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, . Thirty-one compounds are identified in the essential oil of Mexican bay (Litsea glaucescens var. glaucescens), which is dominated by ± % 1.

Lucila Rascon for her technical assistance with the cell culture and the antiproliferative assays.
These findings are consistent with previous studies from Litsea plants. Different assays are available and have been used to evaluate the antioxidant activity of plant extracts. The bark is brown, thick trunk. Ltsea bacterial cultures were incubated with DMSO 0. Concentration of major phenolic compounds identified in L.
According to those studies, the Gram-positive bacteria would have lesser resistance to antimicrobial treatments. IC 50 values were calculated throughout linear regression analysis using Microsoft Excel software. It is used as seasoning. It is in danger of extinction,  [ citation needed ] because it has been used extensively for various uses, medicinal and culinary purposes even religious during the celebration of Palm Sunday. As glaucdscens hypothesized, it seems that phenolic compounds were the main compounds responsible for the antioxidant activity of the four L.

The species is one of the most important non-wood trees of Mexico. In addition, Pradeepa et al. The results reported in this work are an evidence of the antiproliferative effect of L.
The corresponding values are shown in Table 2 ; and as can be observed there are significant differences among them.
Litsea glaucescens – Wikipedia
In the three studies, they found that autumn extracts presented the highest phenolic concentrations, in comparison with the samples of the other seasons. Leaves are leathery and elongated in shape, growing up to 3″.
Litsea glaucescens is quite common in temperate forests of Mexico, coming to meet [ clarification needed ] in the areas of contact with other vegetation types of affinity rather warm.
Antimicrobial potential was evaluated against Staphylococcus aureus and Escherichia coli using a microdilution method. Subscribe to Table of Contents Alerts. There are supposedly a handful of varieties or variants of this species, though minimal attention seems to be given to propagating select types. On the other hand, phenolic compounds are associated with a wide range of biological activities.

These structural features confer to both compounds a greater stability, compared with those that lack them [ 1347 ].
Distributed by Mexico and Central America. As can be observed, positive slopes were obtained in all the cases. These findings provide new information about the seasonal effect on the PC and biological properties of LG extracts.
Therefore, the cellular damage would eventually result in the development of chronic diseases like cancer, atherosclerosis, rheumatoid arthritis, diabetes, chronic inflammation, and cardiovascular ills, among others [ 4 ]. 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 ].
From the results reported here, the antioxidant activity was the strongest one and clearly dependent on the season. The chromatographic profiles of the four seasonal extracts are shown in Figure 2.
Similarly, Areekul et al. For example, in a study performed by Herrera-Carrera et al. The capacity of L.
Evidence-Based Complementary and Alternative Medicine. These facts suggest that they have the potential to stabilize biological radicals and to inhibit the generation of reactive oxygen species, which could contribute to reducing the oxidative stress caused by them and therefore to avoiding the DNA damage. Its culinary use is mainly confined to Mexico, where it has attained popularity in a number of regions there. Abstract This study shows the seasonal effect on the antioxidant, antiproliferative, and antimicrobial activities of L.
These activities are mainly related to the presence of different compounds such as terpenes and phenolic compounds [ 2223 ]. In addition, according to the classification of medicinal plants performed by Wong et al. View at Google Scholar Y.
Flowers are small, white-green in color. Its leaves have been traditionally used as food seasoning, as well as remedy in folk medicine against central nervous system illness, depression, colic, pain, vomit, and diarrhea [ 21 ]. F6 murine B-cell lymphoma was provided by Dr.
They are distinct in having a blue-green coloration to their undersides.
The first of them increased slightly during the autumn and summer, which is related to the major concentration of phenolic compounds produced by the plant as response to the environmental conditions. In addition, these facts determine also the redox potential and therefore the antioxidant activity of phenolic compounds [ 48 ].
All extracts presented moderate antiproliferative activity against the cell lines evaluated, HeLa being the most glaucescebs of them. Quercitrin was the most abundant phenolic compound in the four extracts, and to the best of our knowledge, this is the first time that it is reported as a component of L.
Nowadays, diseases related to oxidative stress and to antimicrobial resistance are considered the main public health concern, leading to pitsea highest mortality rates worldwide [ 12 ].
Uses The plant is used as a spice, notably as a substitute for bay Laurus nobilis. Plant Material and Preparation of Extracts L. Although all the extracts had strong antioxidant activity, the results presented here demonstrated that during the winter the capacity of L.
