Albizia Myriophylla, or Tebu Gajah generally a plant or herb as an alternative to antidiabetic medicine widely used in ancient times because of its benefits and functions in treating diseases such as reducing glucose in the blood. However, the scientific substance that responds was unknown. To overcome this problem research was carried out using GCMS testing to identify the respective bioactive compounds that were actually responsible for anti-diabetic properties. This research aims to investigate the effect of different process parameters on the yield of extracted phenolic compounds of Tebu Gajah using the method of Soxhlet. For this purpose, the experiment was run using different parameters and the best for extraction of Tebu Gajah was methanol as solvent, at 5 hours,. The best parameter for enhancing the yield of the phenolic compound was the extraction solvent.
