Bio‐guided fractionation of (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid from Abelmoschus sagittifolius root as a potent α‐glucosidase inhibitor: An integrated in vitro and in silico study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abelmoschus sagittifolius stands out as a valuable medicinal source for developing functional food targeting type 2 diabetes. This study investigated the α‐glucosidase inhibitory potential of an active fraction obtained from A. sagittifolius roots (ASR), enriched in (9Z)‐5,8,11‐trihydroxyoctadec‐9‐enoic acid (OA), using both enzyme ...

Disclosing the production of fungal chitinases and proteases using insect by‐products as substrates in solid‐state fermentation

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The world population is projected to reach nearly 9.7 billion by 2050, significantly increasing the demand for novel and sustainable protein sources. Edible insects, such as Tenebrio molitor, emerge as promising alternatives due to their high nutritional value, but adult insects and frass are direct and abundant by‐products of this ...

Synthesis of Borneol‐Polymers as Fluorescent Sensors for Pollutant Detection

Macromolecular Symposia, EarlyView.
ABSTRACT In this work, a borneol‐derived monomer was employed to synthesize two novel copolymers, poly(vinyl acetate‐co‐bornyl methacrylate) (CopBM‐1) and poly(p‐acryloyloxybenzaldehyde‐co‐bornyl methacrylate) (CopBM‐2), via radical copolymerization. Both copolymers demonstrated aggregation‐induced emission in DMF at concentrations exceeding 0.04 wt.%.

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

Pest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in
