Pharmacognostic evaluation of Toona Ciliata bark

Pharmacognostic standardizations of powdered and anatomical sections of the Toona
ciliata bark was carried out to determine its macro- and microscopical characters and
also some of its quantitative standards. Externally bark are Grey to reddish-brown in
colour when it is dry, 200 mm in length, 20 to 60 mm in width and 2 to 3 mm in
thickness outer surface brown coloured, strong odour, bitter taste, rough and hard,
double quill and curved curvature. The transverse section (T.S.) revealed the presences
of periderm, cortex, Sclerides, medullary rays and phloem fiber. Physico-chemical
evaluation includes ash values, extractive values and moisture content. These findings
will be useful towards establishing pharmacognostic standards on identification, purity,
quality and classification of the plant, which is gaining relevance in plant drug
research.
