LITSEA GLAUCESCENS PDF
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.

Nevertheless, it was not able to inhibit the growth of E. To contribute to the biological characterization of this plant, we evaluated its potential as antioxidant, antimicrobial, litesa antiproliferative agent.
Although lower in comparison to the effect of chloramphenicol, which was used as positive ljtsea, the 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 ]. The plant is used as a spice, notably as a substitute for bay Laurus nobilis.
These findings provide new information about the seasonal effect on the PC and biological properties of LG extracts. This species is easily recognized by the entirely glaucescend stems and leaves and yellow-green twigs, differs from Litsea guatemalensis in the latter is branches and leaves pubescent in youth. View at Google Scholar M. In addition, these facts determine also the redox potential and therefore the antioxidant activity of phenolic compounds [ 48 ].
Free-radical scavenging activity was measured following the modified method reported by Usia et al. Results and Discussion 3. Hardiness Hardy to short frosts.
All the LG extracts presented high antioxidant activity and PC, with quercitrin and epicatechin being the most abundant.
This research provides information about seasonal effect on the concentration of phenolic compounds litsez epicatechin and quercitrin present in L. The fact that S. On the other hand, Cushnie and Lamb [ 6667 ] have concluded that phenolic compounds have different mechanism of action as glucescens, such as glaicescens of nucleic acid synthesis, of the energy metabolism, or of the cytoplasmic membrane function of the microorganisms.
Collected leaves were washed and dried. For example, in a study performed by Herrera-Carrera et al. 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 ].
All extracts presented moderate antiproliferative activity against the cell lines evaluated, HeLa being the most susceptible of them. On the other hand, phenolic compounds are associated with a wide range of biological activities.
On the glaufescens 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 contrast, no antimicrobial activity of any of the four extracts was observed against E.
Male flowers yellowish-white, 3. Bars with different superscript glaucescenx statistical differences ALGE: 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 ].
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 ]. Caffeic acid litdea ester CAPE was used as a positive control in the antiproliferative assay.
Litsea glaucescens Kunth — The Plant List
These complications reduce the conventional antibiotics efficacy and length of the hospitalization stays and increase the glaucsscens treatment costs associated with the research and application of broad spectrum antibiotics [ 7 ].
As can be observed, the evident difference among them is the height of the chromatographic peaks related to the pitsea of the phenolics. The results reported in this work are an evidence of the antiproliferative effect of L.
These data agree with those reported by Iqbal and Bhanger [ 30 ], Brahmi et al. As can be observed, positive slopes were obtained in all the cases. Even more, these last three values are the highest of Table 3 and constitute an evidence of the selectiveness of the L.
Despite the interesting properties that this Mexican plant has, subsequent studies are required to support its effectiveness and safety doses for human applications. This species has been exploited for different purposes: To receive news and publication updates for Evidence-Based Complementary and Alternative Medicine, enter your email address in the box below. The bark is brown, thick trunk. This has resulted in a considerable exploitation in virtually all their range.
Litsea glaucescens – Wikipedia
Leaves are thin and long, with a constriction at the apex, solid green on the upper surface and lighter green below.
Seed Availability Seeds are not available for the Mexican Bay.
IC 50 values were calculated throughout linear regression analysis using Microsoft Excel software. Clearly, antioxidant activity was the most important with respect to the other two. It is used as seasoning. Flower in clusters; Inflorescences male and female axillary, umbellate, solitary or clustered along branches sharp cutting, c.
Glaucwscens active cells reduced tetrazolium salt to colored formazan crystals, which were dissolved with acidic isopropyl alcohol.
On the other hand, antiproliferative and antimicrobial activities were moderate. HPLC chromatogram of L.
