Phytosterols in sea buckthorn (Hippophae rhamnoides L.) seed oil extracted by cold pressing, hexane, and supercritical carbon dioxide were identified by GC-MS and FID. Compounds identified were campesterol, clerosterol, lanosterol, sitosterol, beta-amyrin, sitostanol, Delta(5)-avenasterol, Delta(7(28))-stigmasta-en-ol, alpha-amyrin, Delta(5,24(125))-stigmastadienol, lupeol, gramisterol, Delta(7)-sitosterol, cycloartenol, cycloeucalenol, Delta(7)-avenasterol, 28-methylobtusifoliol, 24-methylenecycloartanol, erythrodiol, citrostadienol, uvaol, and oleanol aldehyde. Sitosterol and Delta(5)-avenasterol were, quantitatively, the most important phytosterols. Total sterols and most individual sterols differed significantly (P >= 0.05) among all three extraction methods with supercritical carbon dioxide extracting the highest total sterol levels (1640 mg/100 g oil) and cold pressed the lowest levels (879 mg/100 g oil).
