Pharmacognostic Characterization and Phytochemical Screening of Launaea procumbens
Mayuri C. Rathod, D. A. Dhale
Launaea procumbens is not employed by the pharmacist but has a good potential in future galenicals. The present communication deals with the pharmacognostic characterization on the different parts of Launaea procumbens (Roxb.) Ramayya and Rajgopal, family-Asteraceae (Compositae). Macroscopic and microscopic examinations of the different organ like stomatal frequency, stomatal index, palisade ratio and macerated vessels, observations and differential microchemical test have been carried out for the authentication of the samples. Physiochemical values such as the Moisture contents, percentage of total ash, acid insoluble ash, acid soluble ash, water soluble ash, extractive values as petroleum ether-soluble extractives, ethanol-soluble extractives, methanol-soluble extractives and water-soluble extractives were calculated as well as colour reactions of powder and extract with different chemicals were performed to observe fluorescence analysis. The extracts were subjected to qualitative screening test for various constituents. This revealed the presence protein, glycosides, alkaloids, tannins and phenolic compound, steroid reducing sugars and saponin glycosides. These observations will help in the Pharmacognostical identification and standardization of the drug in the crude form and also to distinguish the drug from its adulteration.
