The total and individual sterol content in 21 oat samples (seven cultivars grown at three different locations in Sweden) were analysed by gas chromatography after acid hydrolysis. The total sterol content in these oat cultivars varied between 350–491 µg g −1 of dry weight of kernel. The most abundant phytosterol was β‐sitosterol (237–321 µg g −1 ) followed by campesterol (32–46 µg g −1 ), Δ 5 ‐avenasterol (15–47 µg g −1 ) and stigmasterol (11–21 µg g −1 ). There was a statistically significant difference in total sterol content between cultivars ( p < 0.05) but no effect was found for cultivation location. Furthermore when contents of Δ 5 ‐avenasterol in hexane‐extracted oat oil and acid‐hydrolysed oat samples were compared, it was noticed that the content of Δ 5 ‐avenasterol was lowered due to acid hydrolysis. © 1999 Society of Chemical Industry
