With 60% ethanol as solvent, only half the amount of harpagoside (and possibly other co-active constituents) is extracted compared to water as solvent [ 42]; therefore, it is of great importance that a confirmatory study provide evidence of effectiveness for the ethanolic extract.
Standard potentials (E°) of Li, K and Tl electrodes in propylene carbonate (PC) have been determined, at 25°, on the basis of the "solvent-independent" half-reaction: Ferricinium+ +e ⇌Ferrocene.
Besides, in the presence of hydrophobic organic solvents, the half-lives of the esterase were much longer than in the absence of the solvents or in the presence of hydrophilic solvents.
It's almost as bad for community radio practitioners who act as the voice of social movements: they are continually harassed or charged with using the airwaves without a licence, and the law has been designed to prevent them from procuring the advertising revenues that might make them even half solvent.
The complex crystallizes in the space group P21/ n with a disordered pentane solvent molecule in half occupancy (Experimental Section and Supporting Information, Table S1).
For determination of overall ER-mediated activity, we replaced the solvent with DMSO in one-half of the crude extract; the second half of the sample was placed on a sulfuric acid-activated silica column and eluted with n-hexane:diethyl ether mixture, evaporated, and redissolved in DMSO (Murk et al. 1997).
This process was optimized at the injection schedule of 1-year steam and a half-year solvent injection, alternatively.
In addition, RD could also complement the information provided by traditional measures such as ASA [2] [5], solvent accessibility [6], [11], half-sphere exposure [26], [27], recursive convex hull (RCH) [28] and residue contact number (CN) [29], [30].
A new, promising solvent exposure measure, called half-sphere-exposure (HSE), has recently been proposed.
Recently, a new promising solvent exposure measure, called half-sphere-exposure (HSE), has been proposed [ 9].
