FT-Raman phytochemical analysis of Hypericum perforatum L. (Hypericaceae) species

Abstract

Hypericum perforatum L.(St. John’s wort) is a perennial herbaceous
plant displayed an important role in pharmaceutical and medicine
applications. Fourier transform raman spectroscopy (FT-Raman)
technique has been employed to determine the chemical constituents of
four wild H. perforatum(HP)genotypes collected from rural regions of
Lattakia-Syria. FT-Raman analysis highlighted 7, 5, 6 and 6
distinguished peaks for HP1, HP2, HP3 and HP4 genotypes,
respectively. Of which three peaks were common for the four studied H.
perforatum genotypes: peak of 1250cm-1
assigned to C–O stretchCarboxylic acids group, peak of 1600cm-1
assigned to C=C stretch
aromatic-Aromatics group and peak of 2850 cm-1
assigned to C–H
stretch-Alkanes group. These functional groups known to exhibited
different biological activities worldwide. This report could be considerd
as the first study of H. perforatum FT-Raman.
