Plant accession and insect infestation, rather than silicon supplementation, shape defence strategies of Arabidopsis halleri towards a leaf beetle

open access: yesPlant Biology, Volume 28, Issue 2, Page 407-419, March 2026.
Chemical and mechanical defences of a metal‐hyperaccumulating plant species Arabidopsis halleri were more influenced by plant accession (genetic background) and insect herbivory by a leaf beetle Phaedon cochleariae than by supplementation of the metalloid silicon.

Xanthone from Garcinia eugenifolia (Clusiaceae) [PDF]

open access: yes2010 International Conference on Science and Social Research (CSSR 2010), 2010
Studies on the twigs of Garcinia eugenifolia have led to the isolation of one xanthone 5,9-dihydroxy-8-methoxy-2,2-dimethyl-7-(3-methylbut-2-enyl)pyrano[3,2-b]xanthen-6(2H)-one (1) and one triterpenoid, sitosterol (2). Meanwhile, studies on the leaves of Garcinia eugenifolia provided another triterpenoid, friedelin (3).

New Anthracenone and Xanthenones From Tricholaena teneriffae With Antioxidant Activity: In Vitro and In Silico Studies

open access: yesChemistry &Biodiversity, Volume 23, Issue 1, January 2026.
Three novel phenolic compounds and one known benzoxanthenone are isolated from Tricholaena teneriffae. Compounds (1–3) demonstrate potent antioxidant activity, comparable to that of vitamin C, while compound (4) exhibits negligible activity. Docking studies are employed to validate the binding of the compounds to lipoxygenase‐3, providing evidence of ...
