Extraction from Different Natural Sources and their Pharmacognostical Studies

Abstract

Natural products from medicinal plants, either as pure compounds or as standardized extracts, provide unlimited opportunities for new drug leads because of the unmatched availability of chemical diversity. The focus of this paper is on the analytical methodologies, which include the extraction, isolation and characterization of active ingredients in botanicals and herbal preparations. The analysis of Phytoconstituents was performed physicochemical parameters (foreign matter, moisture content, loss on drying, total ash, water-soluble ash, acid-insoluble ash, sulphated-ash, alcohol-soluble extractive, water-soluble extractive and pH values), Preliminary Phytochemical Screening (Test for carbohydrates, Test for amino acids, Test for steroid, Test for fat, Test for oils, Test for alkaloids, Test for tannins, Test for phenolic compounds, Test for Saponin glycosides, Test for flavonoids, Test for volatile oils and Test for heavy metals ), Tests for Aflatoxin and Thin-Layer chromatography. The results were discussed that all Phytoconstituents extracted from Fennel, Amla and Tulsi were nom-toxic and safe. All Phytoconstituents were free from heavy metals and Aflatoxin. The major goals of extraction are to increase yields of bioactive substances, reduce extraction time, be more environmentally friendly, and attain economic viability without sacrificing biological activity.
