Abstract

The pharmacognostic profile of crude drug has key role in standardization for quality, purity and drug identification. Various pharmacognostic studies of Viola betonicifolia were carried out in order to establish parameters for its identification and to check adulteration or contamination by other species of Viola. Morphological characteristic of the whole plant and its anatomic parts were studied by organoleptic evaluation. Transverse sections of the root and petiole were prepared and studied. Powder drug study of the whole plant was also carried out and various structures of the powder drug were observed. This study also includes the numerical and quantitative leaf microscopy, ash values and extraction values. The pharmacognostic profile of V. betonicifolia was first time studied in this research paper.

Key words: Viola betonicifolia, morphological, organoleptic evaluation.
