The individual and simultaneous enzymatic determination of ethanol and acetaldehyde in wine by flow injection analysis is described. Individual determinations of 0.002-0.016% (v/v) ethanol or 1.0-8.0 rg ml-' acetaldehyde with r.s.d. 0.7% and 0.5%, respectively, are done with a single-beam spectropho
Based on the electrocatalytic oxidation of cysteine at pretreated platinum electrode and the flow-injection biamperometry for irreversible couple, a novel electrochemical detector is proposed for the selective determination of cysteine in amino acid mixtures and human urine samples.

A sensitive and rapid determination of berberine was carried out by flow-injection analysis. Berberine was successfully extracted in the presence of sodium perchlorate. The calibration graph was linear over the range 4 X 10d9-1 X 1O-6 mol dm-". The sample throughput was 42 h-l.
## Multistep enzymatic reactions take place when sulfated bile acids (SBAs) pass through an immobilized enzyme reactor. First, SBAs take place in the reaction of desulfation under catalytical action of a bile salt sulfatase immobilized in the reactor and formed 3b-hydroxyl bile acids. Formed 3b-hydr
