Pharmacognostical Study and Quality Control Parameters of Dillenia indica Linn. and Dillenia pentagyna Roxb.: A Boon of Ethnomedicinal Herbs of India

Abstract

Dillenia indica Linn. and Dillenia pentagyna Roxb. are two plants which are found to be widely growing plants in many forest regions of India. The quality parameters are set for assuring the standards of plant species. Pharmacognostical and physicochemical parameters are developed which ensures the quality of drug as well as differentiate both plant species. Bark of both plants differentiated morphologically by its colour as well as texture while leaves of both plants differentiated by its size, shape. Microscopically, bark can be differentiated by presence of stone cells, cork, pigments and raphides of Ca-oxalate and leaves based on its trichomes, raphides etc. Physicochemical parameters (extractive values, ash values, foreign matter, moisture content) were determined to ensure quality of plants. Phytochemical screening is performed to have an idea about active phytoconstituents present in plants. Results of heavy metal and microorganism revealed that plants are safe to use further for separation of phytoconstituents. Phytochemical screening of different extracts of bark and leaves revealed the presence of sterols, flavonoids, phenolics etc.
