Nanoenabled Phytochemical Mining: Gold Nanoparticle‐Mediated Recovery of Low‐Polar Secondary Metabolites From Plant Extract

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Green‐synthesized gold nanoparticles serve as tunable nanoadsorbents for selectively enriching low‐polarity secondary metabolites from Hypericum perforatum extracts. Structure‐ and polarity‐dependent interactions, optimized by solvent composition and incubation time, enable efficient recovery of phloroglucinols and xanthones for phytochemical ...

Managing Brown Rot Disease of Citrus Fruit Using Plant Extracts

open access: yesJournal of Phytopathology, Volume 174, Issue 2, March/April 2026.
ABSTRACT Brown rot, caused by Phytophthora nicotianae and P. citrophthora, is a major disease of citrus fruit, leading to significant economic losses globally. Conventional fungicides are commonly used to manage this disease, but concerns have been raised due to environmental persistence, human toxicity and the emergence of resistant strains.
