Phytochemical And Anti-Inflammatory Properties Of Methanol Extract Of Crateva Adansoni Stem Bark
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 adansonii were
collected from Asata village in Enugu State. The cuttings were authenticated
at the Bioresource development centre. They were then dried at room
temperature for one month in an open lab space, grounded into powder and
weighed on a beam balance as 460.6g. The powder was soaked for twenty-
four to fourty-eight hours in methanol to get a methanol extract and then
concentrated into paste at a set temperature range of 30-550C in a water
bath. A population of twenty adult wistar Albino rats was used for anti-
inflammatory test. The rats were divided into five (5) groups of four (4)
albino rats each. They were administered 3% tween-80 mixed with
dichloromethane extract of Crateva adansonii and the control was
administered with 0.5ml of 3% tween-80. Acute inflammation was induced
an hour after test substances were administered by injecting egg albumin in
the subplanter region of the right hind paw and edema assessed by mercury
displacement for a period of 0-180 minutes. Anti-inflammatory effect was
significant within 30 minutes of induced edema with inhibition occurring in
three phases of 0-30, 30-60, 60-90. 90-120 to 180 minutes. Inhibition was
highest at the third phase. Crateva adansonii barks showed anti-
inflammatory effect by inhibiting “prostaglandin” synthesis an inflammatory
mediator.
