The pulp of Dacryodes edulis G.Don which is rich in
oils is commonly consumed in Nigeria when in season. The effect of diet supplementation
with edulis fruit pulp oil on body lipid parameters was evaluated in male wistar
albino rats. D. edulis oil was extracted in n-hexane. The test diet was
compounded using the oil extract (10%), whereas the control animals were kept
on control diet formulated with groundnut oil (10%). After six weeks, the animals
were anaesthetized with chloroform and blood samples collected through cardiac
puncture for the determination of serum lipid profile. Results revealed that
D. edulis fruit pulp oil did not cause any significant (p>0.05) alterations
in serum total cholesterol, LDL-cholesterol and triacylglycerol. The total amount
of lipids present in the serum was increased by 33.3%, whereas the quantity
of liver lipids decreased by the same factor (33.3%). Insignificant (p>0.05)
increases in the weights (g 100 g-1 BW) of the liver (2.91±0.17
to 3.38±0.25), kidney (0.36±0.06 to 0.40±0.02) and heart
(0.32±0.02 to 0.33±0.04) were observed in the test group. No significant
change (p>0.05) in the average body weight of the test animals was recorded.
HPLC analysis of D. edulis oil showed that it contained palmitic acid
(48.7%), linoleic acid (28.6%),oleic acid (12.9%), stearic acid (5.0%), lauric
acid (2.2%), linolenic acid (1.7%) and myristic acid (0.9%). The peroxide value
of the oil was 0.00. Prolonged intake of D. edulis fruit pulp oil may
induce adverse effects on the body organs, even though the body lipid profile
remains unaltered. |

Oil was extracted from Moringa oleifera Lam (Moringaceae) seeds collected from Enugu, South-East Nigeria and evaluate its physico-chemical and antioxidant properties in comparism to palm oil. M. oleifera seeds gave oil yield of 41.47%. Refractive index, melting point (oC) and acid value (mg KOH g-1) of M. oleifera oil were 1.471±0.00, 28±0.00, 3.80±0.28 while palm oil had 1.473±0.00, 31±0.00, 6.20±0.35 respectively. Similarly, iodine (I2 100 g-1), saponification (mg KOH g-1) and peroxide (mMol kg-1) values obtained for M. oleifera oil were 85.30±0.25, 171.90±0.56 and 8.10±0.07 whereas palm oil had 34.70±0.13, 210.50±0.00 and 13.40±0.28 respectively. Total phenol (mg Gallic Acid Equivalent g-1), total flavonoids (mg Rutin Equivalent g-1) and total antioxidant capacity (mg Ascorbic Acid Equivalent g-1) were 40.17±0.01, 18.24±0.01, 37.94±0.02 for M. oleifera oil and 62.32±0.04, 33.13±0.03, 68.27±0.02 for palm oil respectively. M. oleifera oil and palm oil showed a concentration dependent DPPH free radical scavenging and reducing power capabilities. This study has shown that Moringa Oleifera gave high oil yield, which has good antioxidant capacity with potential for industrial, nutritional and health applications, therefore large scale cultivation of this economic plant could be used as poverty alleviation strategy in Nigeria. |
