Pharmacognostic evaluation of oxalis pes-caprae l. (family oxalidaceae)

Abstract

The present study was conducted on Oxalis pes-caprae L. (Family Oxalidaceae) to analyze its morphological and pharmacognostic features. The results revealed that it leaves are compound, perennial and summer deciduous with upper epidermis followed by mesophyll region with vascular bundle and the lower epidermis. The leaf features showed that palisade ratio was (7.35), vein islets number (9), and vein termination number (9.1), stomata number (47) and stomatal index were (42.72). Transverse section of the root showed outer epidermal cells, cortex and pericycle, xylem and phloem cells. Powder drug microscopy, ash analysis, extractive values and fluorescence analysis were also studied. Preliminary phytochemical screenings of different extracts of Oxalis pes-caprae L. showed the presence of carbohydrates, phenols, flavonoids, tannins, saponin, fats and oils.
