The physico-chemical properties of the extracted oil were studied by the conventional methods. It was observed that Siyal Kanta grown under the soil and climatic condition of Bangladesh contains about 35% of pale yellow coloured oil. The total lipids were fractionated into three major lipid groups, neutral lipids, glycolipid and phospholipids by silicic acid column chromatography. Among the lipids, the neutral lipids were varied from 92.1-92.3%, glycolipid 5.5-5.8% and phospholipid 1.5-1.7% of the total oil of the lipid applied. The oil was also fractionated into mono-, di- and triglyceride by silicic acid column chromatography. The triglycerides were varied from 90.1-90.3%, diglycerides from 2.3-2.8% and monoglycerides from 1.5-1.8%. The saturated and unsaturated fatty acids present in the oil were separated and found to be 14.2-14.5% and 84.2-84.8% respectively depending on the areas in which the plant grows. The fatty acid compositions of the oil were analyzed by Gas Liquid Chromatography (GLC). The major fatty acids found in the oil were oleic acid (23%), linoleic acid (58%), palmetic acid (7%) and ricinoleic acid (10%). Key words: Siyal kanta seed oil; Glyceride; Lipid; Fatty acid.

Oil Extract

This study investigates the physico-chemical and fatty acids composition of crude seed oil extracts of Azadirachta indica . The main objective was to evaluate some biodiesel characteristics of the crude seed oil extract of Azadirachta indica. The procedures of the Association of Official and Analytical Chemist (AOAC) were used for assessment of some physical, biochemical, and fatty acids constituents of the test seed oil extract. The physical properties assayed for indicate that the oil is liquid at room temperature, non-drying, with specific gravity, with flash and melting points of 0.910±0.08 g/cm3, 80±2.10°C and 76±1.60°C respectively. The chemical properties included 66.77±2.55 g/100g (iodine value), 1.465±0.07 (refractive index@ 30°C), 212.96±1.16 mgKOH/g (saponification value), 0.39±0.16 meq/Kg (peroxide value), 4.24±0.12 mgKOH/g (acid value), 2.20±0.12 mm2/s (viscosity value), 56.91±2.19 (cetane number), 39.21±1.11 MJ/kg (calorific value) and 2.13±0.05% w/w (free fatty acids). Fatty acids composition of the crude seed oil of A. indica obtained were linoleic, hexadecanoic, octadecanoic and alpha linolenic acids, with retention time and % composition of 18.2 min and 10.8±0.50%, 22.2 min and 30.01±1.79%, 18.2 min and 59.10±2.22%, and 20.2 min and 0.09±0.02% respectively. The crude seed oil extract clearly presents a potential as a biodiesel substrate for incorporation as a proximate blend in auto-engines. This therefore would necessitate intensive afforestation efforts of the plant species for sustainable utilization.

Chrozophora tinctoria L., usually known as dyer’s Croton, Turnsole or Giradol, has been used in various medicinal and food products for many years. However, no comprehensive research has been undertaken to assess its potential as a new seed oil crop. Therefore, the current study examined the fatty acid composition, physico-chemical properties and antioxidant activity of C. tinctoria seeds, grown in the southwest of Iran. The seed oil content was found to be 26.40%. The extracted oil was analyzed for fatty acid composition using gas chromatography (GC). The results showed that unsaturated fatty acids accounted for almost 91% of the total fatty acids. Linoleic acid was the dominant fatty acid (76.68%), followed by oleic acid (13.99%) and palmitic acid (5.32%). δ-tocopherol was the major tocopherol in the oil, representing 70 mg/100 g oil. The total phenolic content (151.70 mg GAE per 100 g oil) and total flavonoid content (1.17 mg QE oil) were also determined in the extracted oil. The antioxidant activity was measured by a DPPH assay and expressed as 45% of the seed oil. Due to its high oil yield and high unsaturated fatty acid content, C. tinctoria could be regarded as a new source of edible oil.

Seven fatty acids were isolated from pet-ether extract of Nyctanthes arbor-tristis Linn (Seuli) leaves. The relative percentages of the major fatty acids were identified by GLC as palmitic acid (23.88%), linoleic acid (8.95%), stearic acid (47.56%) and oleic acid (5.07%). The yield of the leaves fat was 2.10%. Acid value of seed oil was found to be 76.27 and suggests that this oil is inedible. Physico-chemical characteristic, such as acid value, iodine value, moisture, ash, lignin, crude fibre, fat, protein and carbohydrate of the Seuli leaf were also determined.

Palado (Aglaia sp) is a plant that grows wild in the forest around Mamuju regency of West Sulawesi, Indonesia. This plant is locally known as palado. Palado seeds (Aglaia sp) can be used as a source of vegetable oil because it contains approximately 14.75 % oil, and it has the potential to be used as food ingredients or as raw material for oil production. The purpose of this study was to determine the chemical properties and the composition of fatty acids contained in palado seed oil (Aglaia sp). The employed method involved the use of palado fruit that had been processed to be palado seed and undergoing flouring process. Palado flour was produced by the extraction process by using chloroform solvent with the soxhlet method. The characteristics of the chemical properties in the oil produced were analyzed by using a standard method, including iodine, saponification, and acid values. The analysis of fatty acid composition was conducted by using gas chromatography. The results showed that palado oil extracted with hexane had an iodine value of 15.38 mg/g, saponification value of 190.01 mg KOH/g, and acids value of 1.961 mg KOH/g. The fatty acid composition of the palado seed oil consisted of saturated fatty acids (41.601 %), which included palmitic acid (41.062 %), myristic acid (0.539 %), and unsaturated fatty acids (45.949 %), which included mono-unsaturated fatty acids (MUFA) such as (22.929 %), oleic acid and poly-unsaturated fatty acids (PUFA), which was linoleic acid (23.020 %).

Almonds (Prunus amygdalus) are a rich source of many essential nutrients. However, there is a lack of enough information on almond varieties' biochemical composition, especially at the germination stage. Therefore, this study was conducted to determine the chemical components of the germinating Tunisian almonds. The study included determining the content of oils, proteins, fatty acids, and triglycerides during germination. Results indicated that the oleaginous seeds are rich in oil (55 to 65% of the dry mass) and crude protein (21.825 mg/mL). The dominant polyunsaturated fatty acids are oleic and linoleic acids which represent 64.53% and 24.38%, respectively, while palmitic acid is the most dominant saturated fatty acid with 7.65% of the total fatty acids. Also, the primary molecular types of triglycerides detected by L.C. analysis are triolein (32.3%) and dioleolinolein (24.0%), followed by palmitodiolein (12.5%) and oleodilinolein (12.6%.). The physico-chemical properties study revealed that almond oil remains stable, thus preserving its quality and nutritional value, even during transition from dormancy to germination. On the other hand, we also detected the presence of a lipolytic activity which is maximum on the 3rd day of germination (4.66 mUI). Our results indicate that almond oil plays an important role in human nutrition due to the presence of unsaturated fatty acids, and it is more stable than other oils.

Seed oils have been used for centuries by communities as food, medicine, cosmetic applications, and fuel. Recently, there has been a renewed interest in these nontimber forest products specifically for use in cosmetic formulations. The fatty acid compositions of kernel oil of Heynea trijuga was analyzed by GC-FID. The results showed that the oil content was 37.61 percent (w/w) in seed. Seed oil was rich in unsaturated fatty acids. Important fatty acids present were palmitic acid (22.12%), stearic acid (7.51%), oleic acid (25.20%), and linoleic acid (11.65%).
