The Stability

A high performance liquid chromatography (HPLC) method was developed and validated for determination of flunitrazepam in human plasma. After a simple liquid-liquid extraction, the analyses were carried out on a ODS column with diode array detection at 330nm. The mobile phase consisted in a mixture of potassium dihydrogene phosphate/acetonitrile (40/60, v/v). The method showed good linearity, accuracy and precision. Advantages of this validated assay include a simple plasma extraction method, short analysis time and good sensitivity (LLOQ = 5ng/mL). The stability data indicated a potential instability of flunitrazepam in plasma at room temperature.

Marine Strain

A high-performance liquid chromatography method was developed and validated for the quantification of the cytotoxic compounds produced by a marine strain ofAspergillus niger. The fungus was grown in malt peptone dextrose (MPD), potato dextrose yeast (PDY), and mannitol peptone yeast (MnPY) media during 7, 14, 21, and 28 days, and the natural products were identified by standard compounds. The validation parameters obtained were selectivity, linearity (coefficient of correlation > 0.99), precision (relative standard deviation below 5%), and accuracy (recovery > 96).
