Phytochemical, proximate, and elemental analysis of chia seed (<i>Salvia hispanica</i> L.) from Dawanau grain market, Kano State, Nigeria

Abstract

Plants have shown a lots of importance in the field of phytomedicine, phamacognosy and
herbal sciences, the seed of chia seed (Salvia hispanica) was collected from local farmers at
Dawanau grain market Kano State with the aim of determination of phytochemicals, proximate and elemental Analysis and were identified at the herbarium of plant science department of Bayero University Kano with assertion number (BUKHAN 0539), 250g of the processed seed were macerated in 500 ml of methanol, water, ethyl acetate and hexane for 72hrs. Standard method was followed for qualitative and quantitative phytochemical analysis, proximate and elemental analysis, furthermore thin layer chromatography and Fourier transform infrared microscopic analysis was conducted. The result of the analysis shows that flavonoid and carbohydrate was present throughout the solvents used, while all the proximate and heavy metal analysis were found to be within the limit of EP/WHO 2011 and WHO 1984 with the exception of Manganese. The result of the thin layer Chromatography result has the retention factor and number of spot. The FTIR analysis of the extract reveal that the I.R spectra indicated the present of different functional group such as amine, ketones, carboxylic acid and phenol. Conclusively the plant sample has shown the present of phytochemical substances that are remarkably useful in the field of ethonomedicine.
