In the present study the anti-inflammatory, analgesic activity and mechanistic pathway of Centratherum anthelminticum (Willd.) Kuntze (CA), Cissus quadrangularis Linn. (CQ) and Kigelia pinnata DC (KP) was tested in rats using carrageenan induced paw edema method. The central analgesic activity was assessed by radiant heat method, hot plate method, and tail immersion method. The peripheral analgesic action was estimated using acetic acid induced writhing test. To establish the mechanism of action of the hydroalcoholic extract, membrane stabilization, antioxidant, antihistaminic, muscle strength, and coordination activity were performed. In anti-inflammatory activity; CA, CQ, and KP showed maximum inhibition of 77%, 70% and 50% respectively. In analgesic activity, CA and CQ treated animals responded propitiously to both central and peripheral analgesia, but KP treated animals demonstrated significant activity only for peripheral analgesia. This can be attributed to membrane stabilization, anti-oxidant, and antihistaminic potential. All the three test drugs have shown both anti-inflammatory activity and analgesic activity with varying potency and mechanisms of...

An ethnomedicinal survey was carried out during August 2008 to October 2008 among tribal medicinal practitioners of the Murong tribes. Various Murong tribal practitioners practiced in their localities for treating different kinds of disease of Ramgarh Upazila, Khagrachari districts of Chittagong Hill Tracts Region in Bangladesh. We observed to use 40 plants species belonging to 29 families in the various treatment of disease. This diversity only adds to the uniqueness of the traditional medicinal practices and opens up scientific possibilities of discovering different drugs from different medicinal plants to treat any given ailment. These tribal medicinal plants were mostly used for the treatment of constipation, cough, fever, diarrhoea, dysentery, diuretic, diabetes, eczema, itches, jaundice, skin disease, vomiting, wound, joint pain and worm. The plants were collected and identified botanically along with their scientific name, local name, family name, habit, parts used and medicinal uses. This detailed information will be helpful for the pharmacognosist, botanist and pharmacologist for the collection and identification of the plant for their research...

Thevetia peruviana is found distributed throughout tropical parts of India. Their leaves are used as cardiotonic and diuretic. Flowers of plant Thevetia peruviana were reported to possess good medicinal value in the traditional system of medicine; the present investigation deals with macroscopic, microscopic and preliminary phytochemical investigation of flowers of Thevetia peruviana which includes pharmacognostical parameters, physiochemical parameters like ash values, extractive values, and moisture content. The main aim of the present investigation is to study the macro, microscopic and some other pharmacognostic characters and physicochemical standards of flowers of Thevetia peruviana Pers. which could be used to prepare a monograph for the proper identification of the plants....

Oxidative stress has been implicated in various pathological diseases like neurodegenerative disorders, stroke, cancer, inflammation, atherosclerosis, etc., which upshots when the production of reactive oxygen species overwhelms the antioxidant defense mechanism. Nowadays, development of drugs with antioxidant potential gained utmost importance therapeutically to treat many pathological diseases. Plant-derived anti-oxidants were proven to be more effective than synthetic antioxidants. With this as focus, the present study investigated the antioxidant potential of punicalagin (PG) in an in-vitro system of goat liver slices imperiled to oxidative stress. Precision cut goat liver slices are used as an in-vitro model for the evaluation of anti-oxidant activity because it crafts in-vivo tissue environment and helps in curtailing the use of intact animals. In our study, hydrogen peroxide is used as an oxidant to create oxidative stress to the liver slices. Hydrogen peroxide treated liver slices showed a significant decrease in both enzymatic and non-enzymatic antioxidant levels as compared with normal liver slices. PG treated liver slices showed significant improvement in both enzymatic and non-enzymatic antioxidant...

The present study was conducted to explore the antioxidant and radical scavenging activities of essential oil extracted from the leaves of plants of family Lamiaceae from Morni hills in the north-eastern part of the state of Haryana, India. Ten plants- Hyptis suaveolens, Mentha longifolia, M. pulegium, Ocimum basilicum, Plectranthus incanus, P. striatus, Pogostemon benghalensis, Rabdosia rugosa, Salvia plebeia and Scutellaria angulosa of the family Lamiaceae were explored from the area and the essential oil from their leaves was extracted. The maximum oil yield was found in leaves of O. basilicum, while the oil yield was the minimum in leaves of P. incanus. The density of oil was found to be the maximum in H. suaveolens, while it was the minimum in P. incanus and S. angulosa. The essential oils of all the plants exhibited DPPH radical scavenging activity; however, it was best exhibited by S. angulosa (with least IC50 value) in comparison to standard butylated hydroxytoluene (BHT). Further, the oil also exhibited total antioxidant activity, which was found to...
