摘要：

This study analyzed the chemical composition and antioxidant properties of proanthocyanidins (PAs) in Chinese quince fruits at six growth stages. UPLC-QTOF-ESI-MS/MS and MALDI-TOF-MS identified and quantified the chemical composition, while radical scavenging ability assessed antioxidant capacities. PA concentration peaked during mid-growth and declined as fruits ripened. The highest total proanthocyanidin content occurred in August (1776.69 +/- 56.97 mg PB2/100 g FW). Catechin and epicatechin were the primary PA subunits, forming trimers to tetradecamers and higher degrees of PAs. The PA extr...
