Anthrone and Oxanthrone C-Glycosides from Picramnia latifolia Collected in Peru
Journal of Natural Products, 2004Cytotoxicity-based, bioassay-guided fractionation of the chloroform-soluble extracts of both the roots and leaves of Picramnia latifolia led to the isolation of two new anthrone C-glycosides, picramniosides G (1) and H (2), two new oxanthrone C-glycosides, mayosides D (3) and E (4), and a new benzanthrone natural product, 6,8-dihydroxy-10-methyl-7H ...

Abstract A natural dye extracted from Picramnia sellowii (Chokanari) was used to prepare sensitized TiO 2 films. Dyes and heterotrophic microorganisms present in wastewater were treated by photocatalysis using visible light. A factorial design 2 3 was employed to select the operational conditions to sensitize TiO 2 films.

Biochemical Systematics and Ecology, 2003
The structures of the secondary metabolites, including fatty acids, of the genera Picramnia and Alvaradoa (Picramniaceae) are surveyed. Neither the fatty acid profiles nor the structures of the anthraquinones and sugar linked anthracenone derivatives characteristic of both genera indicate close relationships between the Picramniaceae and any other ...

Two highly oxygenated nortriterpenes, picraviane A and B, were isolated from the ethanolic extract of Picramnia glazioviana Engl. The structures were determined by analysis of HRMS and 2D NMR spectroscopic data. Single-crystal X-ray diffraction data was also obtained for picraviane B.

Phylogenomic analysis of Picramnia, Alvaradoa, and Leitneria supports the independent Picramniales
Journal of Systematics and Evolution, 2017AbstractPicramniales is a recently established monotypic order that has not yet acquired a stable position on the phylogenetic tree of flowering plants. While Picramnia and Alvaradoa were transferred from Simaroubaceae (Sapindales) into Picramniaceae (Picramniales), Leitneria was transferred from the “hamamelids” into Simaroubaceae.

Picramnia dictyoneura (Picramniaceae), un nuevo registro para Cuba
Caribea – Caribbean Journal of Plant ConservationEl género Picramnia en Cuba ha sido reconocido tradicionalmente por la presencia de dos especies: P. pentandra y P. reticulata. La revisión de especímenes de herbario recolectados en Cuba oriental reveló la existencia de materiales cuyos caracteres morfológicos no corresponden a las especies previamente registradas para el país.
