Production of anthraquinones by immobilized Frangula alnus Mill. plant cells in a four-phase air-lift bioreactor
(Applied Microbiology and Biotechnology, 1995)
The production of anthraquinones by Frangula alnus Mill. plant cells was used as a model system to evaluate the performance of a liquid-liquid extractive product-recovery process. The shake flask experiments have shown ...
Chaerophyllum coloratum L.: Essential Oils of Ripe Fruits and Umbels
(Taylor & Francis, 1995)
Essential oils of ripe fruits and umbels of Chaerophyllum coloraturn L.(Apiaceae) were found by GC and GC/MS to contain very high percentage of (E)--β-farnesene.
(79.21% and 68.40% respectively).
Spectrophotometric investigation of metopropol-benzyl orange reaction and its application to the assay in pharmaceutical dosage forms
(Farmaco, 1995)
A sensitive spectrophotometric method for the determination of metoprolol tartrate in tablets and ampoules is presented. Using spectrophotometric measurements, it was found that metoprolol tartrate and benzyl orange form ...
Third-order derivative UV spectrophotometry and densitometry for the simultaneous assay of acetylsalicylic acid and salicylic acid in tablet formulations
(Societa Chimica Italiana, 1995)
Third-order derivative spectrophotometry is proposed for simultaneous determination of acetylsalicylic acid and free salicylic acid in sustained-release tablets, and compared with TLC-densitometry. Both methods were evaluated ...
HPLC method for determination of oximes HI-6 and trimedoxime in plasma / HPLC metoda za odredivanje oksima hi-6 i trimedoksima u plazmi
(Jugoslovenska medicinska biohemija, 1995)
A high-performance liquid chromatographic (HPLC) assay was developed to determine HI-6 and trimedoxime concentrations in small volumes of plasma. The HPLC system comprised a high-pressure pump (model 2150), a multiwavelenght ...
Effect of selected direct compression excipients on the stability of acetylsalicylic acid tablets
(Editio Cantor Verlag GmbH, 1995)
The effect of some direct compression excipients (Avicel® PH 101 (I), Avicel PH 101 + mannitol (II), Avicel PH 112 (III), Cellactose® (IV), and Pharmatose® DCL 40 (V)) under different storage conditions (22, 43 and 73% ...
HPTLC assay of acetylsalicylic acid and the impurity salicylic acid in pharmaceuticals
(Akademiai Kiado Rt., 1995)
Spectrophotometric determination of fusidic acid and sodium fusidate in dosage forms
(Journal of Pharmaceutical and Biomedical Analysis, 1995)
Spectrophotometric determination of nizatidine in pharmaceutical formulations
(Journal of Pharmaceutical and Biomedical Analysis, 1995)
Study of protolytic, hydrolytic and solubility equilibria of midazolam
(The Analyst, 1995)
Protolytic equilibria of midazolam in the pH range 0-12 were investigated. Acidity, hydrolysis, equilibrium constants in the heterogeneous system and the solubility of midazolam were determined [I = 0.1 mol l-1 (NaCl), 25 ...
