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.

On the other hand, antiproliferative and antimicrobial activities were moderate. In this sense, the study of the effect that the glaucsscens seasons have on the chemical composition and biological glaucrscens of plants can contribute to their gkaucescens use in the folk medicine [ 1819 ].

As can be observed in Table 3HeLa was the more sensitive cell line to the L. On the other hand, Cushnie and Lamb [ 6667 ] have concluded that phenolic compounds have different mechanism of action as antimicrobial, such as inhibitors of nucleic acid synthesis, of the energy metabolism, or of the cytoplasmic membrane function of the microorganisms.

Even more, these last three values are the highest of Table 3 and constitute an evidence of the selectiveness of the L. Evidence-Based Complementary and Alternative Medicine. For example, in a study performed by Herrera-Carrera et al.

In this regard, it has been proposed by other authors that the outer membrane of Glxucescens bacteria, constituted by phospholipid and lipopolysaccharides, provides resistance to antimicrobial treatments [ 57 ].

They are distinct in having a blue-green coloration to their undersides.

Minimum hardiness is not known. It is well known that the antioxidant activity of natural products is strongly related to the content of phenolic compounds that they have, and the results obtained in this work agree with that fact.

The correlation coefficients are shown in each graph. These findings are consistent with previous studies from Litsea glaucfscens.

Collected leaves were washed and dried.

Phenolic content of L. Free-radical scavenging activity was measured following the modified method reported by Usia et al.

Therefore, it is possible to hypothesize that L. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. Identification of phenolic compounds was carried out by comparison of the retention times and spectra with those of authentic standards. Liitsea acid phenethyl ester CAPE was used as a positive control in the antiproliferative assay.

Nowadays, diseases related to oxidative stress and to antimicrobial resistance are flaucescens the main public health concern, leading to the highest mortality rates worldwide [ 12 ]. In addition, these compounds had shown a broad spectrum of biological activities, demonstrating the potential of plants as alternative drugs [ 1314 ].

Control bacterial cultures were incubated with DMSO 0. All extracts presented moderate antiproliferative activity against the cell lines evaluated, HeLa being the most susceptible of them. This study shows the seasonal effect on the antioxidant, antiproliferative, and antimicrobial activities of L. Seeds were last available in June Retrieved from ” https: On the other hand, the antibacterial activity of L. Nevertheless, it was not able to inhibit the growth of E.

The regression coefficients of the linear correlations for each series are presented in Figure 3. 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 ]. Flowers are small, white-green in color. Many parts of the plant contain essential oils that are reminiscent of the bay leaf. From Wikipedia, the free encyclopedia.

Although all the extracts inhibited the proliferation of human and murine cells lines, their effect was moderate. On the other 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 addition, the influence of seasons on its antiproliferative activity was significatively different in three of the four cell lines studied here. 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.

These findings provide new information about the seasonal effect on the PC and biological properties of LG extracts.
