A Systematic Review for Anti-Inflammatory Property of Clusiaceae Family: A Preclinical Approach
Background. Clusiaceae family (sensu lato) is extensively used in ethnomedicine for treating a number of disease conditions which include cancer, inflammation, and infection. The aim of this review is to report the pharmacological potential of plants of Clusiaceae family with the anti-inflammatory activity in animal experiments. Methods. A systematic review about experiments investigating anti-inflammatory activity of Clusiaceae family was carried out by searching bibliographic databases such as Medline, Scopus and Embase. In this update, the search terms were âanti-inflammatory agents,â âClusiaceae,â and âanimals, laboratory.â Results. A total of 255 publications with plants this family were identified. From the initial 255 studies, a total of 21 studies were selected for the final analysis. Studies with genera Allanblackia, Clusia, Garcinia or Rheedia, and Hypericum showed significant anti-inflammatory activity. The findings include a decrease of total leukocytes, a number of neutrophils, total protein concentration, granuloma formation, and paw or ear edema formation. Other interesting findings included decreased of the MPO activity, and inflammatory mediators such as NF-ÎșB and iNOS expression, PGE2 and Il-1ÎČ levels and a decrease in chronic inflammation. Conclusion. The data reported suggests the anti-inflammatory effect potential of Clusiaceae family in animal experiments
Characterization of teas from Lippia gracilis schauer genotypes by HPLC-DAD chromatographic profile combined with chemometric analyses
In order to evaluate the effects of environmental factors on the content
of secondary metabolites, the chemical profiles of infusions from leaves of seven genotypes of Lippia gracilis Schauer, sourced from
two locations (Sergipe and Bahia state) and collected during different seasons: summer (with and without irrigation) and winter, were
determined by HPLC-DAD. The fingerprint chromatograms were analyzed by PCA to evaluate similarities and differences among
the samples. Results revealed differences among genotypes collected and cultivated under the same conditions, suggesting that three
genotypes have greater resistance to drought conditions
Ent-kaurane diterpenoids and other constituents from the stem of Xylopia laevigata (Annonaceae)
Phytochemical investigation of the hexane extract from the stem of Xylopia laevigata led to the isolation of the ent-kaurane diterpenoids, ent-kaur-16-en-19-oic acid, 4-epi-kaurenic acid, ent-16ÎČ-hydroxy-17-acetoxy-kauran-19-al, ent-3ÎČ-hydroxy-kaur-16-en-19-oic acid, and ent-16ÎČ,17-dihydroxy-kauran-19-oic acid, as well as spathulenol and a mixture of ÎČ-sitosterol, stigmasterol and campesterol. The identification of the compounds was performed on the basis of spectrometric methods including GC-MS, IR, and 1D and 2D NMR. Potent larvicidal activity against Aedes aegypti larvae with LC50 of 62.7 ”g mL-1 was found for ent-3ÎČ-hydroxy-kaur-16-en-19-oic acid. This compound also showed significant antifungal activity against Candida glabrata and Candida dubliniensis with MIC values of 62.5 ”g mL-1
Chemical constituents of methanolic extracts of Jatropha curcas L and effects on Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae)
The biological activity of seven extracts from leaves of different Jatropha curcas L (Euphorbiaceae) accessions was evaluated on Spodoptera frugiperda. Methanol extracts were incorporated into an artificial diet and offered to the larval stage of S. frugiperda. The parameters evaluated were length of larval and pupal stages, mortality of larval and total cycle stage, and weight of pupae. The extracts of the EMB accessions showed the best result for larval mortality at 60.00 and 56.67%, compared with the control, respectively. Hexane partition of the methanol extract of the leaves of PM-14 accessions allowed the identification of phytosterols, phytol and n-alkanols
Chemical composition, antinociceptive, anti-inflammatory and redox properties in vitro of the essential oil from Remirea maritima Aubl. (Cyperaceae)
Methods:
The essential oil from the roots and rhizomes of RMO were obtained by hydrodistillation using a Clevenger apparatus, and analyzed by gas chromatography/mass spectrometry (GC/MS). Here, we evaluated free radical scavenging activities and antioxidant potential of RMO using in vitro assays for scavenging activity against hydroxyl radicals, hydrogen peroxide, superoxide radicals, and nitric oxide. The total reactive antioxidant potential (TRAP) and total antioxidant reactivity (TAR) indexes and in vitro lipoperoxidation were also evaluated. The ability of RMO to prevent lipid peroxidation was measured by quantifying thiobarbituric acid-reactive substances (TBARS). NO radical generated at physiological pH was found to be inhibited by RMO, that showed scavenging effect upon SNP-induced NO production at all concentrations. Antinociceptive and anti-inflammatory properties were evaluated by acetic acid writhing reflex, Formalin-induced nociception and Carrageenan-induced edema test.
- Results:
The majors compounds identified was remirol (43.2%), cyperene (13.8%), iso-evodionol (5.8%), cyperotundone (5.7%), caryophyllene oxide (4.9%), and rotundene (4.6%). At the TRAP assay, RMO concentration of 1 mg.mLâ1 showed anti-oxidant effects and at concentration of 1 and 10 ng.mLâ1 RMO showed pro-oxidant effect. RMO at 1 mg.mLâ1 also showed significant anti-oxidant capacity in TAR measurement. Concentrations of RMO from 1 ng.mLâ1 to 100 ÎŒg.mLâ1 enhanced the AAPH-induced lipoperoxidation. RMO reduced deoxyribose oxidative damage, induced by the Fenton reaction induction system, at concentrations from 1 ng.mLâ1 to 100 ÎŒg.mLâ1. We observed that RMO caused a significant increase in rate of adrenaline auto-oxidation. On the other hand RMO did not present any scavenging effect in H2O2 formation in vitro. The results of this study revealed that RMO has both peripheral and central analgesic properties. The RMO, all doses, orally (p.o.) administered significantly inhibited (pâ<â0.05, pâ<â0.01 and pâ<â0.001) the acetic acid-induced writhings and two phases of formalin-induced nociception in mice.
- Conclusion:
The RMO demonstrated antioxidant and analgesic profile which may be related to the composition of the oil
