Extractions of catechu from different layers of the stem of Acacia catechu tree

Bangladesh Journal of Scientific and Industrial Research 26(1-4): 171-174

Extractions of catechu from different layers of the stem of Acacia catechu tree

Catechu (khair (used in the tanning industry)) has normally been extracted from the red heartwood of A. catechu. In order to ascertain the presence and amounts of catechu in other layers of the tree, a portion of the stem of a tree of 55 cm diameter, from the Botanical Gardens of BCSIR Laboratories, Rajshahi, Bangladesh, was subdivided into four layers (outermost bark, inner bark, sapwood and red heartwood) and catechu extracted from each using 2 methods (conventional and Soxhlet).
