Abstract

Blumea lacera (Asteraceae) is one of the common Rabi weeds of India. It is an annual herb, with a strong odor of turpentine. These secondary metabolites are those metabolites which are often produced in a phase of subsequent to growth, have no function in growth, are produced by certain restricted taxonomic groups of microorganisms, have unusual chemicals structures, and are often formed as mixtures of closely related members of a chemical family. The present study focuses on the qualitative and quantative estimation of secondary metabolites from Blumea lacera leaf and stem using different solvents such as aqueous, methanol, ethanol, acetone, petroleum ether, chloroform. Leaf extracts and stem extracts were revealed the presence of various secondary metabolites such as phenol, tannins, flavonoids, alkaline, saponins, glycosides, steroids, terpenoids and alkaloids. Compared to both leaf and stem various extracts in methanolic extract of leaf phenolic (9.0 mg/g), flavonoids (6.50 mg/g) and alkaloids (3.65 mg/g) compounds were present in higher amount. In petroleum ether extract of stem tannin (2.41 mg/g) was present highest amount. Plant secondary metabolites are unique sources for pharmaceuticals, food additives, flavors, and industrially important biochemicals. The plant is described in Ayurveda as astringent, anti-inflammatory, styptic, ophthalmic, digestive, anthelminthic, liver tonic, expectorant, febrifuge, antipyretic, diuretic, deobstruant, and stimulant. The plant extract possess anti-diarrhea, antimicrobial, antiviral, anxiolytic, antiatherothrombosis, membrane stabilizing, anticancer activities and alpha-amylase inhibitory activities.
