed crop from the Brassicae family and native to the Mediterranean region. It can be converted into a number of industrial and energy uses. Crambe oil is used in introducing in stain, primers, plastic and solid wax, cosmetic and engine portions in the form of nylon-13.13 exclude carburetor as eco-friendly. All these properties make it interesting. This study is the first report on yield, cultivation procedure, and quality characteristics of Crambe sp. cultivated in Turkey. Native Crambe seeds, collected from eight different locations in Turkey, were cultivated under Çukurova conditions in Mediterranean region. Two Crambe species, Crambe orientalis and Crambe tataria, determined at the locations were studied, and some morphological characteristics and oil compositions were sown from cultivars and native forms. Fatty acid composition of seeds was examined with GC and GC/MS. In native populations, high seed oil contents were obtained from C. tataria (AnkaraFaculty of Science and Letters) and C. tataria (Kahramanmaraş-Elbistan), as 45.62 and 45.50%, respectively. The highest erucic acid content (49.0 %) was found in C. tataria (Ankara-Bilkent). In Çukurova conditions, despite cultivated all collected species, just C. orientalis was bloom among this species, and so that seed yield (472.77 kg/ha) oil rate (% 27.43) and erucic acid (41.0 %) could determine just this species.
