Abstract
Allium fistulosum L. (Welsh onion leaves) is an important traditional medicinal plant belongs to perennial species originated from Eastern Asia and used for the treatment of colds, abdominal pain, influenza, headache and heart disease. The objective of the study was to investigate the phytochemical constituents and proximate composition of Allium fistulosum L. extracts was determined using standard method. Materials and Methods: Three different extractions were made from A. fistulosum L. using ethanol, hexane, methanol, acetone, ethyl acetate and chloroform. The qualitative, quantitative and proximate composition were performed and compared among the different solvent extracts. Results: The total ash, water soluble ash, acid insoluble ash content and loss on drying of dry powder of Allium fistulosum L. showed high level of total ash (8.235 w/w) water soluble ash (7.13w/w), acid soluble ash (1.225 w/w) and loss of drying (0.81 w/w). The ethanolic extractive value (8.64%) was found more followed by chloroform (7.545%), ethyl acetate (6.47%), methanol (5.63%) and hexane (1.185%) of Allium fistulosum L. The ethanolic extracts contained alkaloids, phenolics, saponins, flavanoids, steroid, tannins and lignin, based on preliminary phytochemical screening. The quantitative assessment contained the total alkaloids contents (TAC) was 22.5 μg, total flavanoids contents (TFC) 25.75 μg and total phenolics contents (TPC) 17.6 μg were obtained. Further study is encouraged on the pharmacological activity of the active components of ethanolic extract that give prospective biological activity. Conclusion: The quantitative determination of Allium fistulosum L. has revealed the presence large quantity of flavanoids amongst all the other phytocompounds. The ethanolic extract of Allium fistulosum L. plant contains pharmacological properties that are known and they can be explored for biological potentials.
