Derivative spectrophotometric assay methods for dextromethorphane hydrobomide in twelve cough tablets containing single compound as a well as its combination have been performed. Spectrogram of normal spectrophotometry, is a plot of absorbance A against wavelength, (lambda), in derivative technique, the plot is transformed into a plot of dA/dlambda vs lambda for first derivative, and d2A/dlambd…
In order to study the effect of cell defferentiation on its terpenoids content in Curcuma zedoaria plant, GC-MS analysis of the ether extracts from its tissue cultures were performed. The results of the analysis showed that the degree of cell differentiation could influence their terpenoids content. The organ cultures (shoot, roots and plantlet cultures) could produce more terpenoids compared t…
In order to obtain the corresponding data about the interaction between the drug-PT, and the membrane modification, and to observe the probability of the PT usage as the solid dispersion vehicle, the study of the bioavailability of salicylate after acetosal oral administration which was dispersed into the (1:2) mixture of polyaethylene glycol 4000 - tween 80 had been carried out. The capsul dos…
