Kiwi berry (Actinidia arguta (Sieb & Zucc) Planch. ex Miq. cv 'Longcheng No.2') is rich in polyphenols and has gained popularity in recent years. However, there is a lack of information on the specific polyphenol composition and antioxidant and enzyme inhibition activities of kiwi berries. This study aimed to analyze the anthocyanin and non-anthocyanin polyphenol profiles of kiwi berry using HPLC-HR TOF MS, compare their antioxidant capacity, and assess inhibition activity of digestive enzymes. Molecular docking was employed to investigate the interaction between cyanidin 3-O-sambubioside and digestive enzymes. The results revealed twenty non-anthocyanin polyphenols and ten anthocyanins, with seven anthocyanins and eight non-anthocyanins newly identified in kiwi berry. Kiwi berry exhibited potent antioxidant capacity and excellent α-glucosidase inhibition activity, suggesting its potential as a functional ingredient for managing early type-II diabetes through dietary interventions.

Kiwifruit (Actinidia chinensis), a recently commercialized horticultural crop, is rich in various nutrient compounds. However, the regulatory networks controlling the dynamic changes in key metabolites among different tissues remain largely unknown. Here, high-resolution spatiotemporal datasets obtained by ultraperformance liquid chromatography-tandem mass spectrometry methodology and RNA-seq were employed to investigate the dynamic changes in the metabolic and transcriptional landscape of major kiwifruit tissues across different developmental stages, including from fruit skin, outer pericarp, inner pericarp, and fruit core.

is mostly grown for its usage in the food, medical, and perfume industries, while it is also used as an attractive plant in parks, gardens, and homes. The use of essential oil may yield new results in relation to the antimicrobial activity of essential oils and their use mainly in extending the shelf life of foods. This study investigates the chemical composition and antimicrobial properties of essential oil (RDEO) using gas chromatography-mass spectrometry (GC-MS) and various bioassays to explore its potential applications in food preservation and microorganism growth control.
