Abstract
Standardization of herbal drugs raw material is essential to assess the quality, based on
the consistency (concentration) of their active principles. Tea plant (Camellia sinensis) contains
Caffeine that is responsible for the stimulating effect of the beverage. The objectives of this study
are extraction, qualitative estimation of caffeine by TLC method, physicochemical standardization,
phytochemical evaluation(qualitative tests) and chemical tests for detection of inorganic elements
from different black tea brands. The different black tea brands (Brooke Bond Taj Mahal, Tata
Premium and Duncan Double Diamond) are suddenly collected from local market. Standardization
including – organoleptic properties, foreign matter, pH of aqueous solution ash values, extractive
values, successive extractive values, moisture content, volatile oil content, Preliminary
phytochemical screening and chemical tests for inorganic elements. The results obtained from this
study can be used to standardize different black tea brands in the market.
