Characterization of fats and oils is important in assessing their potential economic uses. This study was carried out to determine and compare the physicochemical characteristics of a commercial oil and solvent extracted oil from the kernels of calabash seeds (Lagenaria siceraria). The range of physicochemical properties are: Solvent extraction recorded a higher yield of (42.3±0.66%) acid value (9.4±1.8 - 8.2±0.5 mgKOH/g of oil), iodine value (4.56±2.6 - 4.46±0.07 mg/100g), saponification value (162.7±4.58 - 159.42±3.68 mgKOH/g), peroxide value (6.0±1.63 - 5.3±2.4 mEq/kg), free fatty acid (10.3±1.76 - 9.89±1.8 % as oleic acid). The low iodine value indicates a high degree of saturation of the fat as well as its non-drying nature.

The physiocochemical properties of Jatropha curcas kernel oils were characterized as potential biodiesel, including oil yield per plant, seed oil content, kernel oil content, acid value, iodine value, saponification value and cetane number. Twenty-five accessions of Jatropha curcas were used for oil content measurement sranging from 21.14 to 40.66 %with a mean value of 32.85% and Kernels oil 48.59 to 60.45 % with a mean value of 56.28 %. The seed index ranged significantly from a seed weight of 45.45 to 64.45 g. Oil yields per plant ranged from 0.44 to 2.85 kg with a mean value of 1.70 kg per plant, respectively. To understand the properties of acid value, iodine value, saponification and cetane number, experimental physio-chemical studies were performed. Since these properties are critical for determining the current oil condition. The current study confirms that accession seeds performed higher than international saponification value, iodine value and cetane number standards may be an important source for meeting potential energy requirements.

Soxhlet extraction of oil from seeds of Vitelleria paradoxa was carried out using n-hexane as the solvent. Standards methods were adopted in the analysis of the physiochemical properties; moisture content, melting point, total ash content, pH, specific gravity, iodine value, saponification value, acid value, free fatty acid value and ester value were all evaluated. The oil recovery rate was good with 32.6% yield, moisture content of 3.1%, melting point of 52oC and pH 5.7. Total ash content was 50.3%, specific gravity of 0.9 g/cm3, iodine value 39 mg/L, saponification value 224.6 mgKOH/g, acid value 59.9 mgKOH/g free fatty acid (FFA) 29.9 mgKOH/L and ester value 164.7 mg/L. The results shows that oil from Vitelleria paradoxa seed holds the potentials for wider applications in foods, cosmetics, pharmaceuticals, lubricants and soap making.

The aim of this work is to study the influence of the physicochemical characteristics of neem seeds, according to their mass and oil content, on the production of biodiesel. After the physical characterization of the seeds and extraction of the oil (triglycerides), biodiesel was produced from crude neem seed oil by transesterification with ethanol in the presence of sodium hydroxide. This study shows that the physicochemical characteristics of these seeds vary according to the origin of the samples. The seeds from Zidim, with a mass average of 200 seeds evaluated at 141.36 g and an almond content of 40.70%, have better characteristics compared to those collected in the city of Maroua, with average values evaluated at 128.00 g and 36.05%, respectively. Almonds have an average lipid content of 53.98 and 56.75% for the Maroua and Zidim samples, respectively. This study also reveals that neem oil, by its physicochemical characteristics, has a satisfactory quality for a valorization in the production of biodiesel. However, its relatively high free fatty acid content is a major drawback, which leads to a low yield of biodiesel, evaluated on average at 89.02%, and requires a desacidification operation to improve this yield. The analysis of biodiesel indicates physicochemical characteristics close and comparable to those of petrodiesel, particularly in terms of calorific value, density, kinematic viscosity, acid value, evaluated at 41.00 MJ/kg, 0.803, 4.42 cSt, and 0.130 mg/g, respectively.

This research work was undertaken to evaluate the physicochemical parameters of oil from the cherry kernel non-irradiated and irradiated at 3 and 6 kGy of gamma irradiation for two storage periods (0 and 12 months). The acid value, peroxide value, thiobarbituric acid reactive substances value, iodine value, saponification value refractive index (peroxide value), and the color parameters of cherry kernel oils were determined. The results indicated that the extracted cherry kernel oils were liquid at room temperature with color varying from light yellow to deep red. The physicochemical properties of cherry kernel oils including acid value, peroxide value, thiobarbituric acid reactive substances, iodine value, saponification value, and refractive index values were 1.19 mg KOH g−1, 9.01 meq2 kg−1, 0.014 mg MDA kg−1, 99.48 KOH g−1 I2 100 g−1, 194.50 mg KOH g−1, and 1.472, respectively. Generally, gamma irradiation doses and storage time increased acid value, peroxide value, thiobarbituric acid reactive substances, and refractive index value of cherry kernel oils, whereas no significant (p > 0.05) change due to irradiation was recorded in iodine value, saponification value, and in color parameter (L*, a*, b*, and ΔE values) of cherry kernel oils. However, the properties of cherry kernel oils revealed that the cherry kernel is a good source of oil which could be used for industrial purposes.

Yashtimadhu ghrita is a single-herbal ghee formulation mentioned in the classical texts of Ayurveda and is indicated in sadya kshatavrana (an acute inflammatory condition or an acute wound associated with trauma). It also minimizes the pain related to the wound. The present study is intended to create a finger print profile of Yastimadhu ghrita through its pharmacognostical identification and the physico-chemical analysis.  The genuineness of the dry specimen of Yashtimadhu (Glycyrrhiza glabra Linn.) was confirmed through organoleptic evaluation and cross-sectional microscopy. Yashtimadhu ghrita was prepared  as per the Sneha paka (preparation of unctuous formulations using ghee, oil etc.) procedure mentioned in Sarngadhara Samhita Madhyama khanda and the standard operative procedures specified in Ayurvedic pharmacopoeia of India. The test result of the finished product shows Acid value 6.7, saponification value 213.4, and Refractive index value1.455 at room temperature, Iodine value 38.7, LOD 0.64. TLC and HPTLC were carried out for the characterization of the plant material in an appropriate solvent system. A total of nine spots were distinguished in 254 nm and five spots in 366 nm during the HPTLC scanning. The Rf value pertaining to the spots were identical in the methanolic extract which indicates the presence of definite constituents in Yashtimadhu ghrita.

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.
