Diplazium esculentum (Retz.) Sw. (Family: Athyriaceae) is one of the very popular edible ferns, a common pteridophytes usually included in one of the major ingredients in the traditional ‘Ulam’ (salads) preparations in Malaysia. The plant is highly valued for its several medicinal attributes. The present paper reports the physicochemical studies of the aerial parts. Diagnostic characteristics of the aerial parts powder showed presence of lignified xylem fibres and non-lignified phloem fibres, fragments of epidermal cells containing anomocytic stomata, mesophyll, palisade cells, parenchyma and collenchyma tissues, covering trichomes and prismatic crystals of calcium oxalate. Preliminary phytochemical screening of different extracts showed presence of steroids, triterpenoids, tannins and phenolic substances, flavonoids, carbohydrates, gum and mucilage. The findings of the study will provide substantial information for the proper identification of the plant drug to the future investigators.
