Shredded tuna fortified with banana blossoms as an anti-diabetic food candidate: an investigational in silico study

Fish shredded is nutritious and has a soft texture, less stringy than shredded beef. The compounds in tuna shredded fortified with banana blossoms and their potential as antidiabetic are not yet known. The purpose of this study was to identify phytochemical bioactive compounds in tuna shredded fortified with banana blossoms and to study its potential as an antidiabetic functional food in silico. The 70% fortified tuna shreds were extracted using hexane, followed by ethyl acetate and finally using methanol. The methanol filtrate was evaporated to obtain methanol extract of shredded fish and analyzed using LC-HRMS. Phytochemical compounds were analyzed for antidiabetic potential in silico using Open Babel GUI software version 2.4.1, PyRx 0.8 (The scrips Research Institute), PyMOLTM 1.7.4.5, and Discovery Studio Visualizer (2021). The methanol extract of banana heart fortified tuna fish contained 32 compounds. The results of docking the compounds against the a-glucosidase receptor showed that the compound that had a lower or the same binding affinity with acarbose (-8.00 Kcal/mol) and native ligand (-6.00 Kcal/mol) was flurandrelonide (-9.40 kcal/mol), Quercetin-313-D-glucoside (-9.30 kcal/mol), sakuranetin (-8.80 kcal/mol), curcumin (-7.70 kcal/mol), ar-turmerone (-7.20 kcal/mol), nootkatone (-7.20 kcal/mol), and ferulic acid (-6.90 kcal/mol). The lower the binding affinity value, the stronger the inhibition of a-glucosidase. Phytochemical compounds in shredded tuna fortified with banana blossoms that may act as antidiabetic agents through in silico a-glucosidase inhibition are flurandrelonide, quercetin-313-glucosidase, sakuranetin, curcumin, ar-turmerone, and ferulic acid.
