Introduction: Ferulago angulata from the Apiaceae family, has high flavonoid content and is detected to have anti-nociceptive and anti-inflammatory effects. Objectives: In this study, we sought to determine the components of essential oil and to estimate total phenol and flavonoid contents of its various extracts. We also aimed to find out the anti-nociceptive and anti-inflammatory effects of essential oil, hydro-alcoholic and phenolic extracts of F. angulata aerial parts. Materials and Methods: The plant’s essential oil and extracts were prepared according to standard methods. Acetic acid, hot plate and formalin tests were used to investigate anti-nociceptive effects. Additionally, carrageenan and croton oil tests were used to evaluate anti-inflammatory effects. Results: Ferulago angulata aerial parts yielded 0.2% (v/w) yellowish essential oil. The gas chromatography/ mass spectrometry (GC-MS) of essential oil identified 82 compounds, which represented 98.9% of the essential oil. Thymol (7.9%), spathulenol (6.5%), trans-anethol (6.4%), myristicin (5.1%) and alpha-pinene (4.5%) were the main components. In acetic acid and formalin tests, the essential oil, hydro-alcoholic and phenolic extracts showed significant anti-nociceptive effects (P<0.001). In hot plate test, morphine which was used as standard drug, revealed significant anti-nociceptive effect while the plant extracts and essential oil were ineffective. High dose of the extracts and essential oil in croton oil test (P<0.001) and high dose of hydro-alcoholic and phenolic extracts in carrageenan test (P<0.05) reduced the inflammation. Conclusion: Ferulago angulata extracts and essential oil have anti-nociceptive and anti-inflammatory effects. However, further studies are needed to clarify their mechanism of actions.

The analgesic and anti-inflammatory properties of Zhumeria majdae essential oil were investigated in mice and rats. The analgesic activity of the oil was assessed by acetic acid-induced writhing and Eddy's hot plate methods while the acute anti-inflammatory effect was investigated by inflammatory paw edema in rat. Z. majdae oil significantly decreased the number of acetic acid-induced writhes in mice compared with animals that received vehicle only. Also it exhibited a central analgesic effect as evidenced by a significant increase in reaction time in the hot plate method. The oil also significantly reduced carrageenan induced paw edema in rats. The inhibitory activity of Z. majdae essential oil was found to be very close to that of the standard drug, diclofenac sodium (50 mg/kg). The studied oil was analyzed by GC and GC–MS and seventeen constituents were identified, representing 99.2% of the oil. The major components of the oil were characterized as linalool (63.4%) and camphor (27.5%), which might be responsible for these observed activities. The results suggest that Z. majdae essential oil possesses biologically active constituent(s) that have significant activity against acute inflammation and have central and peripheral antinociceptive effects which support the ethnomedicinal claims of the plant application in the management of pain and inflammation.

Warionia saharae Benth & Coss (W.s) (Asteraceae) is a monospecific genus endemic to Algeria and Morocco. Its leaves are used in their traditional medicine, such as gastrointestinal and inflammatory diseases; for instance, rheumatoid arthritis treatment. In this work, our team investigated the anti-inflammatory and analgesic effects of essential oil extracted from the dried upper parts of Warionia saharae based on different standard experimental test models. The analgesic activity was assessed by central and peripheral models, such as “hot plate” and “writhing” tests on Swiss albino mice. The hot plate test used latency measurements to assess acute cutaneous pain sensitivity, as a result; the latency of the hind-paw pain response was by licking and either shaking or jumping, those occurrences were recorded. Writhing test as a chemical method used to induce pain of peripheral origin in mice by injecting acetic acid intraperitoneally (IP). This results in characteristic stretching behavior of the animals (cramps and contortions). The evaluation of the analgesic activity, shows that the essential oil of this plant induces a decrease in the number of abdominal cramps in the contortion test and a maximum inhibition of pain. As for the anti-inflammatory effect, it was studied by the “paw edema” test, a phlogogenic agent (formaldehyde) was used to stimulate inflammation in the paws of mice. Anti-inflammatory properties can be observed by inhibiting this edema compared to the standard drug Diclofenac. In conclusion, Warionia saharae essential oil (75 mg/kg) showed a strong anti-inflammatory and analgesic activities which supports the conventional use of this plant in traditional medicine.

Background: A major goal of pain management is to provide pain relief that is clinically meaningful, sustained, and associated with minimum and reversible adverse effects. Since single analgesic drug is not effective in all patients, there is a need either to develop new and more effective drugs or to identify favourable combinations of drugs that are already available. The aim of the present was to evaluate the analgesic and anti-inflammatory activity of tramadol and pregabalin when used alone or in combination in animal models of pain and inflammation.Methods: The animals (rats and mice) were divided into eight groups with six animals in each group. Analgesia was assessed by acetic acid induced writhing and tail flick methods in mice and hot plate method in rats. Paw oedema model in rats after induction with 0.1 ml of 1% carrageenan was used to assess the anti‑inflammatory activity. The percentage inhibition of writhes and prolongation of reaction time were used for assessing analgesic activity and reduction in paw volume was used for assessing anti-inflammatory activity. The results obtained were analysed by ANOVA and Tukey HSD Post-hoc Test.Results: Treatment with tramadol pregabalin alone or in combination reduced writhing episodes significantly in acetic acid induced writhing in mice as compared to control indicating its analgesic effect and the highest percentage inhibition of pain was seen with high dose tramadol plus pregabalin. Treatment in Hot plate and Tail flick methods significantly prolonged the reaction time at all time points.Conclusions: Tramadol when combined with pregabalin may enhance its anti-nociceptive effects. If confirmed in additional models of acute and/or chronic pain this combination might be useful in the clinical management of pain not associated with inflammation.

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.

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.

Ferula stenocarpa is an aromatic herb whose fruits are widely used in Persian traditional medicine as a painkiller and to relive inflammation-based disorders. Considering the higher content of essential oil in the fruits, the oil’s anti-inflammatory and analgesic activities were investigated in an animal model in vivo. The analgesic effect of Ferula stenocarpa fruits essential oil was evaluated via testing the writhing triggered by acetic acid examination and hot plate technique. Moreover, the acute anti-inflammatory effects were studied through the paw edema triggered in mice. Using 20 and 40 mg/kg of the oil revealed an analgesic impact considering the increment in the reaction time needed for the hot plate approach. Furthermore, all examined doses of the oil caused a reduction in the frequency of writhes in the mice. It was observed that the oil (40 mg/kg) followed by 10 and 20 mg/kg caused inflammatory reduction. The findings indicated that the oil may possess significant activities against acute inflammation. It had both peripheral and central pain-killing impacts. α-Pinene (43.1%) and β-pinene (22.9%) as the main constituents of the oil, can be considered as the responsible compounds to manage inflammation and pain.

The qualitative and quantitative composition of EOZ were determined with gas chromatography/Mass spectrometer. The interaction between EOZ and Ver in antinociceptive activity was evaluated by using acetic acid-induced writhing, hot plate, and tail flick tests in mice and in isolated toad sciatic nerve test.Results. Linalool, limonene, and sabinene are the major components of EOZ. EOZ (middle-dose: 40 mg·kg−1, high-dose: 80 mg·kg−1) and EOZ + Ver (Each dose group) have remarkable analgesic effects on pain in mice induced by acetic acid-induced writhing, hot plate, and tail flick tests. Low-dose EOZ (20 mg·kg−1) had no analgesic action, but when it is combined with Ver it has shown significant antinociception. Verapamil has a faint analgesic effect but was not able to inhibit action potential transmission in toad sciatic nerve. EOZ (0.2%) and EOZ + Ver (0.2% + 0.05%) also inhibited action potential transmission in toad sciatic nerve. Combination of EOZ with Ver had a greater analgesic effect and inhibition of nerve action potential transmission compared to its components EOZ and Ver.Conclusion. The combination of EOZ with Ver produces a synergistic analgesic effect.

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.

The integration of green natural chemical resources in agricultural, industrial, and pharmaceutical applications allures researchers and scientistic worldwide. Cleome amblyocarpa has been reported as an important medicinal plant. However, its essential oil (EO) has not been well studied; therefore, the present study aimed to characterize the chemical composition of the C. amblyocarpa, collected from Egypt, and assess the allelopathic, antioxidant, and anti-inflammatory activities of its EO. The EO of C. amblyocarpa was extracted by hydrodistillation and characterized via gas chromatography–mass spectrometry (GC-MS). The chemometric analysis of the EO composition of the present studied ecospecies and the other reported ecospecies was studied. The allelopathic activity of the EO was evaluated against the weed Dactyloctenium aegyptium. Additionally, antioxidant and anti-inflammatory activities were determined. Forty-eight compounds, with a prespondence of sesquiterpenes, were recorded. The major compounds were caryophyllene oxide (36.01%), hexahydrofarnesyl acetone (7.92%), alloaromadendrene epoxide (6.17%), myrtenyl acetate (5.73%), isoshyobunone (4.52%), shyobunol (4.19%), and trans-caryophyllene (3.45%). The chemometric analysis revealed inconsistency in the EO composition among various studied ecospecies, where it could be ascribed to the environmental and climatic conditions. The EO showed substantial allelopathic inhibitory activity against the germination, seedling root, and shoot growth of D. aegyptium, with IC50 values of 54.78, 57.10, and 74.07 mg L−1. Additionally, the EO showed strong antioxidant potentiality based on the IC50 values of 4.52 mg mL−1 compared to 2.11 mg mL−1 of the ascorbic acid as standard. Moreover, this oil showed significant anti-inflammation via the suppression of lipoxygenase (LOX) and cyclooxygenases (COX1, and COX2), along with membrane stabilization. Further study is recommended for analysis of the activity of pure authentic materials of the major compounds either singularly or in combination, as well as for evaluation of their mechanism(s) and modes of action as antioxidants or allelochemicals.
