PHYTOCHEMICAL ANALYSIS AND THE ANTIINFLAMMATORY ACTIVITIES OF DICHLOROMETHANE FRACTION OF METHHANOL EXTRACT OF CRATEVA ADANSONII

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.
