<![CDATA[Black Tea (Camellia sinensis L.) is known to have chemicals that are beneficial that are beneficial to health. With the potential of black tea plant as a medicinal plant, it is necessary to do a standardization of the black tea leaves simplicia to determine the quality, safety, and efficacy of simplicia raw materials used in supporting health. This study aims to determine the specific parameters of black tea leaves simplicia. Determination of specific parameters include identification of macroscopic and microscopic powder simplicia, water soluble ash content, ethanol soluble ash content, catechin level in simplicia. Standardization of black tea is based on common standard parameters of medicinal plant extracts. Standardization of simplicia includes organoleptic, soluble compounds in water solvents and ethanol solvents, determination of catechin levels using HPLC. The result of simplicia standardization test shows simplicia has brownish black color, distinctive odor of dried leaves and taste of chelatic taste and slightly bitter, with the water soluble ash content of 22.4935 ± 0.1595%, ethanol soluble ash content of 22.5867 ± 0.1930%, and levels of Catechin 15,6742 ± 1,0513 %. Black tea leaves simplicia (Camellia sinensis L.) meets specific parameters.]]>
