The total acetone extract from the timber of Acacia mollissima Willd (black wattle) contains phlobatannin, ‘phlobaphene,’ pinitol, fructose and an iso hexane‐soluble fraction consisting mainly of a monohydric alcohol which shows sterol reactions. The tannin and phlobaphene differ from wattle‐bark tannin and from one another in their degree of hydroxylation, but yield oxidation products of similar type and methylated derivatives of high molecular weight (1300 to 4800). Chromatographic separation of the products of alkali fusion reveals a number of benzenoid hydroxy‐acids. A preliminary survey shows that there are wide variations in the yield of extractives from different trees grown in a single plantation.
