1. Drimys brasiliensis species, flowering plants. The traditional use of Drimys brasiliensis Miers (Winteraceae) in the south of Brazil to reduce cholesterol has not been described in scientific. The essential oils obtained from Southern Brazilian native Drimys brasiliensis Miers and Drimys angustifolia Miers were analyzed by GC and GC/MS. The oils.

The inhibitory effects could also be observed at the cellular level of E. For both organs, the fractions obtained with the solvent n-hexane had higher levels of inhibitory activity, which suggests that substances with allelopathic potential present in D.
Journal of Pharmaceutical Sciences, v. To determine the doses of D. Thirty-five subfractions of 35 mL each were brwsiliensis. Author information Article notes Copyright and License information Disclaimer.
Drimanes from Drimys brasiliensis with leishmanicidal and antimalarial activity
The minimum shoot length of seedlings treated with hexane 7. Another serious public health problem is malaria, which is caused by protozoa of the genus Plasmodium and is transmitted to humans by female Anopheles mosquitoes, producing fever and other symptoms. Anti-leishmanial and anti-trypanosomal potential of polygodial isolated from stem barks of Drimys brasiliensis Miers Winteraceae. Journal of Experimental Marine Biology and Ecology, v.
Isolation and phtytotoxicity of terpenes from Tectona grandis. The roots grown in the presence of D. This paper analyses chloroform and methanol extracts of the stem bark, branches and leaves of D. Photodiode array detector; RS: A linear relationship was not observed between hypocholesterolemic activity and dose since other unidentified mechanism could be involved.
These results highlight the importance of the p-hydroxycinnamoyl group for the leishmanial inhibition, which may be explained by the lipophilicity associated with the aromatic group and the possibility of hydrogen bond formation to maintain the biological activity.
Early growth of E. Received Jun 26; Revised Jul These compounds exhibit antifungal Castelli et al. Spirulina platensis effects on the levels of total cholesterol, HDL and triacylglycerols in rabbits fed with a hypercholesterolemic diet. The mobile phase for the three first substances consisted of acetonitrile and water pH 3.
Additional evidence for the anti-inflammatory and anti-allergic properties of the sesquiterpene polygodial. Protein measurement with the Folin phenol reagent. For the variables that showed no significant differences between treatments, the results were presented in tables. Its interference with agricultural productivity is primarily due to its highly aggressive growth patterns, its intense production capacity and the longevity of its seeds COSTA et al.
Values for the hexane fraction root extract treated seedlings could not be obtained for the 0. From each photograph, 10 central cells of the metaxylem were measured with the aid of Image Pro Plus 5.
Thus, this study aimed to determine the hypocholesterolemic potential of D. The Possible Mode of Action.
Anti-lipid Potential of Drimys brasiliensis
All experiments were conducted in accordance with ethical standards for animal experiments; principles internationally accepted for laboratory animal use;[ 17 ] and the Brazilian rules. The extracts obtained from the different parts the stem bark, brailiensis and leaves of D.
Allelopathic potential of Sapindus saponaria L. Casali for assistance with plant material collection, Prof.
Previous reports have suggested that toxicity levels vary depending on the plant organ used during the extraction. Caffeic and ferulic acids were found in the extract at concentrations of Extracts of Julocroton triquetera Dichorisandra sp. Thus, species of Drimys are promising in the search for phytochemicals capable of acting as natural herbicides. A slow-growing plant, it barely reaches a height of 1.
The ecosystem and evolutionary contexts of allelopathy. Bioassays were conducted in Petri dishes brasiliensix cm in diameter containing two sheets of filter paper moistened with 5 mL of either the sample fractions or the brzsiliensis control solution.

Services on Demand Journal. Conflicts of interest There are no conflicts of interest. Leaf and root extracts of the invasive shrub, Lonicera maackiiinhibit seed germination of three herbs with no autotoxic effects.
Clinically, two rats of GDbP had epistaxis, difficulty breathing, and diarrhea. The identification of these phytotoxins may contribute to a better understanding of the allelopathic potential of D. The relative weight gain was calculated relative to the initial weight day 0.
From this solution, dilutions of 0.
