The leaves of Chromolaena odorata (Asteraceae) are exploited extensively in West and Central African ethnopharmacy for the treatment of a wide range of conditions, despite this being a non-native species established in the last 50 years. With the objective of seeking bioactive principles, the
There are estimated to be more than 20,000 species of plants in Venezuela, of which more than 1500 are used for medicinal purposes by indigenous and local communities. Only a relatively small proportion of these have been evaluated in terms of their potential as antitumor agents. In this study, we
From the flowers of Chromolaena odorata (Eupatorium odoratum) four flavanones, isosakuranetin (5,7-dihydroxy-4'-methoxyflavanone) (1), persicogenin (5,3'-dihydroxy-7,4'-dimethoxyflavanone) (2), 5,6,7,4'-tetramethoxyflavanone (3) and 4'-hydroxy-5,6,7-trimethoxyflavanone (4), two chalcones,
BACKGROUND
Immune dysregulation has been implicated in the pathogenesis of many diseases. Macrophages play a crucial role contributing to the onset, progression, and resolution of inflammation. Macrophage inflammatory mediators are of considerable interest as potential targets to treat inflammatory
In this study, we investigated serum interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) after ingestion of aflatoxin B1 (AFB1) in rats. We also studied the effects of nitric oxide (NO) on the stomach after consumption of AFB1. Therefore, we hypothesized that a standard
Two new flavonoid glycosides, (1, 2), and eleven known compounds, (3-13), were isolated from from a 70% EtOH extract of the leaves of Chromolaena odorata (Asteraceae). Their structures were elucidated by 1D and 2D NMR spectroscopic interpretation as well as by chemical studies. The newly isolated
Phytochemical investigation of Chromolaena laevigata led to the isolation of a new cadinene-sesquiterpene, chromolaevigone glucoside (1), along with nine known compounds: daucosterol (2), stigmasterol glycoside (3), stigmasterol (4), β-sitosterol (5),
