Taking inspiration from the method by Suresh et. al , with minor adjustments, the following procedure was developed. 10 grams of the tea was obtained from opening the "Lipton® black tea decaffeinated" tea bags. The tea was added to a 250 ml beaker, and about 200 ml of distilled water was added to the beaker. The mixture was stirred for 30 minutes at 85°C. The extract was filtered through Whatman Grade 1 filter paper into conical flasks and stored at approximately 5°C for further use.
