- Abstract
In this study, the contents of total and individual phytosterols in sprouts made from seeds of seven canola ( Brassica napus L.) lines (Acropolis, Banjo, Jetton, KS-7740, KSM3-1-124, Mussette and Virginia), grown at three locations in Virginia (Orange, Petersburg and Suffolk), were determined. Canola sprouts contained, on an average, 36.3 g sterols in 100 g of unsaponifiable matter (UNSAP), 10.7 mg sterols in 1 g of oil and 2.4 mg sterols in 1 g of dry sprouts. The contents of individual phytosterols (μg per g of oil) in canola sprouts were 1,162 brassicasterol, 3,799 campesterol, 34 stigmasterol, 5,359 β-sitosterol, 201 Δ-avenasterol and 97 Δ-stigmastenol. Canola lines had significant effects on the contents of oil, brassicasterol and campesterol. Locations had significant effects on the oil, UNSAP, total sterols, brassicasterol, stigmasterol and β-sitosterol. The oil content in canola sprouts was positively correlated with total sterols and Δ-avenasterol, whereas oil content was negatively correlated with brassicasterol content. In general, the contents of campesterol and β-sitosterol increased with an increase in total sterol content. The concentrations of sterols were in the following decreasing order: β-sitosterol > campesterol > brassicasterol > Δ-avenasterol > Δ-stigmastenol > stigmasterol. These results indicate that canola sprouts may have the potential as a natural source of dietary sterols and might be desirable for human nutrition.
