Abstract

Seeds are the store house of nutrients for the seedling that will grow from the embryo. The nutrients that are stored depend upon the kind of plant and the family it belongs. Seeds serve several functions for the plants they produce. Some seeds are edible and others are poisonous, non edible. Whether it is an edible seed or not, it is a source of medicine. Hence, the present study was initiated to assess the properties of seeds belonging to Fabaceae both qualitatively and quantitatively. Our results show, that both the seeds were found to contain phyto-chemicals such as carbohydrate, alkaloid, glycoside, steroid, tannin, phenolic compounds, protein, amino acids and fixed oil. The behavior of both seed powders with different chemicals showed positive result for alkaloids, steroids, flavonoids, proteins. The fluorescence study was positive with Phaseolus lunatus and the yield in percentage was also higher for Phaseolus lunatus (22.58) when compared to Abrus precatorius (17.31%). According to our results, the carbohydrate content was found to be high with Abrus precatorius (179.33±1.15mg/g) while, the protein and amino acid content was high (17.41±0.07mg/g, 03.08±0.19 mg/g) with Phaseolus lunatus.
