Chemometric and metabolomic profiles of global tea brands sold in Saudi Arabia.

ABSTRACT: Despite extensive global research on Camellia sinensis, comprehensive studies on its chemical composition remain limited in many regions, including Saudi Arabia, restricting insights into its health benefits and quality. This study aimed to characterize the mineral, antioxidant, phenolic, and phytochemical profiles of 20 commercial tea brands imported from Sri Lanka, India, the United Arab Emirates, Saudi Arabia, and the United Kingdom. Mineral content was assessed via inductively coupled plasma mass spectrometry (ICP-MS), phytochemicals were analyzed by gas chromatography-mass spectrometry (GC-MS), antioxidant capacity was evaluated using the DPPH assay, and total phenolic content (TPC) was determined with the Folin-Ciocalteu method. Chemometric analyses, including principal component ana
