Preliminary pharmacognostic standardization of leaves of Camellia sinensis leaf (Theaceae)

Abstract

Camellia sinensis, being belonging Theaceae family, is present more India less than China. A study on Camellia sinensis leaves sample extracted the air-dried leaves powder with different solvents like n-hexane, petroleum ether, chloroform (61̊C), ethanol (78̊C) and distilled water. Preliminary phytochemical analysis was done measurement of various parameters like extractive value, (moisture content) loss on drying, and quantitative estimation of total ash, and acid insoluble ash, and water-soluble ash value may be helpful for identification of tea leaves powdered drug. The fully grown leaves are bright green colour smooth and leathery, young leaves are pubescent. The estimation of powder microscopy presence in the parenchyma, calcium oxalate, vascular traces, upper epidermis and lower epidermis. These studied recommended that the examined pharmacognostic and phytochemical parameters are of whole great value in quality control, formulation development, and biological activities of camellia sinensis.
