Lectins are carbohydrate-binding proteins of non-immune origin that agglutinate cells or precipitate glycoconjugates.Based on evolutionary and structural relatedness, seven lectin families have been distinguished, of which legume lectins are the best characterized. Lectins typically constitute a large fraction of the total protein in most leguminous seeds and plant storage tissues where they play an important role in several defense mechanisms. A lectin from the seeds of Indigofera heterantha, member of family leguminosae was isolated, purified, partially characterized and its antimicrobial...

Lectins are proteins or glycoproteins of non immune origin which have a wide distribution in animals, plants, and microorganisms. Their medicinal role extends from simple antimicrobial action to anti- tumour properties.In view of the advancement in understanding the potential medicinal role of the plant lectins, a lectin from the leaves of Prunella vulgaris was isolated, purified, partially characterized and its antimicrobial activity evaluated. The lectin is specific for galactose and N-acetyl-galactosamine The molecular weight of the lectin as determined by SDS-PAGE was 32500 Da and that...

Medicinal plants are being used in traditional treatments to cure variety of diseases from thousands of years. Screening of antimicrobial and antioxidant activities performed on Elsholtzia densa crude extracts which is traditionally used as herb shows that they are endowed with potentially utilizable antimicrobial and free radical scavenging activity. Accordingly, this implies the inhibition of microbial pathogenesis and cellular oxidation that is linked to pathological incidents such as heart disease, aging and cancer. It was seen that the ethylacetate extract showed the maximum inhibitory...
