“…Essential oil was obtained by HD for 3 h, using 50 g of plant material in a Clevenger-type apparatus (Rao, Kaul, Syamasundar, & Ramesh, 2005). SFE extracts were obtained from 10 g of plant material using an extraction apparatus with a fixed tubular extractor 9.4 cm in height and 2.13 cm internal diameter, as described by Esquível and Bernardo-Gil (1993).…”

Abstract:Coriandrum sativum (Linn.) which belongs to the family of Apiaceae locally known as 'Dhania' in Bangladesh.In this study essential oil of the three varieties of Dhania from of Brahmanbaria, Faridpur and Radhuni were investigated by GC-MS. Total four chemical constituents were found by gas chromatography and mass spectrometry (GC-MS) analysis from the essential oil of Brahmanbaria Dhania. The oil contained alpha-methyl-alpha-[4-methyl-3-pentenyl]oxiranemethanol; 1,6-octadien-3-ol; 3,7-dimethyl acetate; 2,6-octadien-1-ol; 3,7-dimethyl acetate. Total three chemical constituents were found by gas chromatography and mass spectrometry (GC-MS) analysis from the essential oil of Faridpur Dhania. The oil contained alpha-methyl-alpha-[4-methyl-3-pentenyl]oxiranemethanol; 1,6-octadien-3-ol; 2,6-Octadien-1-ol; 3,7-dimethylacetate. On the other hand total, five chemical constituents were found in the Radhuni Dhania. The oil contained 5-ethenyltetrahydro-alpha-5-trimethyl-cis-2-furanmethanol; alpha-methyl-alpha- [4-methyl-3-pentenyl]oxiranemethanol; 1,6-Octadien-3-ol; 3,7-dimethylmyrtenyl acetate; 2,6-octadien-1-ol; 3,7-dimethyl-acetate. The main objective of the present study was focused on identification and quantification of chemical constituents present in the essential oil of Coriandrum sativum Linn by GC-MS methods.

“…The distillation flask of 500 ml contained water about 2/3 of its volume and 50 gm of the powder.The operation proceeded by heating the flask at 100˚ C, heat was applied to the flask and the volatile oil was carried with the steam to a cold condenser, the lighter oil rises to the top of the separator. The essential oils collected was dried over anhydrous sodium sulphate, weighed and stored in a sealed vial dark colored at 4˚ C. The yield percentage of essential oil was determined using the formula described by Rao et al [11].…”

This study was conducted with the aim to extract and purify the essential oil containing terpenes from the dried seeds of nutmeg myristica fragrans available in Iraqi markets.The essential oil was extracted by steam distillation method with a yield of 4.7 -7.5 gm / 100 gm, and the resultant oil was subjected to sensory and physical evaluation. It has a special spicy odor, slightly pungent taste, colorless to pale yellow in color, not dissolved in water but dissolved in organic solvents like ethanol, hexane, chloroform and ether. The specific gravity, refractive index and optical rotation were (0.890 gm / ml), (1.4822) and (+22˚), respectively. Gas chromatography is used for the quality and quantity evaluation of the essential oil constituents which revealed the presence of 49 volatile compounds. The methanolic extract obtained by reflux the seeds powder with 70% methanol in soxhlet apparatus and yield 12.8%. The extract was subjected to phytochemical detection which confirms the presense of alkaloids, terpenes, flavonoids, glycosides, tannins and resins, with the exception of saponins and coumarines which gave negative tests. Myristicin was purified from the methanolic extract of nutmeg dried seeds, which were detected in the essential oil by TLC and vanillin-H2SO4 reagent. The purified myristicin was obtained after the application of adsorption chromatography on silica gel column and detected on T.L.C. plate with standard myristicin.Both the essential oil and purified myristicin were subjected to gas chromatography which showed the presence of myristicin in the oil in a concentration of 6%.
