Abstract

Amaranthus spinosus Linn. (Amaranthaceae) is found throughout India. This tree species has been of interest to researchers because it is a medicinal plant employed in the Indian traditional system of medicine. Pharmacognostic standardization; physico-and phytochemical evaluation of the roots of Amaranthus spinosus was carried out, to determine its macro-and microscopical characters, and also some of its quantitative standards. Microscopical studies were done by using the trinocular microscope. Total ash, water-soluble ash, acid-insoluble ash, sulfated ash values, and alcohol-and water-soluble extractive values were determined for physico-chemical evaluations. A preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, the root showed cork, cortex, stellar region, and calcium oxalate crystals. Powder microscopy showed anamalous secondary growth in between the xylem vessels and Calcium Oxalate crystals in the cortex region. Total ash was approximately three times more than acid insoluble and water soluble ash. The ethanol soluble extractive was approximately the same as the water soluble extractive. Thin Layer Chromatography (TLC) of the Petroleum-ether extract using Benzene : Ethyl acetate (6 : 1), showed six spots. In the chloroform extract, using Benzene : Ethyl acetate (4 : 1) nine spots were seen, and in the ethanol extract, using Chloroform: Methanol (93 : 7), only four spots were observed, using Iodine vapor as a viewing medium. Phytochemically, the root exhibited terpenes, alkaloids, glycosides, and sugars. These findings might be useful to supplement information with regard to its identification parameters, which are assumed significant in the way of acceptability of herbal drugs, in the present scenario, which lacks regulatory laws to control the quality of herbal drugs.
