Bioactive anthraquinone glycosides from Picramnia antidesma ssp. Fessonia

Phytochemistry, 1995
A bioactivity guided fractionation, using KB cells and brine shrimp assays, of the methanolic extract from the leaves of Picramnia antidesma yielded two known anthraquinones, aloe-emodin and aloe-emodin anthrone, and three new aloe-emodin C-glycosides, named picramnioside A, picramnioside B and picramnioside C.

Anthrone and Oxanthrone C-Glycosides from Picramnia latifolia Collected in Peru

Journal of Natural Products, 2004
Cytotoxicity-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 ...

Treatment of real wastewater with TiO2-films sensitized by a natural-dye obtained from Picramnia sellowii

Journal of Environmental Chemical Engineering, 2016
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.

Phylogenomic analysis of Picramnia, Alvaradoa, and Leitneria supports the independent Picramniales

Journal of Systematics and Evolution, 2017
AbstractPicramniales 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 Conservation
El 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.
