Abstract: The physicochemical properties, glycerides, lipids and fatty acid compositions of mulberry (tut) seed oil have been studied. It was observed that tut, a shrub grown well under the soil and climatic conditions of Bangladesh contains 31.41% of orange yellow colored oil. The oil was fractionated into mono, di and triglycerides by silicic acid column chromatography. The triglyceride was varied from 90.08-91.05%, diglyceride from 3.25-4.10% and monoglyceride from 1.47-2.05%. The total lipids were fractionated into three major lipid groups, neutral lipids, glycolipids and phospho-lipids by silicic acid column chromatograpy. The neutral lipid ranges from 92.97-93.10%, glycolipids from 2.12-2.43% and phospholipid from 1.85-1.92% of the total oil of the lipid applied. Saturated and unsaturated fatty acids present in the oil were separated and the amount varied from 15.04-16.28% and 74.29-75.86%, respectively, depending on soil conditions of the areas in which the plant grows. The percentage of fatty acid compositions of the oil were analyzed by GLC and found to contain linoleic acid (74.29%), palmitic acid (10.60%), stearic acid (5.61%) and myristic acid (0.07%).Abstract: The physicochemical properties, glycerides, lipids and fatty acid compositions of mulberry (tut) seed oil have been studied.

Abstract: The analysis of proximate and some essential major elements (calcium, magnesium, potassium and sodium) of the leaves of Telfairia occidentalis, Moringa oleifera and Brassica oleracea was carried out using standard methods of food analysis. The result of proximate composition revealed remarkable ash contents of 16.40±0.5 and 11.17±0.2% for leaves of Telfairia occidentalis and Brassica oleracea respectively, indicating that these two vegetable samples are good mineral sources, since ash content of a plant material is an index of total mineral content. High carbohydrate contents led to a corresponding high energy values of 354.20±0.7 kcal/100g (Telfairia occidentalis), 363.60±1.2 kcal/100g (Moringa oleifera) and 319.80±0.7kcal/100g (Brassica oleracea). High potassium concentrations of 742±1.60, 667±3.80 and 1917±1.03mg/100g obtained for the leaves of Telfairia occidentalis, Moringa oleifera and Brassica oleracea respectively also implied that these vegetables could serve as better potassium sources for hypertensive patients. Recorded Nutrient density (ND) of greater than 100% recorded for all the elements revealed that the analysed selected vegetables could serve as alternative source of supplement for these mineral elements.Abstract: The analysis of proximate and some essential major elements (calcium, magnesium, potassium and sodium) of the leaves of Telfairia occidentalis, Moringa oleifera and Brassica oleracea was carried out using standard methods of food analysis.
