Abstract

A survey was conducted on the tapping of Dipterocarpus kerrii for its oleo-resin by the Orang Asli (aborigines) of Tasek Bera and Buloh Nipis. The method of tapping currently employed leads to the destruction of some wood and the production of low yield and poor quality oleoresin. The tapping technique was improved by applying the bark-chipped method with aqueous sulphuric acid solution as a stimulant. The optimum concentration of the aqueous acid used to stimulate maximum oleo-resin flow was determined. This method proved to be advantageous and economical since minimal concentration of aqueous sulfuric acid solution could be used to produce optimum yield and better quality oleo-resin with less damage inflicted on the tree.
