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.Abstract: Coriandrum sativum (Linn.) which belongs to the family of Apiaceae locally known as ‘Dhania’ in Bangladesh.

Abstract: As age increases older persons may develop sleep problems. These may cause depression, a condition which negatively affects many aspects of older persons’ life. The aim of this study was to assess the relationships between older persons’ sleep problems and depression in Bangladesh. Data were collected from 280 older persons using the Athens Insomnia Scale (AIS-5), and Geriatric Depression Scale (GDS-10). Descriptive and correlational statistics were used to analyze sleep problems and depression data. Results show that sleep problems are significantly and positively related to depression. The identification of intervention programs for the screening of both sleep problems and depression, with a view to reducing the consequences of depression, is recommended.Abstract: As age increases older persons may develop sleep problems.
