Introduction Fatty acids and monoglycerides are two groups of lipid compounds that can be produced from vegetable oils or animal fats. Vegetable oil is a triglyceride compound, also known as triacylglycerol or glycerol triester, with the acyl group that comes from a fatty acid. The type of vegetable oil is determined by the kind of fatty acid that is bound to triglycerides. Triglycerides of vegetable oils comprises of certain major fatty acids with some other minor fatty acids. For example, the coconut oil Cocos nucifera L. , the castor oil Ricinus communis L. , the olive oil, the sunflower oil, the palm oil contains 54 lauric acid 1 , 93 ricinoleic acid 2 , oleic acids 3 , oleic and linoleic acid 4 and palmitic acid 5 , respectively. Some types of fatty acids such as EPA and DHA have essential functions in health such as reducing coronary heart disease risk factors, preventing certain cancers and im

Virgin coconut oil is obtained by wet processing of coconut milk using fermentation, centrifugation, enzymatic extraction, and the microwave heating method. Presently, VCO has several positive effects and benefits to human health, hence, it is regularly consumed and widely known as a unique functional food. VCO contains lauric acid (45 to 52 %). By lipase in the digestive system, VCO can undergo a breakdown into lauric acid, 1-monolaurin, and 2-monolaurin. These components have both hydrophilic and lipophilic groups and are also recognized as excellent antimicrobial lipids. Furthermore, lauric acid and monolaurin can be used as antibacterial, antifungal, and antiviral with broad-spectrum inhibition. Lauric acid and monolaurin have a strong ability to destroy gram-positive bacteria, especially S. aureus, fungi such as C. Albicans, and viruses including vesicular stomatitis virus (VSV), herpes simplex virus (HSV), and visna virus (VV). Lauric acid and monolaurin interact with certain functional groups located in the cell membrane and can cause damage to the cell. In general, the potential of VCO as healthy food is contributed by lauric acid and monolaurin which are antimicrobial agents.

Telah dilakukan penelitian tentang skrining fitokimia pada ekstrak daun flamboyan (Delonix regia. Raf). Penelitian ini bertujuan untuk mengetahui senyawa metabolit sekunder pada ekstrak daun flamboyan meliputi flavonoid, alkaloid, saponin, tanin dan fenolik. Penelitian diawali dengan pembuatan ekstrak metanol, kloroform dan n-heksan daun flamboyan menggunakan metode maserasi. Masing-masing ekstrak selanjutnya dilakukan skrining fitokimia. Hasil skrining fitokimia menunjukkan semua ekstrak daun flamboyan mengandung flavonoid, alkaloid, tanin dan fenolik. Kandungan saponin tidak terdapat pada ekstrak kloroform dan n-heksan sedangkan hasil positif saponin terdapat pada ekstrak methanol daun flamboyan. Kata Kunci: Daun Flamboyan (delonix regia. Raf), Skrining Fitokimia, Metabolit Sekunder
