Abstract
The methanol extracts of all the various parts of Morinda lucida were studied in vivo for anti-peroxidative, protective
and ameliorative effects against carbon tetrachloride (CCl4) induced hepatocellular injury. Thiobarbituric acid reactive
substances (TBARS) concentration taken as a measure of lipid peroxidation showed pre-treatment with the parts each
(100 mg/kg) conferring anti-peroxidative effect while the leaf and bark extracts showed anti-peroxidative effect in the
post-treatment test. Markers of hepatic damage viz: AST, ALT, total and conjugated bilirubin also showed signifcant
protection and amelioration against CCl
4
-induced liver damage. Lipid profle studies like TG, TC, LDL and HDL
showed no statistical difference among the pre-treatment groups and the ‘normal control’ except in the ‘Root+CCl
4
’
or ‘Leaf+CCl
4
’ groups which also showed no difference statistically from the ‘CCl
4
only’ group. In the post-treatment
(ameliorative) tests also, no statistical difference was found among the groups compared with the ‘normal control’
except the ‘CCl
4
+
Root’ and ‘CCl
4
+
Leaf’ groups which bore no statistical difference from the ‘CCl
4
only’ group, as
per LDL and HDL respectively. Findings here show the anti-peroxidative and protective properties of Morinda lucida
comparable to Vitamins C and E, and ameliorative properties comparable to Silymarin against liver injury. These could
possibly be reasons supporting its application in folkloric medicine.

Introduction
Reactive oxygen species (ROS) are major sources of primary
catalysts that initiate oxidation in vivo and in vitro which creates
oxidative stress resulting in numerous diseases and disorders [1,2]
such as cancer [3], cardiovascular disease [4], neural disorders [5],
Alzheimer’s disease [6] mild congnitive impairment [7], Parkinsons
disease [8], alcohol induced liver disease [9], ulcerative colitis [10],
ageing [11] and atherosclerosis [12].
Te extreme toxicity of oxygen is related to its high capability of
generating free radicals which in turn destroys many major biological
molecules. Tey can attack lipids and proteins and destroy membranes.
Oxidized cellular thiols abstract hydrogen atoms from unsaturated fatty
acids to initiate the peroxidation of membrane lipids [13]. A potent
scavenger of these ROS could therefore serve as possible preventive
intervention for free radical-mediated diseases [14].
Today, the search for natural compounds and other preparations
of plant origin that can be used to prevent or mitigate maladies have
been intensifed. For instance, some medicinal and food plants such as
Moringa oleifera [15], Khaya senegalensis [16], Syzygium aromaticum
[17], Hibiscus esculentus [18], Canarium schweinfurthii [15] have
been demonstrated not only to contain phytochemicals with strong
antioxidant capacity, but possess diverse powerful medicinal properties.
Morinda lucida Benth, a Rubiaceae, is known commonly as
‘brimestone tree’ (English), ‘Arbre à soufre’ (French), and ‘Moindo’
(Polish). In Nigeria, it is called ‘oruwo’ or ‘erewo’ (Yoruba), ‘nfa’ or
‘Ezeogu’ (Igbo), Idonzakara (Hausa),‘ogele’ (Igala), among other many
diferent indigenous tribal names, while in other African countries it
is called ‘Uhon’ (Ivory Coast) and ‘hojologbo’ (Sierra Leone) [19-21].
It grows in many African countries and it is widely used as a medicine
in West Africa. Te plant is generally used as ingredients of fever
teas, which are usually taken, for the traditional treatment of malaria
[22]. Te decoction of the stem bark has been reportedly used for the
treatment of severe jaundice [23].
Tis study was thus designed to evaluate the antioxidant efect
of the diferent parts of Morinda lucida and to determine the
hepatoprotective/hepatocurative efects of the extract of the diferent
parts of Morinda lucida on the integrity of the liver and associate
disorders like hyperlipidemia and hyperbilirubinaemia.
Materials and Methods
Chemicals and reagents
All chemicals and reagents (of analytical grade) were obtained
from BioVision Inc. (Milpitas, USA), Sigma Aldrich (Germany) or
RANDOX Laboratories Randox
®
Ltd. (Ardmore, United Kingdom).
Experimental animals
Male albino rats of Wistar strain weighing between 180-280 g were
used. Tey were obtained from Afol farms, Jos, Plateau state and
housed in Bingham University Animal facility. Tey were allowed to
acclimatize for at least two weeks under the laboratory condition before
the experiment was commenced. Except where and when applicable,
animal were maintained on standard regular rodent pellet for rats
procured from Vital Feeds depot, Gizzard plaza, Mararaba, Nasarawa
State. All other protocols for animal management were observed in
compliance with the general guidelines for animal experimentation.
Collection and authentication of plant sample
Te diferent parts of Morinda lucida plant were collected from Idah
Local Government Area of Kogi State. Tey were compressed in a plant
press and sent to the Herbarum Unit of the Department of Biological
