Phytochemistry, 2021 From the aerial extracts of Coptosapelta diffusa (Champ. ex Benth.) Steenis, twenty-one compounds were isolated and identified by means of column chromatography and NMR and MS techniques, respectively. Amongst, ten ones were determined to be undescribed compounds including six seco-iridoid glucosides (1-6), 2-(hydroxymethyl)-1,2,3,4 ...

Comparative anatomy and genetic bases of fruit development in selected Rubiaceae (Gentianales). [PDF]
Am J Bot, 2021 Abstract Premise The Rubiaceae are ideal for studying the diversity of fruits that develop from flowers with inferior ovary. We aimed to identify morpho‐anatomical changes during fruit development that distinguish those derived from the carpel versus the extra‐carpellary tissues.

Phylogenomics and topological conflicts in the tribe Anthospermeae (Rubiaceae). [PDF]
Ecol EvolGenomic data have provided new opportunities to address phylogenetic incongruence and its bases. Our work shows notable intergenomic incongruence in a tribe of the coffee family, and the null hypothesis of congruence among all sequenced loci in the individual genomes was surprisingly rejected for plastid data.

New chromosome counts on Rubiaceae from Africa and the Western Indian Ocean islands
Nordic Journal of Botany, Volume 2023, Issue 5, May 2023., 2023 Cytological studies can provide important insights into circumscription and relationships within plant groups. Nevertheless, there is a considerable lack of cytological information, especially for large and complex groups such as the coffee family (Rubiaceae) and for plants from Africa and the Western Indian Ocean islands. In the present study, 110 new
