inhibitory effects of natural plants of jeju island on elastase and mmp-1 expression. | in order to search for new active cosmetic ingredients of natural origin, we screened about 60 plants collected from jeju island, which is located in the southernmost part of the republic of korea. we investigated their free radical scavenging activity, elastase inhibition activity, and reduction of mmp-1 mrna expression for the development of anti-aging ingredients as raw materials for use in cosmetics. in the free radical scavenging capacity assay, 12 extracts, including typha orientalis (seed ... | 2007 | 17342265 |
[inhibitory effects of liquor cultured with nelumbo nucifera and nymphaea tetragona on the growth of microcystis aeruginosa]. | the inhibitory effects of liquor cultured with nelumbo nucifera and nymphaea tetragona on the growth of microcystis aeruginosa have been investigated by measuring the cell number and the chlorophyll a content of microcystis aeruginosa of culture in the laboratory. the results showed that the inhibitory effects on the growth of microcystis aeruginosa with different concentration of the liquor cultured with nelumbo nucifera and nymphaea tetragona were dissimilar, and an evident phenomenon appeared ... | 2007 | 18268975 |
synergistic effect and antiquorum sensing activity of nymphaea tetragona (water lily) extract. | salmonellosis is a common and widely distributed food borne disease where salmonella typhimurium is one of the most important etiologic agents. the purpose of this study was to investigate the antimicrobial activity of nymphaea tetragona alone and in combination with antibiotics against s. typhimurium. it also aimed to assess the plant for quorum sensing inhibition (qsi) activity and to identify the bioactive compounds. the antibacterial activities of the extract were assessed using broth microd ... | 2014 | 24895589 |
modulation of quorum sensing-controlled virulence factors by nymphaea tetragona (water lily) extract. | nymphaea tetragona is a widely distributed ornamental species with ethnomedicinal uses in the treatment of diarrhea, dysentery, eruptive fevers, and infections. the anti-infectious activities of this herb have already been assessed to clarify its traditional use as a medicine. | 2015 | 26325430 |
radioprotective effect of geraniin via the inhibition of apoptosis triggered by γ-radiation-induced oxidative stress. | the radioprotective effect of geraniin, a tannin compound isolated from nymphaea tetragona georgi var. (nymphaeaceae), against γ-radiation-induced damage was investigated in chinese hamster lung fibroblast (v79-4) cells. geraniin recovered cell viability detected by mtt test and colony formation assay, which was compromised by γ-radiation, and reduced the γ-radiation-induced apoptosis by the inhibition of loss of the mitochondrial membrane potential. geraniin protected cellular components (lipid ... | 2011 | 20680428 |
