2006
Palmina, K. | Mahdi, H. | Glavtch, I.
Tannins from four indigenous and exotic woody plant species were studied by different methods with objectives of evaluating the quantity and quality of extractable tannins for comparisonwith standard Acacia mearnsii (wattle) tannins. The results showed that of the seven materials studied sixhad > 10% tannin content and were thus suitable for commercial exploitation. Thin layer chromatography indicated and confirmed the differences of the chemical nature of the materials as mixed and condensed tannins. The protein precipitation behaviours confirmed complexity and differences in their nature and potentiality for tanning or other uses compared with A. mearnsii. The tannin type of A. nilotica species was of hydrolysable-condensed while that of A. mearnsii was of condensed type.
