Anti-inflammatory and analgesic activities of ethanolic extract and two limonoids from Melia toosendan fruit

AIM OF STUDY: The fruit of Melia toosendan Sieb. et Zucc. (MTF) is a traditional Chinese herbal medicine in the treatment of stomachache and many acute or chronic inflammations, as well as ascariasis. This paper aimed to investigate the anti-inflammatory and analgesic activities of the MTF extract and two main limonoid-type triterpenoids isolated from MTF. MATERIALS AND METHODS: The ethanolic extract of MTF and two limonoids, isotoosendanin (1) and 1-O-tigloyl-1-O-debenzoylohchinal (2) were evaluated for their anti-inflammatory and analgesic activities. Acetic acid-induced vascular permeability and lambda-carrageenan-induced hind paw edema tests in mice were used to investigate anti-inflammatory activity; and acetic acid-induced writhing and hot-plate tests in mice were used to determine analgesic effect. RESULTS: Both the ethanolic extract and two limonoids displayed significant anti-inflammatory effects. Although the ethanolic extract showed remarkable analgesic effects in both writhing and hot-plate tests, the two limonoids had analgesic effects just in writhing test. CONCLUSION: The results suggested that the ethanolic extract of MTF had obvious anti-inflammatory and analgesic activities, and the two limonoids were the active constituents contributing to the anti-inflammatory and analgesic effects of MTF.     

Analgesic and antiinflammatory activities of taxoids from Taxus wallichiana Zucc

A study was conducted to identify constituents that might be responsible for analgesic and antiinflammatory conditions. Tasumatrol B, 1,13-diacetyl-10-deacetylbaccatin III (10-DAD) and 4-deacetylbaccatin III (4-DAB) were isolated from the bark extract of Taxus wallichiana Zucc. All the compounds were assessed for analgesic and antiinflammatory activities using an acetic acid-induced writhing model, a hot-plate test, a carrageenan-induced paw oedema model, a cotton-pellet oedema model and in vitro lipoxygenase inhibitory assay. All the compounds, especially tasumatrol B, revealed significant analgesic activity in comparison to a saline group based on an acetic acid-induced model. Similarly all of the test compounds, particularly tasumatrol B, showed significant antiinflammatory activity. However, all the compounds failed to exhibit any considerable activity in of the hot-plate test and the in vitro lipoxygenase inhibitory assay. This study has highlighted the potential of tasumatrol B to be further explored as a new lead compound for the management of pain and inflammation, one that has been discovered by scientific validation of the traditional medicinal use of T. wallichiana Zucc.

Anti-inflammatory and analgesic effects of ethanol and aqueous extracts of Pterocephalus hookeri (C.B. Clarke) Höeck

Aim of the study

This study evaluates the anti-inflammatory and analgesic activities of the ethanol and aqueous extracts of a Tibetan herb Pterocephalus hookeri (C.B. Clarke) Höeck to provide experimental evidence for its traditional use such as cold, flu and rheumatoid arthritis.

Materials and methods

Investigations on the analgesic effects of P. hookeri (C.B. Clarke) Höeck were carried out, including hot-plate test and acetic acid-induced writhing. The anti-inflammatory activities were observed by utilizing the following models: carrageenin-induced edema of the hind paw of rats, cotton pellet-induced granuloma formation in rats, acetic acid-induced permeability, and xylene-induced ear edema in mice. The effects of the administration of indomethacin were also studied.

Results

It has been shown that the ethanol and aqueous extracts significantly increased the hot-plate pain threshold and reduced acetic acid-induced writhing response in mice. The ethanol and aqueous extracts remarkably inhibited the increase in vascular permeability induced by acetic acid and ear edema induced by xylene. The ethanol extract also significantly decreased the carrageenin-induced rat paw edema perimeter and inhibited the increase of granuloma weight.

Conclusion

The results show that the ethanol and aqueous extracts have both central and peripheral analgesic activities and as anti-inflammatory effects, supporting the traditional application of this herb in treating various diseases associated with inflammation and pain.     

Anti-inflammatory and analgesic properties of Drynaria quercifolia (L.) J. Smith

Ethnopharmacological relevance

Drynaria quercifolia (L.) J. Smith (Polypodiaceae), has been widely used by ethnic groups of India to treat inflammation, rheumatism, headache, bone fracture, jaundice, etc.

Aim of the study

To evaluate the anti-inflammatory and analgesic properties of the ethanolic extract of rhizome of Drynaria quercifolia (DQ) and its phytochemical profile.

Materials and methods

DQ was used to evaluate the anti-inflammatory and analgesic effects using carrageenan-induced paw oedema/cotton pellet-induced granuloma in Wistar rats and acetic acid-induced writhing/formalin-induced paw licking test in Swiss albino mice respectively.

Results

Oral administration of DQ produced significant inhibition of carrageenan-induced paw oedema and granuloma formation in rats, almost comparable to that caused by indomethacin. DQ significantly attenuated acute and delayed phases of formalin-induced pain and acetic acid-induced writhing episodes in mice. The analgesia was comparable to that produced by sodium salicylate and aspirin respectively. Phytochemical analysis gave positive tests for catechin, coumarins, flavonoids, phenolics, saponin, steroids, tannins, and triterpenes. The total phenolics in DQ was 244 mg/g and naringin content was 0.048%.

Conclusion

The results suggest the presence of potent anti-inflammatory and analgesic principles in DQ that justifies its use for alleviating painful inflammatory conditions.     

Analgesic and anti-inflammatory activities of aqueous extract from Glycine tomentella root in mice

In the present study, we have investigated the analgesic effect of the aqueous extract of the root of Glycine tomentella (AGT) using models of acetic acid-induced writhing response and formalin test, the anti-inflammatory effect of AGT using model of lambda-carrageenan-induced paw edema. In order to investigate the anti-inflammatory mechanism of AGT, we have detected the activities of glutathione peroxidase (GPx) and glutathione reductase (GRx) in the liver and the levels of malondialdehyde (MDA) and NO in the edema paw. In the analgesic test, AGT (0.5 and 1.0 g/kg) decreased the acetic acid-induced writhing response and the licking time on the late phase in the formalin test. In the anti-inflammatory test, AGT (0.5 and 1.0 g/kg) decreased the paw edema at the third, fourth, fifth and sixth hour after lambda-carrageenan administration, and increased the activities of SOD, GPx and GRx in the liver tissue and decreased the MDA level in the edema paw at the third hour after lambda-carrageenan injection. However, AGT could not affect the NO level which induced by lambda-carrageenan. These results suggested that AGT possessed analgesic and anti-inflammatory effects. The anti-inflammatory mechanism of AGT might be related to the decrease in the level of MDA in the edema paw via increasing the activities of SOD, GPx and GRx in the liver.
