Abstract

Problem statement: The main active compounds of benalu teh’s include alkaloids and flavonoids, therefore antioxidant of it has big potential to develop. In the context of extraction, the traditional (boiling in the water until one-third remain) extraction require a long extraction time and result in low yields of extraction also antioxidant activities. Approach: Batch reactor is extraction at high temperature under applied pressure to keep the solvent under liquid phase, by this technology we hope to obtain better results. Optimum extraction conditions of benalu teh need to be discovered to obtain the antioxidant inside it. Benalu teh was extracted using traditional and batch reactor with different solvents (water, 30, 50, 70 and 99% ethanol) at different temperatures (40-180°C) for different time periods (10-20 min) under additional pressure 0.2 MPa. Results: The best extraction condition by batch reactor extraction was 30% ethanol solvent at temperature 100°C for 10 min. Conclusion: Batch reactor extraction gave a better result than traditional extraction on extract yield, radical scavenging activities and total phenolic compound compared with the traditional extraction.
