Litsea glaucescens

In this regard, it has been proposed by other authors that the outer membrane of Gram-negative bacteria, constituted by phospholipid and lipopolysaccharides, provides resistance to antimicrobial treatments [ 57 ]. MICs values were calculated from the Optical Density data using the following equations: In other projects Wikimedia Commons. The correlation coefficients are shown in each graph.

Plant Material and Preparation of Extracts L. This page was last edited on 15 Februaryat Materials and Methods 2.

Antibacterial activity of extracts glaucesceens evaluated by the modified microdilution broth method [ 24 ]. The results of the antiproliferative activity evaluation of L.

In this regard, Borges et al. Although the evaluated samples have other phenolic constituents not identified in this work, it is possible that epicatechin and quercitrin could play an important role in the high antioxidant activity of ALGE and SULGE, since different studies have demonstrated that both phenolics are considered among the most antioxidant phenolic compounds [ 4546 ] and that capacity has been attributed to the catechol and chromane moieties that they have Figure 4.

On the other hand, ferric reducing power of the L. They are distinct in having a blue-green coloration to their undersides. It is native from southern North America, mostly in Mexico. Control bacterial cultures were incubated with DMSO 0.

Male flowers yellowish-white, 3. Bars with different superscript indicate statistical differences ALGE: Seeds are not available for the Mexican Bay.

View at Google Scholar M. Each year, around 2 million people are infected by antibiotic resistant bacteria in USA and thousands die due to infections with clinical complications [ 8 ]. These factors regulate the production glaucescfns secondary metabolites and subsequently the potential use of medicinal plants [ 17 ]. View at Google Scholar D. Thanks are due to Q. In addition, the lktsea of seasons on its antiproliferative activity was significatively different in three of the four cell lines studied here.

Total phenolic concentration was determined with Folin-Ciocalteu reagent, according to the method described by Velazquez et al. In the three studies, they found that autumn extracts presented the highest phenolic concentrations, in comparison with the samples of the other seasons. In addition, these compounds had shown a broad spectrum of biological activities, demonstrating the potential of plants as alternative drugs [ 13glaucedcens ].

A fairly uncommon shrubby tree best known for its use as a culinary spice. The cell line M As can be observed, the evident difference among them is the height of the chromatographic peaks related to the concentration of the phenolics. The capacity of L. In the present study, we evaluated the antioxidant activity of L. On the other hand, the lowest regression coefficient was obtained for the correlation between the data of the ORAC test versus CPC; however the value is still into an acceptable range.

The bark is brown, thick trunk.

It is well known that the antioxidant activity of natural products is strongly related to the content of phenolic compounds that they have, and the results obtained in this work agree with that fact. These findings provide new information about the seasonal effect on the PC ligsea biological properties of LG extracts. Litsea glaucescens Mexican Bay.

Leaves are leathery and elongated in shape, growing up to 3″. In addition, these facts determine also the redox potential and therefore the antioxidant activity of phenolic compounds [ 48 ]. In this context, natural agents emerge as a safe alternative to reduce the problem of the oxidative stress and antimicrobial diseases.

Significance level in Type I error was. In the same glaucescenw, Ndi et al. Description A small, evergreen tree growing to feet. Seeds were last available in June Although all the extracts inhibited the proliferation of human and murine cells lines, their effect was moderate.

Distributed by Mexico and Central America. Hardiness Hardy to short frosts. Structure of identified phenolic compounds in L. In addition, Pradeepa et al.
