Wound healing activity of embelin isolated from the ethanol extract of leaves of Embelia ribes Burm.

Ethanol extract of the leaves of Embelia ribes Burm. (Myrsinaceae) and its isolated quinone compound embelin were screened for wound healing activity by excision, incision and dead space wound models on Swiss Albino Rats. Significant wound healing activity was observed in both ethanol crude extract (30 mg/ml) and the constituent treated groups. In embelin treated groups (4 mg/ml of 0.2% sodium alginate gel), epithelialization of the incision wound was faster with a high rate of wound contraction. The tensile strength of the incision wound was significantly increased than the ethanol extract. In dead space wound model also the weight of the granulation was increased indicating increase in collagenation. The histological examination of the granulation tissue of embelin treated group showed increased cross-linking of collagen fibers and absence of monocytes. The wound healing effect was comparatively evaluated with the standard skin ointment Framycetin.

Evaluation of acute toxicity and hepatoprotective activity of the methanolic extract of Dichrostachys cinerea (Wight and Arn.) leaves.

BACKGROUND: D. cinerea are the chief source of drug compounds that are active against various ailments such as jaundice, inflammations rheumatism, fever, asthma, body ache, chest problems, toothache, ulcers, wounds, eye diseases and have an aphrodisiac property. In present study, It was aimed to test the hepatoprotective activity of the plant. MATERIAL AND METHODS: The methanolic extract of Dichrostachys cinerea (Mimoseae) leaves was subjected to evaluation of acute toxicity and hepatoprotective property, using albino mice and rats. The parameters for estimation of liver function, based on serum markers such as total bilirubin, total protein, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase with histopathological profile of the liver tissue, were studied consequently. RESULTS: The methanolic extract did not show any mortality up to a dose of 3500 mg/kg body weight. The methanolic extract showed significant hepatoprotectivity. The histopathological profile of the drug-treated liver tissue demonstrated similar morphology as that of controls. CONCLUSIONS: Methanolic extract of Dichrostachys cinerea was found to have significant hepatoprotective activity.
