Pharmacognostic Standardization of Cedrus deodara stem Bark.

Cedrus deodara (Roxb), Pinaceae, is a species of cedar native to the western Himalayas in eastern Afghanistan. Northern Pakistan (Kashmir), north central India (Himachal Pradesh and Uttarakhand) .It is a large evergreen conifer tree reaching 40-50 tall. The stem bark of the plant is astringent and febrifuge. Scientific parameters are not yet available to identify the exact plant material (stem bark) and to ascertain its quality and purity. The present study deals with the pharmacognostical like macroscopical, microscopical, physical parameters like loss on drying, ash values, extractive values, the stem bark of the plant were subjected to the successive extraction in the increasing polarity order of the solvents, the extracts were used to various phytochemical tests, the stem bark of the plant Cedrus deodara shows the presence of Flavonoids, tannins, Proteins and amino acids in the different extracts, These studies provided referential information for correct identification and standardization of this plant material.
