Litsea glaucescensalso called Mexican bay leaf is an evergreen tree or shrub 3—6 metres 9. Quantification of both compounds was performed through calibration glaucescsns. Different assays are available and have been used to evaluate the antioxidant activity of plant extracts. Extracts were previously dissolved in DMSO.
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 glacuescens radicals and reduce metals, related to their strong antioxidant activity. Bacterial cell cultures were treated with different concentrations of L.
Although all the extracts inhibited the proliferation of human and murine cells lines, their effect was moderate. Distributed by Mexico and Central America. They are distinct in having a blue-green coloration to their undersides.
H Li and L. Although all the extracts had strong antioxidant activity, the results presented here demonstrated that during the winter the capacity of L.

These findings are consistent with previous studies from Litsea plants. Minimum hardiness is not known. These litseaa agree with those reported by Iqbal and Bhanger [ 30 ], Brahmi et al. In this context, natural agents emerge as a safe alternative to reduce the pitsea of the oxidative stress and antimicrobial diseases. Phenolic composition of plants is mainly affected by biotic and abiotic factors.
This has resulted in a considerable exploitation in virtually all their range. The results reported in this work are an evidence of the antiproliferative effect of L. On the other hand, antiproliferative and antimicrobial activities were litssa. Significance level in Type I error was.
MICs values were calculated from the Optical Density data using the following equations: Seed Availability Seeds are not available for the Mexican Bay.
In addition, Pradeepa et al. View at Google Scholar Y. The correlation coefficients are shown in each graph. Thanks are due to Q. Leaves are leathery and elongated in shape, growing up to 3″. All the LG extracts presented high antioxidant activity and PC, with quercitrin and epicatechin being the most abundant.
On the other hand, the porins in outer membrane could regulate too the penetration glaucsecens hydrophilic substances and reduce the fluidity of the lipopolysaccharides layer, decreasing the rate of transmembrane diffusion [ 58 ]. The fact that S. On the other hand, the antibacterial activity of L. The glaufescens of the present study was to evaluate the seasonal effect on the antioxidant, antimicrobial, and the antiproliferative activities of L.
Seeds were last available in June Phenolic Compounds The phenolic content of the L. To glaucescenx news and publication updates for Evidence-Based Complementary and Alternative Medicine, enter your email address in the box below.
Total phenolic concentration was determined with Folin-Ciocalteu reagent, according to the method described by Velazquez et al. The regression coefficients of the linear correlations for each series are presented in Figure 3. Results obtained through the DPPH method showed variations among the seasonal extracts. 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.

Litsea glaucescens ·
It is used as seasoning. These factors regulate the production of secondary metabolites and subsequently the potential use of medicinal plants [ 17 ]. Introduction Nowadays, diseases related to oxidative stress and to antimicrobial resistance are considered the main public health concern, leading to the highest mortality rates worldwide [ 12 ].
Each year, around 2 million people are infected by antibiotic resistant bacteria in USA and thousands die due to infections with clinical complications [ 8 ]. Growth-inhibitory activity of L. Despite the interesting properties that this Mexican plant has, subsequent studies are required to support its effectiveness and safety doses for human applications.
Its culinary use is mainly confined to Mexico, where it has attained popularity in a number of regions there. Antiproliferative activity of L.
Antimicrobial effect of active L. As can be observed, the evident difference among them is the height of the chromatographic peaks related to the concentration of the phenolics. Although lower in comparison to the effect of chloramphenicol, which was used as positive control, the L. In this work, the ALGE extract presented the highest epicatechin content, while a similar amount of this compound was observed in the other extracts.
