Background. Byrsonima is a promising neotropical genus, rich in flavonoids and triterpenes, with several proven pharmacological properties. Nevertheless, Byrsonima duckeana W. R. Anderson is an Amazonian species almost not studied. Objective. To assess the antioxidant, anti-inflammatory, and analgesic activities of Byrsonima duckeana leaves. Materials and Methods. We analyzed an ethanol extract and its fractions for polyphenol content and UHPLC-MS/MS, phosphomolybdenum, DPPH, TBARS antioxidant tests, formalin-induced pain, carrageenan-induced peritonitis, acetic acid-induced abdominal writhings, and hot plate assays. Results. All the samples showed high polyphenol content and antioxidant capacity in the phosphomolybdenum, DPPH, and TBARS tests. We identified ethyl gallate, quinic acid, gallic acid, catechin, epicatechin, quercetrin, and quercetin in the samples. B. duckeana was able to reduce leukocyte migration in the carrageenan-induced peritonitis by 43% and the licking time in the formalin test by 57%. In the acetic acid-induced writhing test, the chloroform (FCL) and ethyl acetate (FEA) fractions were the most active samples. FEA was selected for the hot plate test, where all the dosages tested (5, 50, and 200 mg·kg−1) showed significant analgesic activity. Conclusion. B. duckeana has interesting analgesic and antioxidant activities, due to its high phenolic content, especially phenolic acids.

Objective: The objective of the study was to evaluate the anti-inflammatory and antinociceptive effects of Artemisia afra.Methods: Animals were randomly divided into five groups of six animals each and administered with normal saline (2 ml/kg), indomethacin (10 mg/ kg), and A. afra at doses of 100, 200, and 400 mg/kg, respectively. For the anti-inflammatory activity, carrageenan-induced paw edema was used while the hot plate and acetic acid induced-writhing tests were used to assess the antinociceptive activity.Results: Pretreatment with A. afra at a dose of 100 mg/kg did not show any significant biological effects (p>0.05) for any of the three tests, when compared against saline-treated control group. At a dose of 200 mg/kg, A. afra demonstrated significant effects (p<0.01), during the 5th h reducing carrageenan-induced paw edema by 12%. The highest dose (400 mg/kg) of A. afra demonstrated more potent effects by decreasing the carrageenan-induced paw swelling (p<0.001–0.05) during the 3rd, 4th, and 5th h, by up to 38% when compared against saline-treated control group. Both the 200 and 400 mg/kg, A. afra doses achieved a significant increase (p<0.05) in reaction time in the hot plate test. In the acetic acid-induced writhing test, pretreatment with A. afra (400 mg/kg) significantly reduced pain by 39% (p<0.01) by comparison with the saline control.Conclusion: Experimental data demonstrated that aqueous extract of A. afra possesses anti-inflammatory and antinociceptive properties in experimental acute inflammation and pain. These findings support the usage of A. afra in managing inflammation and pain in traditional practice.

The present study was aimed to evaluate the analgesic and anti-inflammatory properties ofCastanospermum australeand to profile phytochemicals by GC-MS. The ethanolic extracts were prepared by successive solvent extraction using Soxhlet apparatus. The analgesic activity was analyzed by hot plate method and acetic acid-induced writhing test whereas anti-inflammatory study was done by carrageenan induced paw oedema model. The acute toxicity study revealed that ethanol extracts of leaf and bark ofC. australewere safe even at a higher dose of 2000 mg/kg whereas ethanol extract of seed was toxic at the same dose. In both hot plate method (5.85 s) and acetic acid-induced writhing test (57%), the leaf ethanol extract exhibited significant analgesic activity (P<0.001) at a dose of 400 mg/kg. The anti-inflammatory activity of leaf extract was exhibited by the reduction in paw linear diameter by 64.76% at 400 mg/kg in carrageenan induced paw oedema. The GC-MS analysis of the ethanol extract of leaf revealed sixteen major compounds of which 1,7-dimethyl-4,10-dioxa-1,7-diazacyclododecane, (+)-N-methylephedrine, and permethylspermine were found to be pharmaceutically and the most important. These findings justify thatC. australecan be a valuable natural analgesic and anti-inflammatory source which seemed to provide potential phytotherapeutics against various ailments.

Abstract Background To investigate the antinociceptive and anti-inflammatory activities of aqueous extract of a blended mixture of dried leaves of Ocimum gratissimum and Psidium guajava, a traditional analgesic drug polyherbal (TADP) used as a remedy for pain-related conditions. Methods Antinociceptive activity of TADP (100, 200 and 400 mg/kg) was evaluated in the hot plate test and acetic acid-induced nociception in mice while the anti-inflammatory was evaluated in carrageenan-induced paw oedema in rats. Levels of nitrite, myeloperoxidase, glutathione and malondialdehyde were assayed in carrageenan-induced paw tissue. Results TADP (200 and 400 mg/kg) significantly prolong the latency time in the hot-plate test. TADP (100–400 mg/kg) produced a dose-dependent significant inhibition of the acetic-acid induced abdominal constriction. The antinociceptive activity of TADP in the presence of naloxone and atropine was not reversed whereas yohimbine and glibenclamide significantly reversed it. TADP (100, 200 and 400 mg/kg) significantly reduced the swelling in the carrageenan-induced oedema model and also produced a reduction in the nitrite and myeloperoxidase level. TADP (400 mg/kg) significantly reduced malondialdehyde concentration and increase glutathione level in the carrageenan-induced rat paw. TADP significantly decrease the number of cellular infiltrates in the histopathological assessment. Conclusion These results indicate that polyherbal product containing blended leaves of Ocimum gratissimum and Psidium guajava possess antinociceptive and anti-inflammatory properties, hence represents a promising alternative remedy in inflammation-induced pain.

Borneol, a bicyclic monoterpene, has been evaluated for antinociceptive and anti-inflammatory activities. Antinociceptive and anti-inflammatory activities were studied by measuring nociception by acetic acid, formalin, hot plate, and grip strength tests, while inflammation was prompted by carrageenan-induced peritonitis. The rotarod test was used to evaluate motor coordination. Borneol produced a significant (P<0.01) reduction of the nociceptive behavior at the early and late phases of paw licking and reduced the writhing reflex in mice (formalin and writhing tests, resp.). When the hot plate test was conducted, borneol (in higher dose) produced an inhibition (P<0.05) of the nociceptive behavior. Such results were unlikely to be provoked by motor abnormality. Additionally, borneol-treated mice reduced the carrageenan-induced leukocytes migration to the peritoneal cavity. Together, our results suggest that borneol possess significant central and peripheral antinociceptive activity; it has also anti-inflammatory activity. In addition, borneol did not impair motor coordination.

Haloxylon Salicornicum

AbstractThe medicinal plant Haloxylon salicornicum is utilized for therapeutic purposes. We previously reported the antioxidant potential of hexane fraction and methanol extracts of the same species. However, since these solvents could be clinically toxic, the current findings investigated the pharmacological effects of the water fraction. The pain relieving, antioxidant, anti-inflammatory, and antipyretic potential of H. salicornicum water extract (HEW) were studied at two concentrations (250 and 500 mg/kg) in rodents. The carrageenan stimulated rat paw edema assay was exercised to assess anti inflammatory potential in rats; yeast-stimulated hyperthermia was utilized to test antipyretic activity in mice; analgesic properties were assessed based on acetic acid-induced writhing, tail flicking, and hot-plate test; and antioxidant potential was examined with the 2,2-diphenyl-1-picrylhydrazyl assay. We found that 500 mg/kg HEW inhibited edema by 44.03%. Yeast-induced hyperthermia in mice was reduced by 250 and 500 mg/kg HEW after 30, 60, and 120 min with significant level of (P < 0.001) compared to rectal temperature of yeast administered group. The high dose of HEW (500 mg/kg) improved the reaction time of mice in the hot-plate test from 6.66 ± 0.33 to 11.33 ± 0.49 s after 120 min. In the acetic acid-stimulated writhing test, 250 and 500 mg/kg HEW decreased writhing by 32.71% and 51.40%, respectively, after 20 min. HEW also showed antioxidant effects. These results demonstrate that HEW is bioactive and has therapeutic potential for treating a variety of ailments.

We investigated the antinociceptive and anti-inflammatory activities of the crude ethanolic extract (CEE), its fractions, and the flavonoid isorhamnetin fromAspidosperma tomentosumusing models of nociception and inflammation in mice. In the writhing test, the CEE and its fractions (except for soluble phase, CHCl3100% and EtAcO 100%) at 100 mg/kg p.o. induced antinociceptive activity. Isorhamnetin (100 μmol/kg, p.o.) was also active. In the hot plate test, only the treatment with the fractions Hex : CHCl350%, CHCl3100%, and CHCl3 : MeOH 5% (100 mg/kg, p.o.) increased the latency time, reversed by the opioid antagonist naloxone. Fractions that were active in the hot plate test did not show catalepsy condition. It was observed that CEE, all fractions, and isorhamnetin reduced the formalin effects in the neurogenic phase. In the inflammatory phase, only CEE, isorhamnetin, and CHCl3100% and CHCl3 : MeOH 5% fractions were active. CEE and all fractions, except for CHCl3 : MeOH 10% fraction, isorhamnetin, and soluble fraction were able to produce an antioedematogenic activity in the ear capsaicin-induced edema test. In the thioglycolate-induced peritonitis, only EtAcO 100% fraction was not active. The results demonstrate thatA. tomentosumhas antinociceptive and anti-inflammatory activities in animal models.
