A Practical Protocol for a Comprehensive Evaluation of Sulfur Fumigation of Trichosanthis Radix Based on Both Non-Targeted and Widely Targeted Metabolomics

Frontiers in Plant Science, 2020
Trichosanthis Radix (TR) is one of the most severely sulfur-fumigated herbs in the market, whose transformation mechanism of chemical compositions and sulfur-fumigation markers of TR have not been clarified.

In silico detection of Cucurbitacin-E on antioxidant enzymes of model organism Galleria mellonella L. (Lepidoptera: Pyralidae) and variation of antioxidant enzyme activities and lipid peroxidation in treated larvae

Beni-Suef University Journal of Basic and Applied Sciences, 2022
Background In silico studies further provided predictive binding properties of selected ligands for inhibition of target protein. In the study, molecular binding poses of Cucurbitacin-E and antioxidant enzymes (glutathione-S-transferase (GST), superoxide

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

Pest Management Science, Volume 82, Issue 4, Page 3603-3612, April 2026.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Convergence and parallelism in the evolution of plant metabolism

Journal of Integrative Plant Biology, Volume 68, Issue 4, Page 1013-1031, April 2026.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...

Cucurbitacins: Specific Insect Attractants in Cucurbitaceae

Science, 1966
In vivo studies of cucurbitacins, the bitter principles present in Cucurbitaceae, indicated a quantitative relation between the concentrations of cucurbitacin in the plant and the degree of insect feeding. In vitro studies demonstrated the attractiveness of these compounds when they were separated from influences of other components of the host plants.

Advances in the biosynthesis, gene mining, and molecular mechanisms of cucurbitacin in Cucurbitaceae crops

Vegetable Research
Cucurbitacin, a highly oxidized tetracyclic triterpenoid compound, is a common secondary metabolite in Cucurbitaceae crops. Its presence imparts a bitterness to the fruit, significantly reducing its quality.

Phytochemical Analysis of Veratrum Alkaloids in Medicinal Veratrum Globules Using High‐Performance Liquid Chromatography Coupled With Tandem Mass Spectrometry

Biomedical Chromatography, Volume 40, Issue 3, March 2026.
ABSTRACT Veratrum L. species have been used in traditional medicine for centuries due to their bioactive properties, yet they also contain toxic steroid alkaloids that pose potential health risks when present in herbal preparations. Reliable analytical approaches are therefore essential to ensure product safety, protect consumer health and assess ...

Molecular Mechanism of Mulberrin Regulating Lipid Metabolism Homeostasis Based on the Gut–Liver Axis Fiaf/AMPK Signaling Pathway

Food Frontiers, Volume 7, Issue 2, March 2026.
The molecular mechanism for mulberrin regulating lipid metabolism homeostasis. ABSTRACT Lipid metabolism disorders and the induced metabolic diseases have risen to become one of the primary public health issues. Our preliminary experimental results confirmed that mulberry leaf flavonoid extract exhibited efficacy in lipid metabolism regulation; the ...

High‐throughput transcriptome mining and in silico screening reveal saccharide feeding stimulants for Cydia pomonella larvae

New Plant Protection, Volume 3, Issue 1, March 2026.
We identified and characterized the gustatory and ionotropic receptors of Cydia pomonella using transcriptomics and in silico approaches, linking candidate sugar receptors to larval feeding attraction. Functional assays and behavioral tests highlighted isoquercitrin as a key feeding stimulant, providing a foundation for olfactory‐ and taste‐based pest ...
