A Biosystematic Study of Silphium Integrifolium Michaux ( Compositae ) 1 - 2
Cytological and chromatographic data indicate that Silphium integrifolium Michx. is a rather homogeneous group of plants. Cytological study shows good pairing during meiosis in interspecific and intraspecific hybrids. Two-dimensional paper chromatography indicates that the varieties of S. integrifolium are more similar to each other than they are to two related species, S. asperrimum and 5. spe...
متن کاملExtraction of phytoecdysones with ethanol-modified supercritical CO2
Biologically active polar substance 20-hydroxyecdysone was extracted from roots and leaves of Leuzea carthamoides with ethanol-modified dense carbon dioxide. The effect of operating conditions (pressure 20-27 MPa, temperature 40-60 oC, ethanol concentration in the solvent 4.3-7.1 wt.%, and solvent-to-feed ratio up to 100 g/g) on the extraction rate and the concentration in extract was examined....
