“…Recently, Shah, Rahman, Shamsuddin, and Adzahan () described hydroxycinnamic acid profile (chlorogenic acid, caffeic acid, and coumaric acid) as well as flavanones (naringin, hesperidin, and narirutin) in Malaysian variety of Pummelo ( Citrus grandis L. Osbeck). Recently, Pei and Huang () have proposed a new method to determine traces of phenolic acids (p‐hydroxybenzoic acid, syringic acid, p‐coumaric acid, and ferulic acid) in fruit juice samples by using multiple monolithic fiber solid‐phase microextraction coupled with high‐performance liquid chromatography.…”
