The plant Acacia catechu (L.f) Willd hydroethanolic leaf extract was subjected to qualitative and quantitative phytochemical screening, HPTLC and GCMS analysis. The phytochemical analysis revealed the presence of carbohydrates, proteins, flavonoids, total phenolics, glycosides, total free amino acids, tannins, alkaloids and thiols. The secondary metabolites like flavonoids, tannins and total phenolics were quantified as 82μg/ml, 67.5μg/ml and 42.5μg/ml.

The antifungal activity of Gracilaria cervicornis, Gracilaria gracilis, Endocladia muricata is tested against Macrophomina phaseolina and Lasiodiplodia theobromae. The mean inhibion zones induced by seaweed extracts on the tested pathogens revealed that methanolic extract of G. cervicornis had highest zone than its acetone & aquous extracts followed by methanoilc extract of G. gracilis against M. phaseolina whereas no inhibition by E. muricata. The methanolic extract of G. cervicornis recorded inhibition zone of 20.7 mm against M. phaseolina whereas in L. theobromae it was 17.6 mm.

Plant has an innate ability to produce non-enzymatic antioxidants which have an important role in the metabolism of Reactive oxygen species (ROS). Several plants serve as the source of therapeutic agents but the properties depend on the plant nature. Thus, an evaluation of antioxidant activity is essential to determine the importance of a plant. Three plants Utleria salicifolia, Plectranthus vettiveroides and Nothapodytes nimmoniana were selected to carry out the antioxidant study.
