Extracts from Field Margin Weeds Provide Economically Viable and Environmentally Benign Pest Control Compared to Synthetic Pesticides.

open access: yesPLoS ONE, 2015
Plants with pesticidal properties have been investigated for decades as alternatives to synthetics, but most progress has been shown in the laboratory. Consequently, research on pesticidal plants is failing to address gaps in our knowledge that constrain

Two new rotenoid glycosides from the rhizomes of Stemona curtisii Hook. f

open access: yesNatural Product Research
Two new rotenoid glycosides named stemonal 11-O-β-D-glucopyranoside and 6-O-methylstemonal 11-O-β-D-glucopyranoside together with ten known metabolites were isolated from the rhizomes of Stemona curtisii. The chemical structures of the new compounds were

Dalbinol, a rotenoid from Amorpha fruticosa L., exerts anti-proliferative activity by facilitating β-catenin degradation in hepatocellular carcinoma cells

open access: yesOncoTarget, 2017
Hepatocellular carcinoma (HCC) is a highly malignant tumor, and the main cause of treatment failure is malignant proliferation. Aberrations in Wnt/β-catenin signaling are associated with HCC development.

From MS1 to Structure: A Van Krevelen–DBE–Aromaticity‐Based Framework for Annotating Specialized Metabolites via High‐Resolution Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 24, 30 December 2025.
ABSTRACT Rationale Classifying specialized metabolites in untargeted metabolomics remains a major challenge, particularly when relying solely on high‐resolution mass spectrometry (HRMS) data at the MS1 level. Traditional approaches using Van Krevelen diagrams often lack sufficient resolution to distinguish structurally similar metabolite classes ...

The Effects of Tea Wastes Prepared Using Different Composting Methods on the Seedling Growth and Selected Biochemical Properties of Maize (Zea mays var. indurata)

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
This study investigates the effects of tea‐waste‐based composts enriched with various organic fertilizers on the seedling growth and biochemical responses of local maize genotypes. Compost mixtures, especially those containing chicken manure and vermicompost, significantly enhanced plant development and antioxidant activity.
