BACKGROUND The continuous emergence of multi-drug-resistant bacteria drastically reduces the efficacy of antibiotic armory and, consequently, increases the frequency of therapeutic failure. The discovery of new antibacterial drugs is an urgent need. The present study reports the antibacterial and antioxidant activities of the methanol extract, fractions and iridoids from Canthium subcordatum, a...

Miang is a kind of traditional fermented tea leaves, widely consumed in northern Thailand as a snack. It contains several kinds of Lactobacilli spp. The aim of this study was to isolate strains of Lactobacillus fermentum from miang and to investigate their antibacterial and antioxidant activities. The agar spot and well assays were used for determination of antibacterial power. The antibacteria...

the current study was assigned to evaluate the total phenol, total flavonoid content (tpc, tfc) and antioxidant properties of extracts from the aerial parts of scrophularia frigida (s. frigida). extracts were also tested by preliminary phytochemical screening as well as cytotoxic activity against artemia salina, mcf-7 (human breast carcinoma) and sw-480 (colon carcinoma) and l-929 (normal) cell...

Seven indigenous medicinal plants, Mallotus philippensis, Pogostemon cablin, Colebrookea oppositifolia, Mussaenda macrophylla, Celosia argentea, Pilea symmeria and Thysanolaena maxima, have been investigated for their antimicrobial activity and antioxidant activity. The ethanol extract of these medicinal plants were subjected to evaluate their antibacterial properties and their antioxidant pote...

BACKGROUND The threat posed by drug-resistant pathogens has resulted in the increasing momentum in research and development for effective alternative medications. The antioxidant and antibacterial properties of phytochemical extracts makes them attractive alternative complementary medicines. Therefore, this study evaluated the phytochemical constituents of Melaleuca cajuputi flower and leaf (GF...

The present study was undertaken to explore the possible biochemical activities of Hyaenanche globosa Lamb. and its compounds. Two different extracts (ethanol and dichloromethane) of four different parts (leaves, root, stem, and fruits) of H. globosa were evaluated for their possible antibacterial, antityrosinase, and anticancer (cytotoxicity) properties. Two pure compounds were isolated using ...
