ABSTRACT:
Zingiber officinale has many possibilities as crude drug and also through pharmaceutically extracted medicine. This rhizome belongs to the family Zingiberaceae. Phytochemical constituents of plants are the key ingredients of many pharmaceuticals. The main variation of phytochemicals from crude drugs is their extraction by employing industrially applicable sophisticated techniques for manufacturing various medicaments. Nowadays many crude drugs have been used for synthesizing plants based medicines around the world. The present study aimed at qualitative as well as quantitative estimations of Zingiber officinale by physical tests, chemical estimations, Thin layer chromatography and UV- Visible spectroscopy. The pharmaceutical active ingredient of Zingiber officinale is gingerol whose (Retention factor) Rf value found to be 0.85. The quantitative estiation of gingerol is carried out with the help of double beam UV-VIS Spectrophotometer:5204 at absorption maxima of 282.8 nm. The percentage concentration of gingerol in its Zingiber officinale extract found to be 67.84%.
