Abstract The genus Galphimia is widely distributed in Mexico, and is represented by 22 species, including medicinal species. The sedative and anti-inflammatory effects of galphimines produced by the species Galphimia glauca have been documented. Formerly, molecular studies using DNA barcodes demonstrated that nine populations botanically classified as Galphimia glauca belong to four different species of the genus Galphimia, and that only one exhibited the sedative properties; however, all the collected species showed anti-inflammatory activity. Other bioactive compounds like quercetin, galphins, galphimidins and glaucacetalins have been identified from methanolic extracts of plants botanically classified as Galphimia glauca. The aim of this work was to determine the anti-inflammatory activity of methanolic extracts of nine collected Galphimia spp. populations grown in Mexico. The possible modes of action were analyzed by evaluating the inhibition of LPS-induced inflammation processes both in vitro and in vivo. The nine populations were evaluated by an in vitro model using RAW 264.7 murine macrophage cells, and two populations (a galphimine-producing and a non-galphimine-producing population) were selected for the in vivo experiments of systemic inflammation and neuroinflammation in mice. Results suggest that an anti-inflammatory in vitro effect was present in all the studied populations, evidenced by the inhibition of nitrite production. An inhibitory systemic inflammation in mice was exerted by the two analyzed populations. In the neuroinflammation model, the anti-inflammatory effect was demonstrated in methanolic extract of the non-galphimine-producing population. For the populations of Galphimia spp. studied herein, the anti-inflammatory effect could not be correlated to the presence of galphimines.

Objective: The aim of this research was to assess the in vitro anti-inflammatory activity and cytotoxicity of the methanolic extract and total alkaloid extract obtained from leaves and bulbs of Crinum x amabile (CA) growing in Ecuador.Methods: Methanolic extracts of dry powered leaves and bulbs of CA obtained by cold maceration method were subjected to preliminary phytochemical screening. Total alkaloid extracts of leaves and bulbs of CA were obtained by conventional extraction of alkaloids base with an organic solvent. Furthermore, the anti-inflammatory activity and cytotoxicity of the four extracts were investigated by in vitro isolated neutrophils model using stable tetrazolium salt (WST-1).Results: Phytochemical analysis of methanolic extracts revealed the major classes of phytochemicals such as alkaloids, flavonoids, tannins, triterpenes, and steroids, but no proteins or saponins could be detected on leaves extract. Extracts obtained from bulbs both methanolic and total alkaloids of CA show an interesting anti-inflammatory activity, although it was not significant compared to the standard anti-inflammatory drug, aspirin. Cytotoxicity of bulb alkaloid extract was lower compared with all of the other extracts.Conclusion: Based on the results of this research, it could be concluded that CA is a very interesting source of natural anti-inflammatory compounds (especially alkaloids) which could be used to prevent many chronic disorders. Further, phytochemical studies are necessary to identify the chemical compounds responsible for the significant anti-inflammatory activity showed.

Herbal medicines and their preparations have been widely used from the thousands of years in developing and developed countries in the primary health care of society and community. They have great demand due its safety, efficacy with minimum side or adverse effects. Commiphora caudata. It’s known as konda mava in kannada, ikkata in Sanskrit and hill mango in English. It’s widely used in the management of various disorders. Hence the identification of bioactive fractions from various parts of selected medicinal plant is important. In the present research work an attempt has been made to screen and assess the antibacterial, antifungal and anti-inflammatory activities of Commiphora caudata barks. The barks of selected plant material were collected, authenticated, powdered and subjected for extraction procedure. The extracts were screened for presence of various phytoconstituents. The antibacterial activity of chloroform and methanolic extracts were performed against various strains of bacteria and fungi. The extracts also were investigated for its in-vivo anti-inflammatory activity. The result of investigation concludes that chloroform and methanolic extract of plant were potential to inhibit the growth of selected strains of microorganism and also produced potential anti-inflammatory effect.

The study was aimed to evaluate the analgesic and anti-inflammatory activity (by both in-vitro and in-vivo) of both chloroform and methanol root extracts of Andrographis serpyllifolia (Rottl. Ex Vahl.) Wt. Methods used for the studies were In-vitro 5-Lipoxygenase inhibition assay and In-vivo measurement of rat paw edema and ear edema in rats, acetic acid induced writhing response and hot plate method in albino mice. Chloroform and methanolic extracts of A. serpyllifolia root have shown moderate potency in inhibiting 5-LOX and shown significant anti-inflammatory activity. Despite the IC50 values are little higher, anti-inflammatory efficacy of these extracts possibly due to other mechanisms apart of 5-LOX inhibition. However, In-vivo anti-inflammatory studies revealed that A. serpyllifolia methanolic extract has shown higher degree of efficacy when compared to the chloroform extract. In terms of analgesic activity in writhing test, methanolic extract has shown more efficacy than chloroform extract. Hence, it is important to isolate the active principles for further testing the anti-inflammatory efficacy.DOI: http://dx.doi.org/10.3329/icpj.v1i8.11250 International Current Pharmaceutical Journal 2012, 1(8): 199-204

Vitex mollisis used in traditional Mexican medicine for the treatment of some ailments. However, there are no studies on what happens to the anti-inflammatory activity or antioxidant properties and total phenolic content of leaves and stem extracts ofVitex mollisduring the digestion process; hence, this is the aim of this work. Methanolic, acetonic, and hexanic extracts were obtained from both parts of the plant. Extract yields and anti-inflammatory activity (elastase inhibition) were measured. Additionally, changes in antioxidant activity (DPPH and ABTS) and total phenols content of plant extracts before and afterin vitrodigestion were determined. The highest elastase inhibition to prevent inflammation was presented by hexanic extracts (leaf = 94.63% and stem = 98.30%). On the other hand, the major extract yield (16.14%), antioxidant properties (ABTS = 98.51% and DPPH = 94.47% of inhibition), and total phenols (33.70 mg GAE/g of dried sample) were showed by leaf methanolic extract. Finally, leaf and stem methanolic extracts presented an antioxidant activity increase of 35.25% and 27.22%, respectively, in comparison to their initial values afterin vitrodigestion process. All samples showed a decrease in total phenols at the end of the digestion. These results could be the basis to search for new therapeutic agents fromVitex mollis.
