Study of Flavonoid and Phenol contents and phytochemical screening of weed plants

Plant-derived foods play an essential function in human nutrition and major source of substances with biological 
activity, including vitamins, dietary fiber, antioxidants, and chemicals that decrease cholesterol. The nutritional 
value of plants remains unclear despite a wealth of data on the subject. Historical perspective on the importance of 
various plant nutrients and health-promoting substances. Eragrostis cilianensis (All.) Vignolo ex Janch., Senna 
occidentalis (L.) Link, Dactyloctenium aegyptium (L.) Willd were the test plants of the current study's 
phytochemical screening. These weeds responded favourable to the presence of secondary metabolites such as 
flavonoids, phenol, proteins, carbohydrates, etc., according to quantitative study of flavonoid and phenol techniques. 
These metabolites are important for the plant, but they also define the nutritional quality of the plant. This suggests 
that they are suitable for usage as herbal ingredients. The secondary plant metabolites and the techniques used to 
analyse them are the focus of this piece of content.
