Pharmacognostic specifications of Abroma augusta stems and Cissus quadrangularis aerial part

Abstract

In present communication pharmacognostic specification of medicinal plants used in veterinary products have been described for the purpose of their standardization. The plants undertaken for the study were Abroma augusta stem (Sterculiaceae) and Cissus quadrangularis (Vitaceae). These plants are official in Ayurvedic Pharmacopoeia of India. The observed microscopic characters of Abroma augusta stems are suberized cork cells, pericyclic fibers, polygonal parenchymatous cells. Microscopic characteristics of Cissus quadrangularis aerial part shows chlorenchymas hypodermis, sclerenchyma sheath; large cells of mucilage along with clusters and bundles of acicular crystals of calcium oxalate were seen in abundant and were scattered throughout the section. Powder microscopy of both the plants was also studied and identifying features were noted down. The improved qualitative microscopic features would prove useful for their quick identification and laying down their pharmacopoeia standards. Additionally, present study also provides the information with respect to crude drug and may serve as a reference point for the proper identification of Abroma augusta stems and aerial parts of Cissus quadrangularis. The present study would also fill the gap in providing evidential support concerning quality determination of plant material used in veterinary medicinal product. Emphasis is upon aiming to increase documentation on primary studies on medicinal plants used in veterinary medicines.
