An analytical chromatographic method for determination of total
benzalkonium chloride in eye drops preparations samples containing
gentamicin sulphate, tobramicin and viscous eye drops samples containing
fusidic acid has been developed.
Phenol derivatives have been reacted with aryl halides under
heterogeneous basic catalyst (Amberlyst-21) using 5 mol% Cu(I)
Complex as catalyst, [CuClPPh3]4. The typical reaction has been
performed between p-cresol and bromobenzene. This reaction
is
achieved in o-xylene as solvent. However, the catalyst complex
does not dissolve in toluene rather it acts as heterogeneous catalyst.
Therefore, it is filtrated at the end of the reaction and reused several
times. Accordingly, new compounds were prepared by reacting one
of the bromoaryl derivatives with paracetamol. It is anticipated that
the synthesized compounds may have pharmaceutical application as
non-steroidial anti-inflammatory drugs (NSAIDs).
In this study, we talked about the importance of vitamins as nutritional supplements or medicinal substances and their vital function in the body as enzymatic complements of some vital reactions in the body and diseases caused by a vitamin deficiency
The microbiological limits are considered to be one of the quality
criteria that affect pharmaceutical. Herbal drug medicine is of some
specialty since their raw material contains a high bioburden.
According to pharmacopoeia, Herbal drugs are main
ly whole,
fragmented or cut, plants, parts of plants, algae, fungi, lichen in an
unprocessed state, usually in dried form but sometimes fresh.
The Reaction of Glycerol carried out with tow aryl halides
under basic conditions (K2CO3) using 5 mol% of Pd(II)Complex as
catalyst, Pd(PPh3)2Cl2. The typical reaction has been performed
between glycerol and bromobenzene. This reaction is achieved
in
water as solvent. However, the catalyst complex does not dissolve
in aqueous solutions rather it acts as heterogeneous catalyst.
Therefore, it is filtrated at the end of the reaction and reused several
times. Accordingly, new compound were prepared by reacting
glycerol with 1-bromo-2,6-dichlorobenzene. It is anticipated that the
synthesized compounds may have pharmaceutical application.
