Physicochemical properties and partial biological activities of Hangzhou white tea which was manufactured with fresh leaves from Hangzhou were studied.The sensory quality,physical and chemical properties and partial biological activities of Hangzhou white tea with different storage time were analyzed,with Fuding white tea as comparison.The results showed that the contents of water-soluble extract and tea polyphenols in Hangzhou white tea were significantly higher than those in Fuding white tea(P＜0.05),but the contents of amino acid and soluble sugar were lower than the latter.The activities of scavenging free radical(DPPH)and inhibiting α-glucosidase of Hangzhou white tea manufactured in 2023 were better than those of Hangzhou white tea made in 2020.
