GNPS Untargeted GC‐MS Metabolomic Analysis of Essential Oils From Duguetia lanceolata and Evaluation of Antimicrobial Activity

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolomic analysis of the essential oil of D. lanceolata leaves collected in winter revealed that they are mostly composed of sesquiterpenes, while those collected in autumn showed a predominance of monoterpenes. Both essential oils displayed antimicrobial activity against bacterial and fungal species.

Exploring the Antiproliferative Activity of Flavolignans From the Leaves of Casearia arborea (Salicaceae)

Chemistry &Biodiversity, Volume 22, Issue 12, December 2025.
ABSTRACT The Casearia genus (Salicaceae) is well known as a source of natural antitumor prototypes, as described for clerodane diterpenes. In this way, the dichloromethane phase from leaves of Casearia arborea was phytochemically evaluated in liquid chromatography coupled to high‐resolution mass spectrometry, furnishing flavonoid, flavolignan, and ...

Quality Control Strategies for Differentiation of Kalanchoe Species

Phytochemical Analysis, Volume 36, Issue 8, Page 2385-2400, December 2025.
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers and may exhibit quality issues because of misidentification from similar common names and anatomical similarities among related species used as feedstock. This study proposes an approach using UPLC‐MS/MSE and HPTLC, coupled
