Chemical constituents derived from Drimys brasiliensis Miers (Winteraceae)

Natural Product Research, 2013
Phytochemical investigation on Drimys brasiliensis afforded the isolation and characterisation of four drimane sesquiterpenes: polygodial (1), warburganal (2), 1-β-(p-coumaroyloxy)polygodial (3) and 1-β-(p-methoxycinnamoyl)polygodial (4), as well as four flavonoids: quercitrin (5), astilbin (6), isoastilbin (7) and neoastilbin (8).

Bioherbicidal activity of drimane sesquiterpenes from Drimys brasiliensis Miers roots

Industrial Crops and Products, 2015
Abstract Drimys genus plants are known as source of mono- and sesquiterpenoids compounds with potential roles in plant–insect, plant–pathogen and plant–plant interactions. The aim of this study was to identify secondary metabolites in the Drimys brasiliensis Miers roots with the potential to act as natural herbicides, using wheat coleoptile ...

Sesquiterpene Polygodial from Drimys brasiliensis (Winteraceae) Down-Regulates Implant-Induced Inflammation and Fibrogenesis in Mice

Journal of Natural Products, 2020
Drimys brasiliensis (Winteraceae) has been investigated in traditional medicine for its anti-inflammatory properties to treat gastric ulcers and allergic and respiratory system diseases as well as for cancer treatment. In this work, we investigate the ability of the sesquiterpene polygodial, isolated from D.

Genetic diversity and structure of Drimys brasiliensis in southern Brazil: insights for conservation

Journal of Forestry Research, 2019
Population genetics studies are widely recognized for generating useful knowledge for biodiversity conservation. To date, however, little is known about the levels and distribution of genetic diversity of Drymis brasiliensis (Miers LC), a tree species from the Atlantic Rainforest.

Essential Oil from Leaves and Stem Bark of SoutheasternDrimys brasiliensisMiers (Winteraceae)

Journal of Essential Oil Research, 2008
Abstract The chemical composition of essential oils obtained from fresh leaves and stem bark of Southeastern Brazilian native Drimys brasiliensis Miers were analyzed by GC and GC/MS and 37 compounds were identified. The oils from fresh leaves showed the presence of monoterpenes (53.9%) and sesquiterpenes (38.4%), with sabinene (9.5%), myrcene (10.5 ...

Polygodial, a sesquiterpene isolated from Drimys brasiliensis (Winteraceae), triggers glucocorticoid-like effects on pancreatic β-cells

Chemico-Biological Interactions, 2016
Despite its common use, the synthetic glucocorticoid dexamethasone can cause several adverse effects, such as diabetes and insulin-related metabolic impairment. Thus, research on molecules that could provide the same anti-inflammatory response with milder side effects is constant. In this work the anti-inflammatory activity of the natural sesquiterpene

Anti-leishmanial and anti-trypanosomal potential of polygodial isolated from stem barks of Drimys brasiliensis Miers (Winteraceae)

Parasitology Research, 2011
Parasitic protozoan diseases affect the poorest population in developing countries. Leishmaniasis and Chagas disease have been included among the most important threats for public health in Central and South American continent, with few therapeutic alternatives and highly toxic drugs.

Antibacterial activity and toxicity of drimys brasiliensis

2012
Men have used medicinal plant properties to treat infectious diseases. Both the rise of emerging infectious diseases as the microbial resistance problem has stimulated the searching for new antimicrobial agents. This study evaluated the antibacterial activity and toxicity of crude extracts, fractions and pure compounds from Drimys brasiliensis.
