The desert date seeds from two different locations were collected, washed, decocted, dried, and pulverized. The seed oil was extracted using soxhlet apparatus with n- hexane as solvent. The percentage yield of the extracted oil was found to be 40.5% and 42%. While the physicochemical analysis of the seeds oil were conducted using standard procedures with the following results; specific density 0.98g/cm3and 0.87g/cm3, saponification value 134mgKOH/g and 136mgKOH/g peroxide value 38meq/kg and 36meq/kg, acid value 12.6mgKOH/g and 12.5mgKOH/g free fatty acid value 12.7mgKOH/g and 12.5mgKOH/g. These results indicate that Desert date seed oil have almost the same physiochemical properties and could be a rich source of oil for industrial and domestic purposes if exploited richly.

Significant Attention

Biodiesel is a promising alternative fuel and has gained significant attention due to the predicted depletion of conventional fossil fuels and environmental concerns. This study aims to produce biodiesel from ogbono seed oil (using 98 ml methanol and 2g potassium hydroxide (KOH) as a catalyst) via transesterification process and to determine the physiochemical properties of the biodiesel produced. The physiochemical properties of the feedstock (extracted ogbono seed oil) were also determined before the transesterification process. The physiochemical properties of the produced biodiesel showed that it has a density of 0.5±0.00 g/cm3, pour point of 2.0±0, saponification value of 58.90±0.06 mg KOH/g, ester value of 98.0±0.5% (m/m), iodine value of 26.64±0.15gI2/100g, acid value of 0.28±0.05 mgKOH/g, moisture value of 0.0006 ±0.0% and trace amounts of ash content. The results of the physiochemical properties of the produced biodiesel agree with ASTM-D6751 and EN 14214 standard. Thus, it was concluded that ogbono seed oil is an excellent feedstock for biodiesel production via base catalyzed transesterification process

Important Medicinal Plant

Aloe ferox is an important medicinal plant in Southern Africa whose seeds could be useful as a source of oil. The fatty acid composition of A. ferox seed oil was determined using gas chromatography. The physicochemical properties of the oil were analysed using standard methods. The seeds yielded 19.4% of a light textured oil using the Blight and Dyer's method and 12.3% using the Soxhlet extraction method. The saponification value of the seed oil was 241.9 mg KOH/g and the peroxide value was 8.9 meq/kg. The acid value of the seed oil was 51.5 mg KOH/g (25.9% free fatty acids). The major fatty acids found in the seed oil were linoleic acid (71.8%), oleic acid (12.0%), palmitic acid (11.2%) and stearic acid (2.9%). The results obtained suggest that as A. ferox seed oil is high in linoleic acid, it could be potentially exploited in the cosmetic and pharmaceutical industries.

Introduction: Elaeis guinenesis is a perennial monocot belonging to the family Arecaceae. It is the source of the oil commonly called African palm oil or macaw fat which in traditional medicine has many uses Aim: This study is focused on the pharmacognostic screening of oil of Elaeis guineensis, and its antidotal effect on cyanide poisoning. Method: The extracted oil was subjected to various screening technique in order to determine its quality, purity and chemical constituents. The oil was macroscopically examined; acute toxicity test of Elaeis guineensis oil was carried out on rats. The oil was subjected to heating to determine the moisture content. Phytochemical analysis was also carried out on the palm oil extract. The physicochemical analysis was carried to determine the acid value, saponification value, ester value, hydroxyl value and iodine value. The Ld50 for the pure cyanide was carried out on the rats using “Up and Down” method. The antidotal study of Elaeis guineensis oil was carried out on the rats. Result: Macroscopic evaluation showed, the oil was in fresh condition, smooth texture, bright red colour, characteristic taste, oily appearance and a characterictic smell. The Phytochemical analysis showed the presence of flavonoids, phenols, tannins, saponnins, alkaloids, steroids and terpenoids. The physicochemical analysis showed that the oil has an acid value of 31.2, Saponification value of 194.8, Ester value 163.54, Peroxide value of 18.0, Hydroxyl Percentage of 2.07% and Free Fatty Acid of 3.65. The moisture content was calculated to be 0.2%. For the acute toxicity test on the oil using Lorkes method no death was recorded. The LD50 of the cyanide carried out on the rats showed that the lethal dose of cyanide is 5 mg/kg. The antidotal effect of Elaeis guineensis oil showed the absence of death on the group given oil extract alone and the groups that were poisoned and given the oil (antidote) within 4 minutes. Deaths were recorded for the groups that were administered antidotes after 8 minutes. Conclusion: Elaeis guineensis oil has counteracting effect on cyanide poisoning if administered within four minutes of cyanide ingestion.

Due to the high demand for vegetable oil by soap industries, the quest for alternative raw material is on the increase. In this study, vegetable oil was extracted from the underutilise seeds of Lagenaria siceraria using n-hexane; The Physico-chemical properties of the oil were analysed: iodine value 65 Ig/100 g, acid value 2.50 mg/KOH/g, saponification value 256 mgKOH/g, pH 6.20, specific gravity 0.902, the refractive index of 1.47 and oil yield 52%. The properties of the oil were compared with oil extracted from other sources. The properties of the oil suggest it can use for both commercial and industrial purposes. The extracted oil was then used to prepared soap and its properties were compared with the properties of soaps prepared from other oils. The physicochemical parameters of the prepared soaps which include foam height, hardness, pH and cleansing power were evaluated. The soap made from Lagenaria siceraria seeds oil has foam height of 2.0 cm lower than palm kernel oil (2.1 cm) and higher than soya beans (0.55 cm). Soap made from Lagenaria siceraria seed oil has an appreciable degree of hardness and good cleansing power compared to soaps prepared from other oils. The pH of all the soaps prepared is within the standard of the regulating agency in Nigeria. From the result obtained, it shows the underutilised Lagenaria siceraria seed oil can use as an alternative raw material in the commercial production of soap.

Citrullus lanatus (watermelon) and Sesamum indicum (sesame) are edible plants that provide a lot of nutritional benefits to man; despite their wide consumption and benefits, their seed oils remain underutilized. Seed oils from these plants found in south-western Nigeria were analyzed for their physico-chemical properties. Oil was extracted from the seeds using Soxhlet apparatus and n-hexane as the solvent; physico-chemical properties were determined using standard analytical procedures. Watermelon seed oil had a golden brown colour while sesame seed oil had a carton brown colour; they had saponification values of 258.99 mgKOH/g and 261.34 mgKOH/g respectively. Acid value ranged from 2.13 – 2.51 mgKOH/g; iodine value of 39.7 - 42.3 gI2/100g and peroxide value of 1.39 – 2.43 meqKOH/g was determined in the seed oils. Oils from these seeds have numerous domestic and industrial potentials such as cooking, frying, production of soaps, and cosmetics to mention a few.

The Pithraj seed has been collected from Gazipur district, Bangladesh. The oil from the seed was extracted by using Soxhlet apparatus using petroleum ether extraction method. Maximum yield of oil was found to be 50 % when the process was carried out for 2.5 hours. The physicochemical properties of the extracted oil were studied. The properties of the oil reveal that the oil corresponds to diesel except acid value and sulphur content. The optimum conditions of the transesterification of the oil was 40% ethanol and 0.45% KOH at 75 0C for 1.5 hours. The optimum yield was more than 95 %.Bangladesh J. Sci. Ind.
