Comparative analysis of <i>Zanthoxylum armatum</i> essential oils from four cultivars: Chemical compositions, antioxidant activities, and antibacterial activities.

ABSTRACT: Chemical compositions, antioxidant activities and antibacterial activities of essential oils (EOs) extracted from four Zanthoxylum armatum cultivars were comparatively analyzed. Results showed that EO yield of Ziyang Qinghuajiao (ZQ) (3.82 ± 0.16 %) fruits was significantly higher than those of Tengjiao (TJ), Jiuyeqing (JYQ), and Yehuajiao (YHJ). Approximately 90 volatile organic compounds (VOCs) were identified, with TJEOs and JYQEOs exhibiting similar chemical profiles that differed significantly from those of ZQEOs and YHJEOs. ZQEO demonstrated superior antioxidant activity and antidiabetic potential due to higher β-phellandrene and eucalyptol contents. TJEO and JYQEO exhibited stronger antibacterial activity against Escherichia coli, Staphyl
