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 ...

Insights into glandular trichome biology from analysis of organ‐specific gene expression programmes in cannabis, hop and tomato

open access: yesThe Plant Journal, Volume 125, Issue 6, March 2026.
Significance Statement This study of three glandular trichome‐producing species (cannabis, hop and tomato) defines tissue‐specific transcriptomic atlases for five organs (trichome, flower, leaf, stem and root), providing co‐expression and gene regulatory networks and identifying candidate regulators of specialised metabolism in trichomes of each ...

Characterizing the Metabolic Fingerprint and Anti-inflammatory Activity of Hypericum gentianoides [PDF]

open access: yes, 2008
In this paper we characterize the metabolic fingerprint and first reported anti-inflammatory activity of Hypericum gentianoides. H. gentianoides has a history of medical use by Native Americans, but it has been studied very little for biological activity.

Antigenotoxic prenylated flavonoids from stem bark of Erythrina latissima [PDF]

open access: yesPhytochemistry, 2017
A series of prenylated flavonoids was obtained from antigenotoxic extracts and fractions of stem bark of Erythrina latissima E. Mey (Leguminosae). In addition to five constituents never reported before, i.e. (2S)-5,7-dihydroxy-2-(4-hydroxy-2-(prop-1-en-2-yl)-2,3-dihydrobenzofuran-6-yl)chroman-4-one (erylatissin D), (2S)-5,7-dihydroxy-2-(4-methoxy-2 ...

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

open access: yeseFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...
