Abstract (2. Language):
In this study a spectrofluorimetric method has been developed for assay of mebendazole
(MBZ) drug active compound in tablets. For this purpose; taking measured
fluorescence intensities of mebendazole drug active compound in various solvents, it
was determined that suitable solvent was dimethyl sulfoxide and the wavelengths of
excitation and emission were 390 nm and 473,6 nm, respectively. Calibration graphs
were drawn and the fluorescence intensity was linearly related to the drug
concentration which is between 0-2,5 mg/L (R
2
= 0,9993). Mebendazole in Vermazol
tablet was determined both from calibration graph and from standard addition method.
The validity of the method was tested by the recovery studies of standard addition to
pharmaceuticals and the result was found to be satisfactory. The results obtained from
spektrofluorometric method were compared with official USP 24 method and were in
good agreement and no significant difference between the two methods at 95 %
confidence level was found. The proposed method is simple, accurate and sufficiently
precise for quality control purposes in routine analysis of mebendazole in drugs.

Bu çalışmada, tabletlerde mebendazol (MBZ) ilaç etken maddesinin tayini için
spektroflorimetrik bir yöntem geliştirildi. Bu amaçla, mebendazol ilaç etken maddesinin
çeşitli çözücülerde floresans spektrumlarıalınarak en uygun çözücünün dimetil sülfoksit
ve bu çözücü ortamında uyarma (λuy) ve emisyon (λem) dalga boylarının sırasıyla 390
nm ve 473,6 nm olduğu belirlendi. Kalibrasyon grafikleri çizildi ve bunların 0-2,5 mg/L
derişim aralığında doğrusal olduğu görüldü (R
2
= 0,9993). Doğrudan kalibrasyon
grafiklerinden ve standart katma yöntemiyle Vermazol tabletindeki mebendazol miktarı
tayin edildi. Geliştirilen spektroflorimetrik yöntemle elde edilen sonuçlar, standart USP
24 yöntemi ile elde edilen sonuçlarla karşılaştırıldıve iki yöntem arasında % 95 güven
seviyesinde anlamlıbir fark olmadığıtespit edildi. Önerilen yöntemin, ilaçlarda rutin
mebendazol analizinde kalite kontrol amacıyla kullanılabilecek kolay, doğru ve
kesinliği yüksek bir yöntem olduğu belirlendi.
