The phytochemical investigation is effective in discovering bioactive markers of plants for their therapeutic value. Hence several phytochemical surveys have been carried out for detecting diverse groups of naturally occurring phytochemicals. Identifying different classes of phytoconstituents present in various parts plants and extracting the active components could be further taken for investigation and research. Present study describes some quality control parameters like extractive values, preliminary phytochemical studies, ash value, foreign organic matter, foaming index, swelling index, loss on drying and crude fibre of selected plants namely Pterospermum suberifolium,  Givotia moluccana, Ixora parviflora. All methods were carried out using standard methods. For extractive values and preliminary studies various solvents like hexane, chloroform, ethyl acetate, acetone, methanol, ethanol and water were used. Three plants showed more extractive value and significant phytoconstituents like alkaloids, flavoniods, glycosides, saponins, phenols, terpenoids, and tannins in methanolic extract. There was no foreign organic matter in all three plants. The foaming index was less than 100 for P.suberifolium, G.molucanna and greater than 1000 for I.parviflora. The total ash value was obtained as 12.36%, 11.58%, 11.78%, the swelling index was 7.4cm, 6.2cm, 3.6cm, LOD was 11%, 4.68%, 9% and crude fibre content was 26.58%, 14.18%, 41.24% for P.suberifolium, G.molucanna and I.parviflora respectively. The plants resulted in identification of major secondary metabolites by which various pharmacological activities can be established. Other proximate values gave the quality control aspects of plants that are helpful for standardization.
