Preliminary Quantification of Phytochemicals in Methanolic Extract of Rosmarinus officinalis L Using HPTLC

Rosmarinus officinalis L. commonly known as Rosemary belong to the family Lamiaceae. It is an aromatic herb which is hardy, dense and evergreen in natural habitat. It is one of the medicinal plants which is cultivated around the world for its medicinal, therapeutic purpose and is used as condiment and food preservative.

It is a perennial herb reaching 100 to 210 cm in height having pointed and hairy, resinous dark green leaves with lower white surface. The present study review about macroscopical/botanical description of Rosmarinus officinalis L. and its methanolic extraction analysis for preliminary quantification of chemical constituents by visualizing TLC plate under different wavelength of UV light i.e., 255nm, 366nm and 566nm to get chromatograph by HPTLC.
