Antioxidant Chemistry of Phenolics in Chinese Herbal Medicines: A Holism‐Based Review

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Phenolic antioxidants in CHMs mainly include chalcone, stilbene, flavonoid, xanthone, and Diels–Alder‐type adducts. They undergo direct and indirect pathways to exert antioxidant action. The indirect pathway is transition metal‐chelating, while the direct pathway comprises several redox‐based reactions (e.g., SET and HAT) and RAF reactions.

Effects of Blanching on Phytochemical Retention, Antioxidant Capacity, and Microstructure of Banana Flower (Musa spp., Musaceae)

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
Hot‐water blanching (100°C, 1–5 min), citric acid treatment (1%–5% w/v in water), and microwave blanching (720 W, 30–40 s) were employed to modify the bioactive compounds of banana flowers. Microwave blanching for 40 s yielded the highest amounts of total phenolics (7.60 mg GAE/g), total flavonoids (4.90 mg QE/g), and antioxidant activity.
