Discovery of a Potent Anti-Yeast Triterpenoid Saponin, Clematoside-S from Urena lobata L.
Urena lobata has been used as a traditional medicinal plant in India and China. In this study, we investigated the antimicrobial activity and isolated the active compound from the leaves of U. lobata. The 80% ethanol extract from U. lobata leaves showed an effective anti-yeast activity against Saccharomyces cerevisiae (S. cerevisiae) strains. Using a combination of chromatographic methods, (-)-...
متن کاملInfluence of Environmental Factors on the Germination of Urena lobata L. and Its Response to Herbicides
Urena lobata is becoming a noxious and invasive weed in rangelands, pastures, and undisturbed areas in the Philippines. This study determined the effects of seed scarification, light, salt and water stress, amount of rice residue, and seed burial depth on seed germination and emergence of U. lobata; and evaluated the weed's response to post-emergence herbicides. Germination was stimulated by bo...
متن کاملThe Antibacterial Effect of Urena Lobata L. Fromv Guangxi on Mice with Staphylococcus Aureus Pneumonia
BACKGROUND Alcohol extract from the root of Urena lobata L. (ULL) had broad spectrum antimicrobial activity. Studies in vitro have sho that ULL aqueous extract has antibacterial effect on S. aureusis, and the combination therapy of the ULL aqueous extract with cefazolin sodium showed additive effect. MATERIALS AND METHODS The mice underwent nasal inhalation with S. aureus, a subset of mice we...
متن کاملAntioxidant and Cytotoxic Activities of Methanol Extract of Urena lobata (L) Leaves
The methanol extract of leaves of Urena lobata (L) (Malvaceae) has been selected to determine the antioxidant and cytotoxic potentials. The crude extract were tested for in vitro free radical scavenging assays such as 1, 1 diphenyl-2-picryl-hydrazyl (DPPH). Total phenolic and flavonoids content of U. lobata were analyzed. The sample effectively scavenged free radical at all different concentrat...
متن کاملANTIOXIDANT POTENTIAL OF Sida retusa, Urena lobata AND Triumfetta rhomboidea
The methanolic extract of Sida retusa Linn.(Malvaceae),Urena lobata Linn.(Malvaceae)and Triumfetta rhomboidea Jacq.(Teliaceae) roots were found to inhibit lipid peroxidation, scavenge hydroxyl and superoxide radicals in vitro. The quantity of S.retusa root extract required for 50% inhibition of lipid peroxidation, scavenging hydroxyl radical and superoxide radical was 1130.24 ug/ml respectively...
