The analgesic properties of dried leaves of Capraria biflora were investigated. The aqueous extract (50-200 mg kg(-1)) produced moderate inhibition of acetic acid-induced writhing in mice. At the same doses, a better analgesic effect was observed on the hot plate test.
The ethanol and water extracts of Capparis zeylanica leaves showed dose-dependent and significant (P<0.05) increases in pain threshold in tail-immersion test. Moreover, both the extracts (100-200 mg/kg) exhibited a dose-dependent inhibition of writhing and also showed a significant (P<0.001)
The ethanol and water extracts of Sansevieria trifasciata leaves showed dose-dependent and significant (P < 0.05) increase in pain threshold in tail-immersion test. Moreover, both the extracts (100 - 200 mg/kg) exhibited a dose-dependent inhibition of writhing and also showed a significant (P <
The methanol extract of leaves of Aegle marmelos at a dose level of 200 and 300 mg/kg showed significant analgesic activity on acetic acid-induced writhing and tail flick test in mice.
This paper describes a phytochemical and pharmacological study with Calophyllum brasiliense leaves, a medicinal plant employed in folk medicine for the treatment of several ailments. Based on spectroscopic evidence, five phenolic compounds were identified as hyperin (hyperoside), amentoflavone,
* Author for correspondence and reprint requests Z. Naturforsch. 64c, 809-812 (2009); received May 7/July 23, 2009 Menthalactone, a new long-chain alkene with a bicyclic lactone moiety, was isolated as an analgesic constituent from the leaves of Mentha cordifolia Opiz. At a dosage of 100 mg/ kg
An alcoholic extract of Sterculia foetida L. leaves was subjected to pharmacological screening using various animal models. The extract caused reduced exploratory activity in mice. Further it potentiated pentobarbitone sleeping time in normal and chronic pentobarbitone-treated mice. It also
The methanol extract of the leaves of E. adenophorum (100, 200 and 300 mg/kg, po) showed significant analgesic activity, as compared to standard drugs diclofenac sodium and pentazocine, employing acetic acid-induced writhing test, tail immersion test and tail flick test models.
Some phytoconstituents present in the R. Gardneriana Pl. Tr. leaves, a Brazilian medicinal plant, were isolated by column chromatography. Their preliminary analgesic effects were evaluated against formalin-induced pain in mice. The results demonstrated that four biflavonoids, identified as
The aqueous extracts of Datura fastuosa leaves and seeds were evaluated for the analgesic effect on acetic acid-induced writhing and hot plate reaction in mice. According to the results, D. fastuosa leaves and seeds extracts at oral doses of 400 and 800 mg/kg are effective as analgesic. The
The various extracts of leaves Holoptelea integrifolia (Ulmaceae) were investigated for analgesic activity in mice by tail flick method. The fresh plant leaves of H. integrifolia were collected, dried, cleaned, weighed and chopped into small pieces and percolated in ethanol. The fractionation of
BACKGROUND
Our present study was carried out to explore the potential role of the methanol extract from the leavesof Phlogocanthus thyrsiflorus (PT) Nees. in central and peripheral analgesic activities using hot plate and acetic acid-induced writhing methods. We also tested the antiinflammatory
The analgesic activity of the methanolic extracts of the roots and leaves of Calliandra portoricensis was investigated in mice and rats using acetic acid-induced writhing and formalin tests. The extracts given orally at the doses of 200, 400, 600 mg/kg showed a dose-dependent activity in the tests
The ethanolic extract of the leaves of Tamarindus indicus was investigated for its anti inflammatory and analgesic actions. The anti inflammatory activity was studied using carrageenin induced hind paw edema in rats and analgesic activity using chemical writhing test and tail clip method in mice and
