Abstract

Aim: Standardization of Ocimum basilicum through pharmacognosy. Place and Duration of Study: Department of Plant Biology and Plant Biotechnology, Ethiraj College for Women, Chennai “Between” Dec 2014-April 15. Methodology: Organoleptic evaluation was carried out based on sensory characters. A free hand anatomical section of the stem was observed. Powder analysis, maceration, Phytochemical test and Fluorescence analysis were conducted according to standard protocol. Results: The organoleptic characters of the dried leaves of Ocimum basilicum were green, aromatic, pungent and brittle in texture with  anomocytic stomata with stomatal index 71.87% in the lower epidermis. A prominent bundle sheath in the leaf was evident. The macerated stem showed annular xylem vessels. The aqueous extract showed the presence of alkaloids, phenols, flavonoids, steroids, terpenoids, and glycosides. Alkaloids and lignins were evident in the histochemical study. Conclusion: Pharmacognostic evaluation of Ocimum basilicum would help in identification, detection of adulterants and development of a monograph.
