Preliminary phytochemical screening has been performed in
petroleum ether (40-60°C) benzene, chloroform and ethanol extracts of the taxa
for the presence of steroids, triterpenoids, sugars, alkaloids, phenolic
compounds, flavonoids, catechins, saponins, tannins, anthraquinones and amino
acids. Among the solvents used for extraction ethanol is found
to possess more number of compounds than the other solvents. Among the
compounds tested all the fern taxa poooooo otoroido, ougars, alkaloids, plwnols,
fhrvonoicL , RaponinR, tannim: and amino acids. Triterpenoids, catachins and
anthraquinones are completely absent in
all the fifteen taxa.
