The sample with Rf
value 0.79 was taken up for further study. This sample was
positive in Liebermann’s Burchard test3
and gave purple
colour indicating terpenoid nature of the compound and
had melting point of 780C. This terpenoid sample positive
towards to 2, 4-Dinitrophenylhydrazine test, indicating
presence of aldehyde/ keto group.
4 The sample was then
further analysed through various spectroscopic techniques
like UV spectroscopy (UV- 1601PC, UV-Visible
Spectrophotometer, Shimadzu), FT-IR spectroscopy
(Perkin Elmer Spectrum- 1 Spectrophotometer), High
Resolution Mass spectroscopy (JEOL- JMS 600
Instrument) and Nuclear Magnetic Resonance
spectroscopy, 1H & 13C (Bruker Avance- 400
Spectrometer) for its proper physicochemical
characterization
