The ethanol crude extract of stem bark of Holoptelea integrifolia Planch. traditionally used in Indian system of medicine was screened for its antioxidant activity using α-tocopherol as standard antioxidant. The free radical scavenging potential of the extract was evaluated by two different antioxidant methods; ferric thiocyanate and thiobarbituric acid method. The ethanol extract was found to ...

Structures of condensed tannins from the stem bark and fine root of Casuarina equisetifolia were identified using MALDI-TOF MS and HPLC analyses. The condensed tannins from stem bark and fine root consist predominantly of procyanidin combined with prodelphinidin and propelargonidin, and epicatechin is the main extension unit. The condensed tannins had different polymer chain lengths, varying fr...

Poverty, drug resistance and other factors including increasing difficulty in the control of mosquitoes (the vector of the causative organism of malaria), have led to a growing interest in phytochemical research. The antioxidant activity of Newbouldia laevis stem bark was investigated. Air dried stem bark of N. laevis was powdered and extracted with 95 % v/v methanol by maceration, and the extr...

This study examined the antinociceptive and antiinflammatory activities of the stem bark of the traditional medicinal plant, Hildegardia poulifolia (Sterculiaceae), an endangered species. Methanolic bark extract of this species was investigated for the antinociceptive effect by using acetic acid-induced writhing and hot plate methods in albino mice and antiinflammatory activity by carrageenan, ...

Stem bark of Acacia nilotica, Delbergia sissoo, Delonix regia, Polyalthia longifolia, Prosopis cineraria, and Zyziphus mauritiana, and leaves of Catharanthus roseus, Mentha arvensis, Murraya koinigii, Ocimum basilicum, Tabernaemontana divaricata, Tinospora cordifolia and Tribulus terrestris were analyzed for their total phenolic and flavonois content as well as antioxidant activity. Stem bark o...

BACKGROUND This study aims to understand how the stem bark of Stryphnodendron rotundifolium Mart. is used by a rural community in the savanna of Northeastern Brazil, associated with a preliminary assessment involving plant population structure and extractivism in the main sites of collection. METHODS A population structure study and analysis of bark extractivism was conducted in two sites: on...

The present work has been under taken to study the antibacterial activity of stem bark extracts of O. indicum against disease causing gram negative and gram positive bacteria. Antimicrobial activity of solvent extracts of stem bark of Oroxylum indicum has been studied to find out its activity against four important bacterial strains Bacillus subtilis, B. cereus, Staphylococcus albus and S. aure...

Ochrosia oppositifolia can be found along the coastline and is locally known as ‘Mempelam pasih’ or ‘Mangga laut’. In this study, the alkaloids from the leaves, stem-bark and roots were extracted and tested for their antibacterial activity. So far, no previous studies have been carried out to determine the antibacterial potential of the extracts. Each extract was tested using disc-diffusion and...

OBJECTIVE To evaluate the antitumor activity of Manilkara zapota (M. zapota) L. stem bark against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. METHODS The in vivo antitumour activity of the ethyl acetate extract of stem bark of M. zapota L. (EASM) was evaluated at 50, 100 and 200 mg/kg bw against EAC using mean survival time. After administration of the extract of M. zapota, viable E...
