Abstract: The primary objective of the study is to find the potentiality of organic (combination of vermicomposts prepared from cow dung. press mud, tea dust and vegetable wastes in the ratio of (1:1:1:1) and inorganic fertilizer (NPK, 1:2:1 ratio) amendment on the preliminary phytochemical constituents of petals of Rosa bourboniana. The plot with no amendment served as the control. The experiment was arranged in a complete randomized block design (CRBD). An extrapolated value of 6 tons ha -1 of amendments were used during the overall 330 days of cultivation period. At the end of the cultivation period the petal extracts of Rosa bourboniana with various solvents viz., Hexane, chloroform, ethyl acetate and ethanolic fractions were evaluated for preliminary phytochemical analysis. In the present study petals of Rosa bourboniana showed positive results for the presence of carbohydrates, glycosides, cardiac glycosides, flavonoids, alkaloids, tannins, steroids, phenols and aminoacids within hexane, chloroform, ethyl acetate and ethanolic fractions. The preliminary phytochemical screening of petals of Rosa bourboniana showed significantly higher rates for the presence of various phytochemicals. Since phytochemical screening gives the exact profile of the phytochemical quality of plants the results obtained with the higher content of phytochemical constituents in the flowers from the vermicompost amended plot (T1) confirms the positive role of vermicompost in modifying the phytochemical content of Rosa bourboniana comparing to that of the chemical fertilizer. Levels of phytochemicals are found to be lower in the flowers from the chemical fertilizer amended plot (T2) and slightly higher than the control plot (T3).
