| antimalarial dihydroisocoumarins produced by geotrichum sp., an endophytic fungus of crassocephalum crepidioides. | three novel dihydroisocoumarin derivatives (1-3) with antimalarial, antituberculous, and antifungal activities have been isolated by bioassay-guided fractionation from an endophytic fungus, geotrichum sp., collected from crassocephalum crepidioides. structures were established as 7-butyl-6,8-dihydroxy-3(r)-pent-11-enylisochroman-1-one (1), 7-but-15-enyl-6,8-dihydroxy-3(r)-pent-11-enylisochroman-1-one (2), and 7-butyl-6,8-dihydroxy-3(r)-pentylisochroman-1-one (3) using spectroscopic data. | 2003 | 12762815 |
| free radical scavenging and hepatoprotective actions of the medicinal herb, crassocephalum crepidioides from the okinawa islands. | free radical scavenging and protective actions against chemically induced hepatotoxicity of crassocephalum crepidioides were investigated. a water extract of c. crepidioides strongly scavenged superoxide anion, hydroxyl radical and also stable radical 1,1-diphenyl-2-picrylhydrazyl. galactosamine (galn, 400 mg/kg) and lipopolysaccharide (lps, 0.5 microg/kg) induced hepatotoxicity of rats as seen by an elevation of serum alanine aminotransferase (alt) and aspartate aminotransferase (ast) and of li ... | 2005 | 15635156 |
| a field-scale study of cadmium phytoremediation in a contaminated agricultural soil at mae sot district, tak province, thailand: (1) determination of cd-hyperaccumulating plants. | the cadmium (cd) phytoremediation capabilities of gynura pseudochina, chromolaena odorata, conyza sumatrensis, crassocephalum crepidioides and nicotiana tabacum were determined by conducting in-situ experiments in a highly cd-contaminated agricultural field at mae sot district, tak province, thailand. most of these five plant species, which are commonly found in thailand, previously demonstrated cd-hyperaccumulating capacities under greenhouse conditions. this study represented an important init ... | 2015 | 25454203 |
| β-cell protection and antidiabetic activities of crassocephalum crepidioides (asteraceae) benth. s. moore extract against alloxan-induced oxidative stress via regulation of apoptosis and reactive oxygen species (ros). | medicinal plants are becoming more popular in the treatment of various diseases because of the adverse effects of the current therapy, especially antioxidant plant components such as phenols and flavonoids have a protective role against oxidative stress-induced degenerative diseases like diabetes. thus, the purpose of this study was to investigate β-cell protection and antidiabetic activities of crassocephalum crepidioides (asteraceae) benth. s. moore. | 2017 | 28356096 |
| antitumor activity and macrophage nitric oxide producing action of medicinal herb, crassocephalum crepidioides. | crassocephalum crepidioides, a plant distributed in okinawa islands, is known in folk medicine; however, its anticancer activity has not been investigated. the aim of this study was to determine the in vitro and in vivo antitumor activities of c. crepidioides on murine sarcoma 180 (s-180) and related molecular mechanisms. | 2012 | 22720874 |
