Metabolomic Mapping of Greek Olive Leaves by Untargeted NMR‐Based Profiling and LC–HRMS Dereplication

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Olive tree leaves are phytochemically rich yet insufficiently valorised in terms of systematic cultivar‐based characterisation and exploitation, and are an abundant olive industry side‐product. This study represents the first large‐scale metabolome mapping based on 340 leaf extracts from five major Greek cultivars (Amfissis, Koroneiki, Manaki,

UHPLC‐DAD‐HRMS2 Characterization of Novel Dihydrochalcone Conjugates From the Antiviral Mansoa hirsuta Extracts: Diagnostic Fragmentation Pathways and Dereplication of Oligomeric Polyphenols

Journal of Mass Spectrometry, Volume 61, Issue 11, November 2026.
ABSTRACT High‐resolution mass spectrometry (HRMS) coupled with ultra‐high‐performance liquid chromatography (UHPLC) enables rapid characterization of complex polyphenolic constituents in medicinal plants. Mansoa hirsuta (Bignoniaceae), a neotropical liana traditionally used to treat infectious diseases, remains poorly characterized chemically.

Interference of Phenylethanoid Glycosides from Cistanche tubulosa with the MTT Assay

Molecules, 2015
The MTT assay, as a screening method, has been widely used to measure the viability and proliferation of cells. However, it should be noted that MTT assay may not accurately reflect the effect of Cistanche tubulosa ethanolic extract on EA.hy926 cells ...

A New Lignan Glycoside and Phenylethanoid Glycosides from Strobilanthes cusia Bremek.

ChemInform, 2004
The root of Strobilanthes cusia BREMEK. (Acanthaceae), popularly known as Da-Ching-Yeh, has been commonly used in traditional Chinese medicine. It is used to treat influenza, epidemic cerebrospinal meningitis, encephalitis B, viral pneumonia, mumps, and severe acute respiratory syndrome (SARS). In this study, we found a new lignan glycoside (6) and two

Phenylethanoid Glycosides Isolated from Paraboea Paniculata [PDF]

Natural Product Communications, 2012
Phytochemical studies of the leaves and rhizomes of Paraboea pa niculata (Gesneriaceae) are reported for the first time. Three phenylethanoid glycosides were isolated and characterized as 3,4-dihydroxyphenethyl-(3″- O-β-D-apiofuranosyl)- β-D-glucopyranoside, calceoralarioside E, and acteoside.

Exploring the Neuropharmacological Potential of Ligustrum sinense Relevant to Parkinson's Disease: In Vivo and In Silico Study

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Ligustrum sinense (L. sinense) leaf extract exhibited moderate antioxidant activity (DPPH IC50 = 73.56 ± 2.18 µg/mL) and was evaluated for neuropharmacological effects at 200 and 400 mg/kg using elevated plus maze, open‐field, hole‐cross, and hole‐board tests.

Light and Nutrient Dependent Responses in Secondary Metabolites of Plantago lanceolata Offspring Are Due to Phenotypic Plasticity in Experimental Grasslands. [PDF]

PLoS ONE, 2015
A few studies in the past have shown that plant diversity in terms of species richness and functional composition can modify plant defense chemistry. However, it is not yet clear to what extent genetic differentiation of plant chemotypes or phenotypic ...
