The oil obtained by the hydro-distillation method from the fresh leaves and stems of Anethum sowa L. (Dill) herb was analyzed by GC-MS. Twenty compounds were isolated and identified. The major constituents were apiole (25.39%), o-cymene (15.25%), α-thujene (14.84%), β-phellandrene (7.17%), 6,6-dimethyl-2-(3-oxobutyl) bicyclo(3.1.1) heptan-3-one (6.90%), exo-2-hydroxycineol (5.03%), limonene (4.13%), 3-isopropyl-4-methyl-1-pentyn-3-ol (2.89%), myristicine (2.46%) and dihydroumbellulone (2.14%).

Anethum sowa L. (Dill) seeds were investigated to determine the fatty acid composition and proximate analyses. The seeds contain 9.36 % fatty oil. The saturated and unsaturated fatty acids contributed 6.22% and 93.78% respectively of the oil. The per cent composition of the extracted oil was identified by Gas Liquid Chromatography (GLC). Among the six fatty acids identified from this study oleic acid contributed the highest proportion (87.10%), where as, linolenic, palmitic, stearic, behenic and arachidic all together contributed the rest (12.90%). Proximate analyses showed that A. sowa. seeds are good source of dietary fibre. Overall Dill seeds oil can be considered as a good source of oleic acid.

Anethum sowa L. (Dill) were collected from different places of Bangladesh and subjected to quantitative estimation of the elements present in roots of the herb. The elemental analyses were done by XRF (PW 2404 PANAlytical) method. The maximum percentage (%) of the elements found in the root samples were: 24.71, 24.43, 10.30, 9.21, 5.16, 5.11, 3.72, 3.46, 3.08, 2.36, 0.32 and 0.16 for K, Ca, Si, Na, Cl, Mg, Al, S, P, Fe, Ti and Mn respectively. Rb, Sr and Zr were present in small amount and Ni, Cu, Zn, Y and Ba were present in trace amount. However Co, Pb, As and Hg were not found in any of the samples under investigation. This analyses may be helpful for the use of Anethum sowa L. root in pharmaceutical preparation and in ayurvedic form of medicine.

Anethum sowa L. (Dill) stem portions were analyzed for its macro and micro elemental concentration by XRF spectrometry collected from different places of Bangladesh. The plants were collected when those were 35 cm in height i.e. within 40-45 days of sowing. Results of proximate analyses showed that the stem parts contained highest level of moisture (93.67), ash (1.62) and dry matter (30.77%) on fresh weight basis (g/100g). The highest level of mineral contents were Ca(478.50±6.22), K(336.65±3.26), Cl(153.92±3.26), Na(114.86±1.38), S(96.65±1.76), Mg(63.96±1.15), P(49.41±0.74), Al(41.75±0.71), Fe(34.57±1.33), Si(31.03±0.18), Ni (11.98±0.22) and Ti (3.75±0.28) in mg/100g on fresh weight basis. Cu, Sr, Rb, Zn, Ba and Zr were present in small amount and Y, Cu and Mn were present in trace amount. However, the toxic elements like Co, Pb, As and Hg were not found in the present study. Presence of higher amounts of mineral contents in the stem parts could potentially be consumed as supplement as human diets or livestock feed as well as pharmaceutical preparation.
