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-dimethyl-myrtenyl 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.
Highlights
Essential oils are natural, complex volatile compound mixtures characterized by a strong odour
The yield percentage of essential oil was determined using the formula described by Rao et at [25] where the amount of essential oil recovered (g) was determined by weighing the oil after moisture was removed
The physicochemical analysis is performed according to the procedure described by Atti-Santos et al [27] by using five parameters: specific gravity (SG), optical rotation (OR), refractive index (RI), solubility in ethanol (SE), and residue on evaporation (RE)
Summary
Complex volatile compound mixtures characterized by a strong odour. Essential oils are composed mainly of terpenoids, including monoterpenes and sesquiterpenes, their oxygenated derivatives and a variety of molecules such as aliphatic hydrocarbons, acids, alcohols, aldehydes, acyclic esters or lactones, and exceptionally nitrogen and sulphur containing compounds and coumarins. Known for their antimicrobial medicinal properties and their fragrance, they are invariably used in preservation of foods and asantimicrobial, analgesic, sedative, anti-inflammatory, spasmolytic and local anesthetic remedies [1, 2].
