: In today's society, the risk of cardiovascular disease is steadily rising. The fatty acid composition of three local fermented food condiments (dawadawa, ogiri igbo, and ogiri okpei) purchased from different markets in Aba, Nigeria, was studied using gas chromatography mass spectrometry (GCMS) in order to look for alternative natural fermented food condiments that are absorbed in the body without having many health implications. The fatty acid profiles revealed the presence of caproic acid in all condiments, with dawadawa (0.916%), ogiri igbo (0.767%) and ogiri okpei (6.167%). Linoelaidic acid was observed to be present in the dadwadawa (1.608%) and ogiri igbo (7.050%) condiments only, while oleic acid was present only in ogiri okpei (0.901%). Both ogiri igbo (2.939%) and ogiri okpei (1.419%) showed the presence of palmitoleic acid, while isovaleic acid was also observed to be present in both dawadawa (2.298%) and ogiri igbo (12.307%) condiments. Butanoic acid (35.779%), palmitic acid (4%) and 4-Methyloctanoic fatty acid (1.491%) were found only in the ogiri igbo condiments. The three native condiments were devoid of linoleic acid (omega-6 group) and alpha-linolenic acid (omega-3 group). The lipid profile of the three condiments differed significantly, with the ogiri igbo having a higher fatty acid content than the dawadawa and ogiri okpei.

: Many studies have focused on the phytochemical, antioxidant, and mineral content of red monkey kola (Cola Millenii K. Schum), but there is little or no information on the fatty acid composition of this unique and underutilized plant, which is widely consumed in Africa. With this in mind, the fatty acid composition of the red monkey kola fruit and bark obtained in Gariki, Enugu State, was determined in order to determine the type of fatty acid present in the plant as well as its benefits for its consumers. The GCMS chromatogram data revealed the presence of five fatty acid compounds in the fruit sample, including oleic acid (8.094%), stearic acid (0.297%), petroselinic acid (1.237%), palmitic acid (2.290%), and cis-10-nonadeconic acid (0.183%). The bark sample contained cis-10-nonadecenoic acid (8.946%), palmitic acid (2.911%), petroselinic acid (1.881%), stearic acid (0.539%), and 18-nonadecenoic acid (0.366%). Oleic acid was found to be only present in the fruit sample, as the presence of this omega 9 fatty acid conferred numerous health benefits to the consumers. Other unsaturated acids such as petroselinic acid and saturated fatty acids like stearic acid are important compounds used as anti-inflammatory, anti-aging and as a supporting substitute for trans-fat in vegetable oils.
许多研究都集中在红猴可拉(Cola Millenii K. Schum)的植物化学、抗氧化剂和矿物质含量上，但关于这种独特且未被充分利用的植物的脂肪酸组成的信息很少或根本没有，这种植物在非洲被广泛食用。考虑到这一点，对在埃努古州Gariki获得的红猴考拉果和树皮的脂肪酸组成进行了测定，以确定该植物中存在的脂肪酸类型及其对消费者的益处。GCMS色谱数据显示，果实样品中存在油酸(8.094%)、硬脂酸(0.297%)、石油亚麻酸(1.237%)、棕榈酸(2.290%)和顺-10-壬烷酸(0.183%)5种脂肪酸化合物。树皮样品中含有顺式-10-壬烯酸(8.946%)、棕榈酸(2.911%)、石油亚麻酸(1.881%)、硬脂酸(0.539%)和18-壬烯酸(0.366%)。油酸被发现只存在于水果样本中，因为这种- 9脂肪酸的存在给消费者带来了许多健康益处。其他不饱和脂肪酸，如石油亚麻酸和饱和脂肪酸，如硬脂酸是重要的化合物，用于抗炎、抗衰老，并作为植物油中反式脂肪的辅助替代品。
