【 摘 要 】

Sengon is a fast growing plant and recently paid many attentions for timber industry sector. New plantations are established in many province of Indonesia. Including in East Java. Plantation is managed by private, public company, and even by individual farmer. The timber logs are produced to support some industries such as pulp, plywood and constructions. However, the processing still remains a huge waste of wood bark and wood scraps. Some companies disposed the waste into environment and some burnt for firewood. And thus, come up to the environmental issue. This paper reports recent chemicals investigation contained in the Sengon bark and also evaluate the potency to lower of the glucose-related diseases. It is found that bark's crude extract is composed of some group of chemicals, such as alkaloid, flavonoid and triterpenoid. Further separation of the extract into simpler chemicals found the triterpenoid group dominated the composition. UV-VIS and FTIR spectra also confirmed the substituent of the chemicals structures, such as alkyl, hydroxyl, carbonyl, and carboxyl-groups construct the triterpenoid structures. In addition, all these triterpenoids groups can decrease a glucose level in vivo, and the value is comparable to that reference reported.
