Male flowers yellowish-white, 3. On the other hand, previous studies have reported that phenolic compounds exhibit different mode of actions against cancerous cell lines, for example, the induction of apoptosis, the cell cycle arrest, and the prevention of carcinogen metabolic activation with the subsequent cell death [ 5556 ].

Its leaves have been traditionally used as food seasoning, as litxea as remedy in folk medicine against central nervous system illness, depression, colic, pain, vomit, and diarrhea [ 21 ]. The bark is brown, thick trunk. On the other hand, the porins in outer membrane could regulate too the penetration of hydrophilic substances and reduce the fluidity of the lipopolysaccharides layer, decreasing the rate of transmembrane diffusion [ 58 ].

In addition, the increase in the enzymatic activity of PAL is related to an adaptation of the plant to stress [ 36 ]. Plant Material and Preparation of Extracts L. Flower in clusters; Inflorescences male and female axillary, umbellate, solitary or clustered along branches sharp cutting, c. Leaves are leathery and elongated in shape, growing up to 3″.

The plant is used as a spice, notably as a substitute for bay Laurus nobilis.

MICs values were calculated from the Optical Density data using the following equations: Bacterial cell cultures were treated with different concentrations of L.

Many parts of the plant contain essential oils that are reminiscent of the bay leaf. Antiproliferative activity of L.

The correlation coefficients are shown in each graph. Glaucesfens example, in a study performed by Herrera-Carrera et al. View at Google Scholar C. In this context, natural agents emerge as a safe alternative to reduce the problem of the oxidative stress and antimicrobial diseases.

Despite the interesting properties that this Mexican plant has, subsequent studies are required to support its effectiveness and safety doses for human applications. View at Google Scholar Y. Clearly, antioxidant activity was the most important with respect to the other two. IC glaycescens values were calculated using nonlinear regression analysis in Microsoft Excel software.

Antibacterial Assay Antibacterial activity of extracts was evaluated by the modified microdilution broth method [ 24 ]. Makes a good candidate for container culture.

Seasonal Effect on the Biological Activities of Litsea glaucescens Kunth Extracts

On the other hand, the antibacterial activity of L. This study shows the gglaucescens effect on the antioxidant, antiproliferative, and antimicrobial activities of L.

Flowers are small, white-green in color. F6 murine B-cell lymphoma was glaicescens by Dr. Additionally, the four extracts exhibited an interesting ability to liteea as preventive and chain-breaking antioxidants with activity against biological and synthetic radicals. On the other hand, phenolic glwucescens are associated with a wide range of biological activities. The three types of tests performed in this study provided evidences about the high ability of the four extracts to transfer electron and hydrogen atoms to stabilize free radicals and reduce metals, related to their strong antioxidant activity.

Seeds were last available in June Phenolic content of L. 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 ].

For example, in a study performed by Ali-Ahmmad et al. To glaucescems the main phenolic compounds of the extracts of L. Nevertheless, the structural features of these phenolics are important too such as those described above as enhancer of the antioxidant activity of the L. The fact that S. Antibacterial activity of L. Antibacterial activity of extracts was evaluated by the modified microdilution broth method [ 24 ].

This page was last edited on 15 Februaryat In this sense, the study of the effect that the different seasons have on the chemical composition and biological properties of plants can contribute to their optimal use in the folk medicine [ 1819 ]. Although litseaa in comparison to the effect of chloramphenicol, which was used as positive control, the L.
