PHYTOCHEMICAL ANALYSIS AND ANTIBACTERIAL ACTIVITY OF CRUDE EXTRACTS AND EXTRACTED PHENOLS FROM A LITHO-EPIPHYTIC FERN ARTHROMERIS WALLICHIANA (SPRENG.) CHING

Antibacterial activity of crude extracts and extracted phenols from sporophytic parts of litho-epiphytic fern Arthromeris wallichiana (Spreng.) Ching (family Polypodiaceae) were studied in summer and winter seasons against Bacillus subtilis AR-2 (Gr +ve) and Escherichia coli XL1-Blue (Gr-ve). Both the crude extracts and extracted phenols from sporophytic plant parts showed antibacterial activities. In summer the phenol content is less and in winter the phenol content is maximum. Detailed observations reveal that crude extracts show better antibacterial activity than extracted phenol.

PHYTOCHEMICAL CONTENTS AND ANTIMICROBIAL EFFECTS OF ETHNOMEDICINAL PLANT ADIANTUM INCISUM FORSK.

The aim of the present study was to find out the antimicrobial activity of crude and phenol extracts obtained from different parts of the sporophytic plant of some selected ethno-medicinal ferns of Arunachal Pradesh, India. Out of which thefern Adiantum incisum Forsk. showed antibacterial activity against both Gram+(Bacillus subtills AR-2) and gram (Escherichia coli XL-1 Blue) bacterial strains. The antimicrobial activity was measured using 'agar cup' method. The extracts from roots revealed better result. Both crude extract and phenol extract showed antibacterial activity. However, the crude extracts were found more effective than phenol extracts.

ANTIFUNGAL RESPONSE OF PHENOLS AND CRUDE EXTRACTS ISOLATED FROM SOME THELYPTEROID FERNS

Crude extracts and extracted phenols from different plant parts (leaf, rhizome, petiole etc.) of some pteridophytes were tried experimentally to test their antifungal properties on a comparative basis. In this study, the antifungal properties of three members of the family Thelypteridaceae viz. Ampelopteris prolifera, Christella dentata, Pronephrium nudatum were tested against a pathogenic fungus Aspergillus niger. The amount of total free phenols from different parts of the above mentioned plants were measured. Presence of maximum amount of free phenols was noted in the sterile leaves and minimum in the rhizomes of all these thelypteroid members studied. Pronephrium nudatumshowed accumulation of highest amount of free phenols in its sterile leaves and lowest accumulation was noted in the rhizomes of Ampelopteris prolifera. Ethanolic crude extracts and extracted phenols from all these plant parts showed antifungal effects.
