Some physical and chemical properties of bitter melon (Momordica charantia L.) seed and fatty acid composition of seed oil

Abstract

Edible part and leaves of bitter melon (Momordica charantia L.) are used as food or medicine to control some diseases because of its antioxidant, antibacterial, anticancer, anti-hepatotoxic, antiviral, antiulcerogenic and larvicidal effects. Although fruits have considerable amount of seeds, they have not received much attention. In this study, some physical and chemical properties of the seed and also fatty acid composition of seed oil were determined. Oil content of the sample was determined by soxhlet apparatus as 26.10% in dried sample. Fatty acid composition was analyzed by GC-MS and seven fatty acids were identified and their ratios were determined in this seed oil. The main fatty acid was determined as α-eleostearic (45.60%). The other fatty acids were palmitic (3.69%), stearic (28.00%), oleic (12.45%), linoleic (8.90%), arachidic (0.71%) and gadoleic acids (0.65%).

Kudret narı (Momordica charantia L.) tohumunun bazı fiziksel ve kimyasal özellikleri ile tohum yağının yağ asitleri bileşimi

Abstract

Kudret narının meyvesi ve yaprakları antioksidan, antibakteriyel, anti-kanser, anti-hepatotoksik, antiviral, antiülserojenik ve larvisid etkileri dolayısıyla bazı hastalıkların kontrolü için gıda veya ilaç olarak kullanılabilmektedir. Kudret narı önemli oranda çekirdek içermesine rağmen genel olarak değerlendirilmemektedir. Bu çalışmada, kudret narı tohumunun bazı fiziksel ve kimyasal özelliklerinin yanında tohum yağının yağ asidi bileşimi belirlenmiştir. Kudret narı tohumunun yağ içeriği soxhelet cihazı ile tespit edilmiş olup, kurumadde üzerinden %26.10 olarak tespit edilmiştir. Elde edilen tohum yağının yağ asidi bileşimi GC-MS ile analiz edilmiş ve örnekte yedi farklı yağ asidi bulunduğu saptanmıştır. Örnekte en fazla bulunan yağ asidi α-eleostearik asit (%45.60) olarak tespit edilmiştir. Örnekte bulunan diğer yağ asitleri palmitik (%3.69), stearik (%28.00), oleik (%12.45), linoleik (%8.90), araşidik (%0.71) ve gadoleik (%0.65) asit olmuştur.
