Abstract
The unconventional oil in Sudan is available from Vangueria madagascariensis (Rubiaceae). This study was carried outtoevaluate the Oil Components of Vangueria madagascariensis seeds. The oil and protein contents were 40.0, 22.2% respectively in the seed. The oil was extracted using cold extraction (CE) and Soxhlet extraction (SE) methods. Fatty acids, tocopherolsandsterol were determined by GC–MS and HPLC, respectively. The major fatty acids in the seed oil extracted by CE and SE were oleic 10.5, and 10.4%, linoleic 63.1 and 63.4%, palmitic 9.7 and 9.8% and stearic 5.1 and 5.4%, respectively. The tocopherol content of CE and SE extracted oils amounted to 110.5 and 107.7 mg/100 g oil, respectively, with beta -tocopherol as the predominant tocopherol in the oil. Sterols profile shows that the major components are β-sitosterol 45.24%, campesterol 22.65% and stigmasterol 20.08% in the oil. Vangueria madagascariensis oil seed deserve further attention and investigations.
