Abstract:
Objective To establish the analytical methods for determining the contents of tannins in different vegetative organs of Abutilon indicum (L.) Sweet. Methods The content of tannins, expressed as gallic acid equivalents, was measured by using the phospho molybdenum tungstic acid-casein colorimetry. Results The good linearity between concentrations and absorbances of gallic acid was found in the range of 2～10 mg/L, the average recovery was 99.63% and RSD was 1.08%, the contents of tannins in leaves, stems and roots of Abutilon indicum (L.) Sweet were 0.34%, 0.16% and 0.27% respectively. Conclusion The proposed method is sensitive, precise, accurate and reproducible, and it is suitable for the determination of tannins in Abutilon indicum (L.) Sweet.
