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.

Analgesic, anti-inflammatory and anti-pyretic activities of n-hexane and aqueous ethanolic extracts of Malva neglecta in Swiss albino mice was evaluated. For each activity, the mice were divided into 4 groups: Group 1 served as control, Groups 2 and 3 were given n-hexane and aqueous ethanol extracts, respectively whereas Group 4 was treated with the standard drug. Analgesic activity was evaluated against acetic acid induced writhing, Eddy's hot plate method, and Formalin induced paw licking. Anti-inflammatory activity was evaluated by carrageenan-induced paw edema. The extracts were also examined for their anti-pyretic activities against yeast-induced pyrexia. Results showed that the n-hexane (p < 0.05) and aqueous ethanolic (p < 0.005) extracts of M. neglecta exhibited analgesic activity by reducing acetic acid-induced writhing, mean reaction time on hot plate model and formalin-induced paw licking in mice as compared to the control. The n-hexane extract (p < 0.05) as well as aqueous ethanolic (p < 0.005) extracts produced significant antiinflammatory activity as compared to the control. Both the n-hexane and aqueous ethanolic extracts revealed significant antipyretic activity (p < 0.005 and p < 0.05, respectively) in mice model. The results of the present study demonstrated that the n-hexane and aqueous ethanol extracts of M. neglecta possess analgesic, antiinflammatory and anti-pyretic activities. Bangladesh J.

Objective: The objective of the present work is to isolate, purify, and fractionate anthocyanin from selected Osbeckia species and also to compare the analgesic and anti-inflammatory potentiality using animal models.Methods: Methodologies include extraction of anthocyanin from the in vitro callus culture of Osbeckia aspera and Osbeckia reticulata, purification using amberlite column chromatography, and fractionation by liquid chromatography-tandem mass spectrometry. The analgesic activity was determined by tail immersion method, analgesy meter, hot plate, and acetic acid-induced writhing test. Anti-inflammatory activity was evaluated by carrageenan-induced paw inflammation in mice.Results: Anthocyanin-producing callus cultures were established in MS medium fortified with various combinations of phytohormones and sucrose. Optimal callus formation in O. aspera was initiated on cultures containing 0.5 mg/L of 2, 4-D, and 0.5 mg/L 6-benzylaminopurine (BA). In O. reticulata callus was initiated in the presence of 1.2 mg/L BA and 1.4 mg/L naphthalene acetic acid. The same hormonal combination on extended treatments turned the white friable callus into red compact callus. Anthocyanins obtained from Osbeckia species were purified and fractionated containing malvidin-3-diglucoside, delphinidin, cyanidin aglycone, and peonidin. Purified anthocyanin of O. aspera at the concentrations 50, 100, 150, and 200 mg/kg after 120 min exhibited significant analgesic activity by tail immersion method, in comparison to O. reticulata. However, with hot plate method, anthocyanin of O. reticulata produced a significant analgesic activity even at lower doses (50 and 100 mg/kg) after 120 min. However, in writhing test, theepurified anthocyanin of O. aspera significantly stopped the number of writhes at a dose of 200 mg/kg and also by the anthocyanin of O. reticulata. In the evaluation of anti-inflammatory effect using plethysmometer, anthocyanin at doses of 100,150 and 200 mg/kg started producing anti-inflammatory effect after 30 min, which lasted until 120 min.Conclusion: It is concluded from the present study that the purified anthocyanin of Osbeckia possesses potent analgesic and anti-inflammatory activities.

Indian Medicine

Pain is likely the most common symptomatic complaint in medicine; an understanding of its mechanism is critical to interpret it. Nociception refers to the detection of noxious stimuli by nociceptors, followed by transduction and transmission of the sensory nervous information from the periphery to the brain. Plants have played a unique holistic role for the provision of food, drugs, clothing, shelter, etc. Natural compounds have been extensively explored for new drug discoveries. Indeed, plants have been used as medicines for more than 5000 years, as a source of antibiotics, antineoplastic, analgesics, cardioprotective, among others. About 70–90% of the population in developing countries continue to use ancient medicines based on plant extracts. Sida cordata popularly known as “bala” is regarded as a valuable drug in the Ayurvedic System of Indian Medicine. In order to validate the ethnomedical claim of Sida cordata as pain reliever, a study was conducted to evaluate the analgesic activity of ethanolic extract of Sida cordata whole plant in laboratory animals. For centrally mediated analgesic activity, eddy’s hot plate method was employed and Pentazocine was uses as reference control. For peripherally mediated analgesic activity, acetic acid induced writhing model was employed and Dicofenac was used as reference control. Sida cordata ethanolic extract was administered orally at the doses of 100 and 200 mg/kg. In eddy’s hot plate method, both the doses of Sida cordata significantly increased the reaction time compare to vehicle control. In acetic acid induced writhing test, both the doses of Sida cordata significantly reduced the number of writhing compare to vehicle control. In both the models, the effect produced by Sida cordata was comparable to that of respective reference control. The results obtained suggest that the ethanolic extract of Sida cordata has showed marked analgesic activity in experimental animal models and this strappingly supports the ethnopharmacological applications of the plant for the target activity.

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.

Various parts of the plant are used for the treatment of a variety of ailments in ethno-medicine. Objective: To evaluate the anti-inflammatory and analgesic effect of the methanol leaf extract of Cussonia barteri. Material and methods: The leaves were air-dried, powdered and repeatedly extracted with methanol using a Soxhlet apparatus. The resulting methanol extract (100, 200 and 400 mg/kg) was evaluated for anti-inflammatory activity using carrageenan-induced paw oedema, xylene-induced ear oedema and formalin-induced arthritis tests. Analgesic effect was evaluated using acetic acid-induced mouse writhing, hot plate and tail flick tests. Results: All doses of the extract significantly (p<0.05) reduced carrageenan-induced paw oedema, however the 400 mg/kg dose gave a sustained effect. The extract significantly inhibited xylene induced ear oedema at all doses. There were no significant (p>0.05) reductions in paw swellings due to formalin. In the acetic acid induced writhing test, the extract significantly (p<0.05) decreased writhing at 400 mg/kg only. Reaction times were not significantly different from the control in the hot plate and tail flick tests. Conclusion: This study has shown that the methanol extract possesses acute anti-inflammatory and peripherally mediated analgesic effects.

Abstract Background The study was conducted to evaluate the analgesic, anti-inflammatory, antipyretic properties of ethanolic extract of Tacca integrifolia rhizome (EETI) in mice and cytotoxic effects in brine shrimp nauplii followed by a PASS prediction study for some isolated compounds of T. integrifolia. Additionally, this experiment included the in silico molecular docking and ADME/T property analyses of some phytochemicals. Methods Formalin- induced paw licking test and acetic acid-induced writhing test for analgesic activity, carrageenan-induced paw edema test for anti-inflammatory potential and Brewer’s yeast-induced pyrexia test for antipyretic activity were applied. Antinociceptive and antineoplastic activity for breast cancer were revealed with PASS program. Schrodinger suite 2015 was used to evaluate the binding interaction and ADME/T properties of selected phytoconstituents with estrogen receptor alpha. Results In formalin-induced paw licking test, EETI at the doses of 200 and 400 mg/kg BW showed highly significant inhibition of writhing in both neurogenic and inflammatory phases. While EETI also exhibited highly significant, compared to control, writhing inhibition for both the doses in acetic acid-induced writhing test. Moderate anti-inflammatory effect at a dose of 400 mg/kg BW was noticed in paw-edema test. It also showed 77.51% of maximum antipyretic effect which was significantly effective compared to standard drug paracetamol (150 mg/kg) in Brewer’s yeast-induced pyrexia test. The EETI showed potential cytotoxic activity with LC50 value of 114.46 μg/mL. The PASS prediction revealed the potential antinociceptive and antineoplastic activity of target compounds. The compounds betulinic acid, quercetin-3-α-arabinoside, catsanogenin were found to be effective in molecular docking study. Conclusion It is evident that the EETI possesses highly significant analgesic activity with remarkable anti-inflammatory and antipyretic activity. The phytoconstituents have potential antinociceptive and antineoplastic (breast cancer) activity. Graphical abstract

AbstractThe objective of this work was to study the analgesic and anti-inflammatory activity ofHealthy albino rats (150–200 g) and mice (25–50 g) were arranged and divided into five groups. Group 1 received distilled water and served as control, groups 2, 3, 4 were treated with TG stem extract (100, 200, 400 mg/kg) and group 5 received standard drug. For analgesic activity, the radiant heat method and writhing test were used, and for anti-inflammatory activity, the paw oedema model and granuloma pouch method were used. Statistical analysis was done by one-way analysis of variance followed by the t-test.In the radiant heat method, there was a dose-dependent increase in reaction time in TG stem extract (100, 200, 400 mg/kg) and standard drug (buprenorphine). In the writhing test, TG stem extract (200, 400 mg/kg) and aspirin decreased the number of writhes which was significant (p<0.01, p<0.001) as compared to controls. The percentage protection was 8.88%, 15.55%, 22.22% and 35.55% in groups 2, 3, 4 and 5, respectively. In the rat paw oedema test, TG stem extract (200, 400 mg/kg) and aspirin showed 20%, 40% and 54% inhibition of oedema which was statistically significant (p<0.05, p<0.01, p<0.001), respectively, as compared to control at the end of 4 h. In the granuloma pouch method, TG stem extract (100, 200, 400 mg/kg) and aspirin showed 13.33%, 22.22%, 33.33% and 66.66% inhibition of granuloma, respectively, which was significant (p<0.05, p<0.01, p<0.001).TG stem extract possesses significant anti-inflammatory and analgesic activity.
