Quassinoids from Picrasma Crenata

Natural Product Research, 2003
From woods of Picrasma crenata, a new stereoisomer dihydronorneoquassin was obtained together with others well knowns dihydronorneoquassin, parain, alpha-neoquassin, beta-neoquassin and quassin. The structures were determined by spectroscopic data and chemical evidence.

Quassinoids and Other Constituents from Picrasma crenata

Zeitschrift für Naturforschung B, 2001
Abstract 16-β-O-methylneoquassin and 16-β-O-ethylneoquassin, and four known quassi­ noids have been isolated together with coniferyl aldehyde, coniferin, cantin-6-one, 4,5-di-methoxycantin-6-one and (+)-neo-olivil from the wood of Picrasma crenata. Their structures were determined on basis of spectroscopic and X-ray analysis.

Development and Validation of an HPLC Method for Analysis of Picrasma crenata

Journal of Liquid Chromatography & Related Technologies, 2008
Abstract Picrasma crenata is a Brazilian tree, which is utilized to treat Diabetes mellitus, gastric perturbation, and hypertension. Quassinoids are the main constituents obtained from the wood of this plant. The relationship between the quassinoids and the biological effects reveal the interest of quantifying these constituents in P.

Araucaria angustifolia and Picrasma crenata extracts as potential agents for the control of phytopathogenic fungi of agricultural interest

Caderno Pedagógico
To expand knowledge about native species in southern Brazil, different types of extracts from the thin vinaceous bark of A. angustifolia and fragments of branches of P. crenata were evaluated. These were crushed and kept for fifteen days in contact with hydroalcoholic solutions at 70 % v/v and ethanolic (96 % v/v), seven days in the cold aqueous ...

The phylogeography of the stag beetle Dorcus montivagus (Coleoptera, Lucanidae): Comparison with the phylogeography of its specific host tree, the Japanese beech Fagus crenata

Entomological Science, 2023
Dorcus montivagus is a Japanese endemic stag beetle that feeds exclusively on dead beech wood, and its distribution is almost completely coincidental with that of beech forests.

Developmental stage-specific triterpenoid saponin accumulations in Ardisia crenata rhizosphere and its influence on rhizosphere microbial communities

Plant Biotechnology
Plant-specialized metabolites (PSMs) act as candidate drivers of rhizosphere microbiome assembly by recruiting specific microbial taxa. The resulting PSM–microbe interactions influence the host-plant fitness and population dynamics, ultimately impacting ...
