Characterization of phenolic compounds and anti-acetylcholinase activity of coconut shells

Tropical Fruits and Their Co-Products as Bioactive Compounds and Their Health Effects: A Review

“…Mahayothee et al [71] determined, in matured coconut meat, the presence of salicylic acid, p-hydroxybenzoic acid, syringic acid, m-coumaric acid, p-coumaric acid, gallic acid, caffeic acid, and catechin as its main phenolic compounds. Coconut shell fibers also have polyphenolic compounds including gallic acid (4.30 mg/g), syringic acid (0.42 mg/g), catechin (0.49 mg/g), and epicatechin (0.42 mg/g) [72]. Virgin coconut oil contains non-flavonoid compounds such as phenolic acids; the phenolic acids present are protocatechuic, vanillic, caffeic, syringic, ferulic, and p-coumaric acids [73].…”

Development of an oxyresveratrol incorporated bio-based smart nanocomposite coating with anti-corrosive, self-healing, and anti-microbial properties

“…The presence of higher amounts of polyphenols in the coconut shell is the reason for this enhanced response. 53 The coordination of the polyphenols via the lone pair of electrons in the heteroatom with the metal atom resulted in the formation of the protective coating. A tight chemisorption is formed by the coordination of the lone pair of electrons to the metal d-orbitals, and physisorption occurred due to the electrostatic attraction of charges on the compound and the surface charge.…”

Ultrasound-Homogenization-Assisted Extraction of Polyphenols from Coconut Mesocarp: Optimization Study

“…According to Li et al [30] with minor modification, the basic extraction condition: The ultrasonic power of 360 W, the ultrasonic time of 30 min, the ultrasonic temperature of 60 ℃ and the solid-liquid ratio of 1:15 g mL − 1 . Different solvents (water, methanol, methanol (60%, V methanol :V water ), ethanol, ethanol (60%, V ethanol V water ), acetone, acetone (60%, V acetone :V water ) were used to extract phenolic compounds from the CM and CE.…”
