This paper describes the optimization of a method of simultaneous determination of glycerides, free and total glycerol in biodiesel ethyl esters from castor oil by using gas chromatography. Changes were proposed for the methods ASTM D 6584 and EN 14105 in order to determine these by-product contaminants in biodiesel from castor oil. The silylation reaction for this biodiesel was optimized, and 250 lL MSTFA was used. Its accuracy values were between 70% and 120% with RSD <11%. The identification of monoricinolein and diricinolein was made by gas chromatography with mass spectrometry detection (GC-MS). The matrix effect (ME) was investigated and considered low for glycerol, mono-and diolein; it was medium for triolein. The method was robust even when there were variations in the matrix. It was also successfully used for the determination of glycerides, free and total glycerol in samples of biodiesel from castor oil.

“…Castor oil is a viscous, pale yellow non-volatile and non-drying oil with a bland taste containing $90% of the fatty acid ricinoleic acid (Yamamoto et al 2008). The other major fatty acids are linoleic (4.2%), oleic (3.0%), stearic (1%), palmitic (1%) and linolenic acid (0.3%).…”

“…Ricinoleic acid, the major component of castor oil, is an unsaturated omega-9 fatty acid and a hydroxy acid. It is also found in numerous foods and vegetable and seed oils including olive oil, grapeseed oil, and cottonseed oil [23], which are major components of Mediterranean and Western diets. Like castor oil, ricinoleic acid is approved for daily human intake at doses of 0-0.7 mg/kg by the Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives [3].…”

In the process of validating the elevated zero maze, a common test of anxiety-like behavior, in our laboratory, we demonstrated an anxiolytic-like effect of castor oil and its primary component, ricinoleic acid. We tested the effects of vehicle and chlordiazepoxide in male mice in the elevated zero maze following a 30-min pretreatment time. Chlordiazepoxide is a United States Food and Drug Administration-approved drug that was previously shown to exert anxiolytic-like effects in both the elevated zero maze and elevated plus maze. Chlordiazepoxide was administered at doses of 5 or 10 mg/kg. We used 5% polyoxyl 35 castor oil (Kolliphor® EL) and saline as treatment vehicles and found that the effect of chlordiazepoxide on open zone occupancy and open zone entries was blunted when 5% Kolliphor was used as the vehicle. These tests demonstrated that chlordiazepoxide increased open zone occupancy and entries in the elevated zero maze more effectively when saline was used as the treatment vehicle and that Kolliphor dampened the anxiolytic-like effect of chlordiazepoxide when it was used as the treatment vehicle. Notably, 5% Kolliphor alone slightly increased baseline open zone occupancy and entries. Given that Kolliphor is a derivative of castor oil, we next tested the effect of 5% castor oil and 5% ricinoleic acid, which is a major component of castor oil. We found that both castor oil and ricinoleic acid increased open zone occupancy but not entries compared with saline. Altogether, our findings demonstrate that Kolliphor, castor oil, and ricinoleic acid may exert anxiolytic-like effects in male mice in the elevated zero maze. This potential anxiolytic-like effect of castor oil is consistent with its well-established beneficial effects, including anti-inflammatory, antioxidant, antifungal, and pain-relieving properties.
