ABSTRACT Inflammation is a complex biological response of vascular tissue to harmful stimuli such as pathogen, damage cells or irritants (Ryan & Majno, 1983). The urgency generated by increased rate of stroke, atherosclerosis attribute due to prolonged use of cyclooxygenase-1 and Cyclooxygenase- 2 inhibitors have accelerated anti-inflammatory drug research over the last decade while synthetic pharmaceutical agents continued to dominate research (Ryan & Majno, 1983). Attention increasingly has been directed to natural products. These are often more affordable and available and sometimes are perceived as more effective than conventional anti- inflammatory drugs. Anti-inflammation was carried out using 12 rats which was divided into three groups of 4 rats each. Group 1 and 2 served as the negative and positive control respectively. Group 3 received 25mg/kg b.w. of the dichloromethane fraction of methanol extract of Crateva adansonii showed significance anti-inflammatory activity when compared with the standard difference used.

ABSTRACT This research investigated the phytochemical and anti-inflammatory properties of methanol extract of Crateva adansonii stem bark. Although several edible and non-edible plants parts are used in inflammatory treatment, many record has been found of the use of Crateva adansonii stem bark. For this research, fresh stem bark of Crateva... Continue Reading
