Abstract
Pteridophytes are gaining importance as therapeutic agents due to the presence of various phytochemicals and their promising bioactivities. Drynaria quercifolia (L.) J. Sm., a Polypodiaceae member is endowed with numerous medicinal properties and finds wide usage in ethno as well as traditional medicines. The rhizome of D. quercifolia (L.) J. Sm. was subjected to macro-microscopic, physicochemical, phytochemical and HPTLC analysis to derive a standard for this drug. The microscopic detailing showed a wavy outline due to the presence of ridges and furrows and a broad ground tissue with diffusely arranged steles. The powdered drug showed trichomes, stellar tissue and silica crystals while the physicochemical and phytochemical screenings gave substantial values of different parameters. The rhizome extracts were subjected to HPTLC studies with Linomat 5 TLC applicator and diagnostic peaks were recorded under UV 254 nm, 366 nm and 620 nm. The study put forward an exclusive identity profile of this medicinal rhizome.
Highlights
Drynaria, an ephiphytic fern genus belong to the family Polipodiaceae is represented by fifteen species in the world
Collection and Identification of samples The fresh rhizomes were collected from Yercaud in Salem district, Tamil Nadu during September 2019
Due to the variation in the sources of crude drugs, their morphological, biological and chemical nature, different standardization techniques needs to be incorporated for their identification
Summary
An ephiphytic fern genus belong to the family Polipodiaceae is represented by fifteen species in the world. Podophyllum quercifolium) called as ‘oak leaf ferns’ or a ‘basket fern’ is distributed in Australia, China, India, Indonesia, Malaysia, Philippines, Thailand, Singapore and Srilanka in different habitats like rock crevices, along the soil boulders and very often on the tree trunks [1]. In India this fern is distributed throughout various habitats [2]. It is used in traditional medicinal systems like Ayurveda and folk medicines.
