Abstract: The present study investigated importance of feather compost as bio-fertilizer to increase the fertility of soil and growth of C. roseus. The screening of primary and secondary metabolites was carried out in the effect of feather compost on the growth of a C. roseus plant. The presence of feather compost has significantly increased primary and secondary metabolites as compared to control one. The crude ethanol extract of C. roseus plant leaves analyzed over TLC, shows prominent orange brown colour band indicating the presence of vincristine to that of standard vincristine sample. The compound was identified with alkaloid extraction of Et-OH in mass spectrum. Comparing the mass spectrum obtained with database the molecular formula C46H57N4O10 and molecular ion peak at 825 was found.
