ABSTRACT

Pteridophytes are recognized for their biological and medicinal properties for long time but very less work has been done on wetland pteridophytes. In our present study we evaluated the antioxidant activity of two wetland pteriodphytes Diplazium esculentum (Retz.) Sw. and Marsilea minuta L. Presence of bioactive compounds like phenols, flavonoids and saponins was detected in both the plants. However, alkaloids, triterpenes and anthraquinones were exclusively detected in Diplazium esculentum. Methanolic extract of both the plants showed potential antioxidant activities. The IC50 values of Diplazium esculentum for DPPH, ABTS, metal chelating and superoxide ion scavenging activity were found to be 3.8, 4.6, 1.09 and 2.24 mg/ml. Dose dependent inhibition of free radicals was also observed in case of M. minuta. The IC50 values of M. minuta for DPPH, ABTS, metal chelating and superoxide ion scavenging activity were recorded to be 7.7, 6.4, 0.59 and 4.69 mg/ml respectively. The presence of compounds like total phenols, flavonoids, protein, total sugar, reducing sugar, free amino acid and chlorophyll content were also evaluated in these two plants. However, total phenol and flavonoids content was recorded higher in case of D. esculentum.
