Author(s): P. Selvakumar, Devi Kaniakumari, V. Loganathan
Abstract: The present investigation reveals standardization which includes moisture content, total ash, acid insoluble ash, water soluble extractive value and loss on drying of Alocasia Sanderiana W.Bull ethanolic leaf, stem and root tuber extracts. Total ash value is useful in determining authenticity and purity of drug and also these values are important quantitative standards. Total ash value of plant material indicated the amount of minerals, and earthy materials present in the plant material. Analytical results showed the total ash higher value was 3.30% w/w in ethanolic root tuber extract of alocasia sanderiana. Percent weight loss on drying or moisture content of ethanolic leaf, stem and root tubers extracts is 63.69%, 73.35% and 75.63%. The less value of moisture content could prevent bacterial, fungal or yeast growth. Leaf ethanolic extracts having less value compared stem and root tuber extracts. Ethanolic leaf extracts shows more antimicrobial activity. The higher amount of acid-insoluble siliceous matter present in the tuber extracts of A.Sanderiana was 0.95w/w%. The water-soluble extractive value indicated the presence of sugar, acids, and inorganic compounds. The ethanolic root tuber extract have higher value of water soluble extractive values.
