ZIZIPHUS OIL …. A POTENTIAL SOURCE OF BIOACTIVE COMPOUNDS AND ESSENTIAL FATTY ACIDS
|
|
Abstract: Ziziphus spina Christi or Nabg, the Haven tree, is a tropical tree grown in Egypt and other tropical countries since long time ago and known as popular Egyptian fruit. Nabg fruit composed of edible part and seed (consist of husk and kernel) which constitute 75.85%, 24.15% (18.63 and 5.5%)of total fruit weight, respectively. The average weight of the fruit, seed and kernel are 1.40, 0.32 and 0.073g, respectively.
Oil was extracted and recovered from different parts of fruit; edible part (pulp), husk and kernel and its percentages was 1.2%. 1.9 and 31.3%, respectively.
Fatty acids profile of oils from different parts of fruit was identified by GLC. Oleic acid was the predominant fatty acid followed by linoleic acid, while essential fatty acids; eicosapentaenoic (EPA) and docosahexaenoic (DHA) were highly found in the edible part. γ-linolenic acid was also detected in an appreciable amount in the fruit parts (2.5%).
Bioactive compounds such as fat-soluble vitamins were determined in all fruit parts using Normal-phase HPLC. γ-Tocopherol was the major tocopherols followed by -tocopherol. -carotene was found in a high level in seed oil (60.1 mg/100g-1) followed by kernel oil (30.0 mg/100g-1) and sterol content was also determined in different extracted oils, -siterol was the main components followed by stigmasterol , 5-avenasterol and campesterol.
