Biochemical compositions and antibacterial activities of Lantana camara plants with yellow, lavender, red and white flowers

Abstract

Here we report the biochemical composition and antibacterial activities of the leaves and flowers of four Lantana camara (Verbanaceae) plants with yellow, lavender, red, and white flowers. Three out of the four plants showed almost similar carbohydrates and lipid compositions. The levels of carbohydrates (mg/g dry weight) in the flowers were comparatively higher than in the leaves and the lipids content was relatively higher in the leaves except L. camara lavender and white. In lavender L. camara the amount of the total carbohydrates was very low. Proteins extracted from the leaves and flowers were subjected to electrophoresis. Electrophoresis of leaf proteins revealed similarity among L. camara yellow, red, and white flowers while that of flowers proteins showed similarity between L. camara yellow, lavender, red, and white. Extracts of leaves and flowers obtained with ethyl acetate were studied for antibacterial activities. Leaf and flower ethyl acetate extracts exhibited considerable antibacterial activities against the bacteria used where the value of zone of inhibition ranged from 10-21 and 9-15 mm, respectively. For flower and leaf ethyl acetate extracts, the zone of inhibition (mm) measured ranged from 10-21 and 9-15 mm, respectively. Thus, the study of the biochemical parameters viz., lipids, carbohydrates and proteins has revealed similarity among the four different L camara. However, antibacterial activities vary from one L. camara to the other and also according to the type of tissue used.

Phenolic acid content, antioxidant properties, and antibacterial potential of flowers and fruits from selected Pakistani indigenous medicinal plants

“…Most of them showed IC 50 = 50.0 µg, which exhibited weak antibacterial effect. Our findings are in good agreement with the antibacterial potential of extracts of both parts of L. camara and J. adhatoda against different strains of bacteria 12,25,26 .…”

Phytochemical screening, antioxidants and antimicrobial potential of Lantana camara in different solvents

“…Lantadenes which present in all L. camara is believed to be responsible for almost all the biological activities. In addition, other secondary metabolites such as alkaloids, terpenoids, and phenolics could be held partially responsible for some of these biological activities [32] .…”

“…The samples were prepared by dissolving 12 mg extract in 1 mL of dimethyl sulfoxide. Culture media was prepared by dissolving 6.5 g of Sabouraud dextrose agar (MERCK) per 100 mL distilled water (pH 5.6).…”

“…Extracts from the leaves exhibit antimicrobial, insecticidal and nematicidal activity and also contain verbascoside, which possesses antimicrobial, immunosuppressive and antitumor activities [8] . Several previous reports have described antifungal, anti proliferative and antimicrobial activities of L. camara [9][10][11][12][13] . The present study aims to investigate the phytochemicals, free radical scavanging activities and antimicrobial potential of leaves extract of the commonly used medicinal plant L. camara.…”
