Abstract:

Pseudocedrela kotschyi (Meliaceae) stem bark has been used for the treatment of numerous diseases but without standardisation. The study is aimed at evaluating Pharmacognostic parameters of P. kotschyi stem bark. Standard methods of evaluating crude drugs were used to establish the pharmacognostic parameters. The microscopy study revealed the presence of cambium, pith, epidermis, cortex, vascular bundles, calcium oxalate crystals and long lignified fibres. The chemo-microscopy revealed the presence of some cell inclusions and contents. The averages of physico-chemical parameters values obtained (moisture content 5.22%, total ash 11.23%, acid insoluble ash 3.20%, water soluble ash 7.23%, alcohol extractive 15.83% and water extractive 24.68%) were within permissible limits. The micrometry of the calcium oxalate crystals gave averages of length and width as 35.13µm±4.14, 17.57 µm±2.62 respectively while those of fibres were 824.25 µm ±36.01, 14.05 µm ±1.44, respectively. The elemental analysis established the presence of some macro and micro elements. The powdered stem bark of P. kotschyi under daylight and UV- visible at short (254 nm) and long wave (365 nm) lengths emitted medium range of diagnostic colours. The pharmacognostic parameters of P. kotschyi stem bark that have been established can be used in future studies for ensuring identity, purity and quality.
