Coffee, tea, and soft drinks are very commonly used
beverages all over the world. Caffeine stimulates the central nervous system
and promotes relaxation, myocardial stimulation, and recreational activities.
It can provide energy, decrease fatigue, and enhance performance. Caffeine has
medicinal properties so it can be used along with other drugs for headaches,
stimulation, and muscle relaxants. Caffeine is useful with certain limits but
an overdose of caffeine starts side effects on the human body. Various
instrumental methods can be used to analyze caffeine in plants, coffee, tea,
soft drinks, and pharmaceutical formulations in the presence of other drugs.
Different techniques are available to determine caffeine like UV
spectrophotometry, HPTLC-UV, capillary electrophoresis-UV, flow injection
analysis, electrospray ionization (ESI), Gas chromatography, NIRS and Mass
spectrometry in various samples along with pharmaceutical preparations. HPLC
methods are the most common, reliable methods used for the analysis of caffeine
used in industries. HPLC can accurately and precisely detect caffeine in
extremely low concentrations and highly complex materials. This review
summarizes various HPLC methods used for caffeine analysis in samples and
complex mixtures. Various chromatographic conditions are summarized in tabular
form such as different columns, mobile phases, detectors, flow rates, and a
variety of samples. Recent advances in technologies with the use of green
chemicals for sustainable methods for caffeine analysis in different complex
matrix materials have been studied.
