Pharmacognostical Standardization of Bark of Thuja Orientalis Linn

The document detailed a pharmacognostical standardization study of Thuja orientalis bark, involving botanical and phytochemical analyses. It described the bark's macroscopic features such as color, taste, and shape, and microscopic cellular structure. Physicochemical evaluations were conducted to determine ash and extractive values for assessing purity and quality. Preliminary phytochemical screening identified glycosides, flavonoids, sterols, tannins, and carotenoids in the extracts. The study concluded that the standardization provided important information for the identification and quality control of Thuja orientalis, which is known for its anti-epileptic, anti-inflammatory, and hair growth-promoting properties. The number of samples analyzed was not mentioned.
