Zaka Khan, Shivani Kakkar, Saurabhi Ghag, Shruti Shah, Sonali Patil and Annika Durve Gupta*

ABSTRACT

Caffeine is used in wide range of pharmaceutical formulations and
beverages (Cola Drinks), Ayurvedic medicines and in some confectionery.
In the present work, a simple, fast and low cost procedure for
extraction of caffeine from waste tea leaves, from various sources, was
carried out. TLC analysis was carried out for the detection of caffeine.
HPLC and FTIR analysis were performed for quantification and characterization
of the extracted caffeine. Antibacterial activity of caffeine
was checked against Gram Negative Bacteria. An attempt has been
made to create a transdermal patch using easily available material. Further
parameters have to be modified to make an effective caffeine de
livering patch. This study showed that tea waste could be utilized for production of valuable
products using nontoxic solvents and substances at extremely short extraction periods.

Keywords: Caffeine, TLC, HPLC, Antibacterial activity, FTIR, Transdermal patch.
