Ethanol extracts of 83 plants species belonging to the Asteraceae (Compositae) family, collected in the State of Minas Gerais, Brazil, were tested for larvicidal activity against the mosquito Aedes fluviatilis--Diptera: Culicidae). The extract from Tagetes minuta was the most active with a LC90 of 1.5 mg/l and LC50 of 1.0 mg/l. This plant has been the object of several studies by other groups a...
After screening extensively factors in plant extracts that increase alkaline phosphatase activity, an osteoblastic differentiation marker protein in mouse calvarial osteoblast MC3T3-E1 cells, GnafC derived from Gnaphalium affine, was found to significantly enhance the alkaline phosphatase (ALPase) activity in a synergistic manner with ascorbate. GnafC was a polysaccharaide with an approximate m...
In this study, a new method based on immobilized metal affinity chromatography (IMAC) combined with ultrafiltration-ultra performance liquid chromatography-mass spectrometry (UF-UPLC-MS) was developed for discovering ligands for xanthine oxidase (XO) in Gnaphalium hypoleucum DC., a folk medicine used in China for the treatment of gout. By IMAC, the high flavonoid content of G. hypoleucum could ...
