Pharmacological Potential of Anti-Inflammatory and Anti Nociceptive Activity of Bioactive Fractions from Leaves of Maytenus emarginata

The antinociceptive & anti-inflammatory activities of extract were compared to dose of Phenylbutazone. The phytochemical secondary metabolites tested for include alkaloids, cardiac glycosides, flavonoids, phenols, saponins, steroids and terpenoids. Maytenus emarginata leaves extract demonstrated significant antinociceptive and anti- inflammatory effects in a dose-dependent manner. The extract dose at 200mg/kg bw exhibited the highest antinociceptive and anti-inflammatory activities & its activities were comparable to those of the respective reference drugs. BFLME (suspended in 1% carboxy methyl cellulose) in doses of 50, 100 and 200 mg/kg caused a dose-dependent inhibition of swelling caused by carrageenin equivalent to 30.2–63.2% protection (P<0.05– P<0.001) and in cotton pellet granuloma, 47.2–45.4% protection (P<0.01-P<0.001) was observed from inflammation. There was a significant increase in analgesiometer force induced pain in rat equivalent to 98.1–146.5% protection (P<0.01-P<0.001) and 7.19–37.8 % (P<0.05–P<0.001) protection against Acetic acid induced writhing. Phytochemical screening of the extract indicated the presence of alkaloids, cardiac glycosides, flavonoids, phenols, saponins, steroids and terpenoids. The present study therefore demonstrated the antinociceptive and anti-inflammatory properties of bioactive fraction of ethyl acetate extract from leaves of M. emarginata (BFLME), hence providing a basis for further research that may result in pure compounds that can be advanced into drug discovery.

Phytochemical and pharmacological investigations of Pseudarthria viscida (L.) Wight & Arnott

Pseudarthria viscida L. Wight & Arnott belongs to family Leguminosae commonly called as Salaparni is an essential component of potent Ayurvedic formulations. It has been screened for antioxidant, cytotoxic, antidiabetic & anti-diarrhoeal activity. Currently, there is no enough scientific evidence or literary resources on the anti-inflammatory & antipyretic activity of this plant. Therefore, this study was aimed at exploring P.viscida for its therapeutic potentials as anti-inflammatory & antipyretic agent. A research was conducted to evaluate the anti-inflammatory property ( inflammation-induced to rat paw oedema by carrageenan & cotton pellet granuloma) & antipyretic (Pyrexia induced by brewer’s yeast) activities of petroleum ether extract of Pseudarthria viscida (PEPV) stems & roots in albino rats. Pre-treatment of the animals with the plant extract (100 & 200 mg/kg, p.o.) has prevented the inflammation produced evident by the change in volume of paw oedema which is proportional to the dose. A maximum effect was seen at 200 mg/kg, which was competent to Indomethacin (10 mg/kg, i.p). The antipyretic effect of PEPV (100 & 200 mg/kg, p.o.), measured as percentage lowering in body heat was compared with st&ard, Paracetamol (150 mg/kg, p.o.). The anti-inflammatory & antipyretic activities showed dose-related response at 100 mg/kg & 200 mg/kg, when compared to the st&ard. This current research investigated & advocates the anti pyretic property & anti-inflammatory potency of Pseudarthria viscida, and it supports the application of the plant in medicine as per ethnopharmacology.

Inflammation lowering property of pistacia atlantica in cotton pellet granuloma

There are few defence mechanisms by which the body identifies and recovers from any physical injuries or external damage-causing stress and stimuli. This is through inflammation wherein the pain and the healing enzymes release into the bloodstream and cause pain and swelling that causes protection from those damages. The most important of the causative factors of the inflammation is the oxidative damage and the physiological stress. There were investigations on the herbs that were used in the treatment of diseases and were claimed to contain very limited or without side effects. Thus, they gained importance these days and were used in the treatment of major diseases like cancer and heart problems. Even though their use was extended from the traditional forms to advanced medicine, their scientific establishment of the proof and validate them for their activities is utmost important. Thus there were gaining interest in the medical and research field to perform the researches on the herbs and medicinal plants to prove their activity. The plant leaves of Pistacia atlantica were extracted with ethanol and water mixture using an ultrasonication. It was tested for the anti-inflammatory potential in various doses like 100, 200, 400 and 600 mg.kg body weight in the swiss albino rats in the cotton pellet induced granuloma method and the extracts showed significant dose-dependent activity compared with the standard indomethacin drug.

Effects of the Ethanolic Extract of Bulbostylis coleotricha (Hochst.Exa. Rich.) on Inflammation in Adult Wistar Rats

Bulbostylis coleotricha (family Cyperaceae) is a stem-tufted plant found in tropical region of Africa. It is locally used in treating various ailments among the African folks. Despite the high esteem this plant is held in Africa, there is dearth of scientific studies on B. coleotricha. This, in addition to the alarming increase in inflammatory diseases around the world, makes the present study to focus on the effect of the B. coleotricha extract on laboratory induced inflammation. Twenty-five adult Wistar rats, weighing between 225-287g were used for this experiment, and were randomly divided into five groups of five rats per group. The groups were labelled and treated as follow: Group 1, the negative control group, was treated with 10 ml/kg body weight (b. w.) of distilled water. Groups 2, 3 and 4, the treated groups, were treated with 25 mg, 50 mg and 100 mg/kg b. w. of ethanolic extract of B. coleotricha respectively. Doses were based on the local information on B. coleotricha usages. Group 5, the positive control group, was treated with 5mg/kg b. w. of indomethacin. In all the groups, the effects of all treatments were checked on induced inflammation using cotton pellet granuloma and carrageenan induced paw oedema model. The results in the two models used showed that ethanolic extract of B. coleotricha significantly inhibited inflammation in the treated groups. In the cotton pellet granuloma test the extract at the dose of 100 mg reduced granuloma formation from 30.2 ± 2.4 mg to 11.2 ± 2.6 mg reduced paw oedema from 7.0 ± 1.7 mm to 2.4 ± 0.8 mm (control is 100 mg/kg). In conclusion, this study established that Bulbostylis coleotricha plant is effective in the treatment of inflammation and can be explored in the treatment of various diseases with underlying inflammation.Keywords: Bulbostylis coleotricha, Inflammation, Cotton Pellet Granuloma, Carrageenan-induced Paw Oedema
