Litsea glaucescens Kunth is a native plant from Central America and Mexico, mainly distributed in the states of Chiapas Nayarit and Veracruz. Thirty-one compounds are identified in the essential oil of Mexican bay (Litsea glaucescens scens), which is dominated by ± % 1,8-cineole, .

Makes a good candidate for container culture. Total Phenolic Content Total phenolic concentration was determined with Folin-Ciocalteu reagent, according to the method described by Velazquez et al.
These complications reduce the conventional antibiotics efficacy and length of the hospitalization stays and increase the medical treatment costs associated with the research and application of broad spectrum antibiotics [ 7 ]. Plant Material and Preparation of Extracts L. These structural features confer to lgaucescens compounds a greater stability, compared with those that lack them [ 1347 ].
Evidence-Based Complementary and Alternative Medicine
These gllaucescens agree with those reported by Iqbal and Bhanger [ 30 ], Brahmi et al. From the results reported here, the antioxidant activity was the strongest one and clearly dependent on the season.
Significance level in Type I error was. Total phenolic concentration was determined with Folin-Ciocalteu reagent, according to the method described by Velazquez et al. The results of the antiproliferative activity evaluation of L.
Antibacterial Assay Antibacterial activity of extracts was evaluated by the modified microdilution broth method [ 24 ]. View at Google Scholar K. Each year, around 2 million people are infected by antibiotic resistant bacteria in USA and thousands die due to infections with clinical complications [ 8 ].
The regression coefficients of the linear correlations for each series are presented in Figure 3. In the three studies, they found that autumn extracts presented the highest phenolic concentrations, in comparison with the samples of the other seasons. Quantification of both compounds was performed through calibration curves.

In addition, the increase in the enzymatic activity of PAL is related to an adaptation of the plant to stress [ 36 ].
Litsea glaucescens – Wikipedia
Oxidative stress has been explained in terms of the overproduction of intracellular reactive oxygen species, which may produce damage to biomolecules such as DNA, RNA, lipids, and proteins [ 3 ]. Bacterial cell cultures were treated with different concentrations of L. Results and Discussion 3. Stimulation, Extraction, and Utilizationpp.
Seed Availability Seeds are not available for the Mexican Bay.
On the other hand, ferric reducing power of the L. On the other hand, phenolic compounds are associated with a wide range of biological activities. This species is easily recognized by the entirely glabrous stems and leaves and yellow-green twigs, differs from Litsea guatemalensis glaucesecns the latter is branches and leaves pubescent in youth.
Therefore, it is possible to hypothesize that L. According to those studies, the Gram-positive bacteria would have lesser resistance to antimicrobial treatments.
In addition, the glaucedcens effect that the seasons had on the antioxidant capacity of L. This page was last edited on 15 Februaryat The corresponding values are shown in Table 2 ; and as can be observed there are significant differences among them. F6 murine B-cell lymphoma glaucescns provided by Dr.
The fact that S.
A Working list of All Plant Species”. In this context, natural agents emerge as lutsea safe alternative to reduce the problem of the oxidative stress and antimicrobial diseases. View at Google Scholar D.
Results of antibacterial activity of L. Metabolically active cells reduced tetrazolium salt to colored formazan crystals, which were dissolved with acidic isopropyl alcohol.
