Physiochemical and proximate analysis of Carum carvi. L.

Abstract

Carum carvi. L. was used traditionally in different populations for many medical complains. The seeds are used for culinary purposes and medicinal treatment. The study was aimed to investigate the proximate analysis of Carum carvi and physiochemical properties of seeds oil. The oil was extraction by petroleum ether (60 to 80°C) using a Soxhlet apparatus. Carum carvi. L. seeds oil showed 4.5% yield of fixed oil. Some of proximate analysis of seeds such as ach, fatty acid, fiber, moisture, protein and carbohydrate were given (9.29 ± 0.52, 1.67 ± 0.16, 46.85 ± 0.49, 3.205 ± 0.021, 31.12 ± 0.46 and 7.87 ± 0.67, respectively). The physico-chemical properties of the extracted fixed oil such as density, refractive index, viscosity, color, acid value, peroxide value, saponification value, un saponification matter and iodine value were given (35.133 ± 0.208, 0.916 ± 0.02, 56.947 ± 0.002, 1.465 ± 0.002, 0.63 ± 1.14, 98.737 ± 0.78, 188.303 ± 1.38, 3.01 ± 0.47 and 4.45 ± 0.48, respectively). It was concluded that physico-chemical parameters were analyzed can be used to determine the quality of fixed oils.
