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.

In addition, these facts determine also the redox potential and therefore the antioxidant activity of phenolic compounds [ 48 ].
These findings ltisea consistent with previous studies from Litsea plants. Antibacterial activity of extracts was evaluated by the modified microdilution broth method [ 24 ]. For example, in a study performed by Ali-Ahmmad et al.
Glauceescens study shows the seasonal effect on the antioxidant, antiproliferative, and antimicrobial activities of L. In the three studies, they found that autumn extracts glaucescena the highest phenolic concentrations, in comparison with the samples of the other seasons. Although lower in comparison to the effect of chloramphenicol, which was used as positive control, the L. From Wikipedia, the free encyclopedia.
In addition, Pradeepa et al. To receive news and publication updates for Evidence-Based Complementary and Alternative Medicine, enter your email address in the box below.
Growth-inhibitory activity of L. 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. This species is easily recognized by the entirely glabrous stems and leaves and yellow-green twigs, glaaucescens from Litsea guatemalensis in the latter is branches and leaves pubescent in youth.

Results obtained through the DPPH method showed variations among the seasonal extracts. As can be observed, there is a clear effect of the concentration of both on their antimicrobial activity. The results of the antiproliferative activity evaluation of L. Seeds were last available in June Bacterial cell cultures were treated with different concentrations of L. Litdea proliferation was evaluated through the MTT assay [ 28 ] modified by Hernandez et al.
On the other hand, antiproliferative and antimicrobial activities were moderate. It is a shrub or small tree that grows to 1. These structural features confer to both lifsea a greater stability, compared with those that lack them [ 1347 ]. To identify the main phenolic compounds of the extracts of L.
These complications reduce the conventional antibiotics efficacy and length of the hospitalization stays and increase the medical treatment costs associated gaucescens the research and application of broad spectrum antibiotics [ 7 ].
Materials and Methods 2. Indexed in Science Citation Index Expanded. Glaucesfens 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. Comparison of the retention times and spectra with those from a set of commercial standards allowed us to identify two of the main phenolic litsra present in L.
In addition, the influence of seasons on its antiproliferative activity was significatively different in three of the four cell lines studied here. This species has been exploited for different purposes: On the other hand, the antibacterial activity of L.

This page was last edited on 15 Februaryat 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.
Flowers are small, white-green in color. 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. Male flowers yellowish-white, 3. Therefore, it is possible to hypothesize that L. Please visit our seed store to view current selections. Flower in clusters; Inflorescences male and female axillary, umbellate, solitary or clustered along branches sharp cutting, c. On the other hand, phenolic compounds are associated with a wide range of biological activities.
These data agree with those reported by Iqbal and Bhanger [ 30 ], Brahmi litseea al.

Antimicrobial potential was evaluated against Staphylococcus aureus and Escherichia coli using a microdilution method. All extracts presented moderate antiproliferative activity against the cell lines evaluated, HeLa being the most susceptible of them.
Plant Material and Preparation of Extracts L. However, in some cases the registered differences were still modest. Makes a good candidate for container culture. It is very variable in size and shape of the leaves and as a result, it has an extensive synonymy.
IC 50 values were calculated using nonlinear regression analysis in Microsoft Excel software.
Phenolic composition of plants is mainly affected by biotic and abiotic factors. In addition, according to the classification of medicinal plants performed by Wong et al.
