ABSTRACT:
In present study, various standardization parameters like macroscopical, microscopical characters, physiochemical parameters like total ash (14.3%), water soluble ash (5.1%), acid insoluble ash (3.7%), sulphated ash (2.3%), foreign organic matter, loss on drying, swelling index (5.1%), both successive and cold maceration in various solvents like petroleum ether (3.5%), benzene (4.2%), chloroform (6.0%), ethyl acetate (6.5%), methanol (13%). Cold maceration values, petroleum ether (3.0%), benzene (3.5%), chloroform (5.0%), ethyl acetate (5.6%), methanol (11.8%). Behaviour on treatment with different chemical reagents of the dried flower heads, fluorescence characters under both visible and ultralviolet light was compared with nerolac synthetic and satin enamel colour reference card. Further preliminary phytochemical screening of different extracts of flower heads revealed the presence of alkaloids, glycosides, carbohydrates, steroids, flavonoids, phenols, proteins and amino acids.
