Effect of far infrared drying temperature on the physical and chemical properties of water extract of A.Malaccensis leaves

A.Malaccensis have been proven by many researcher that there are alkaloids, tannins, saponins, flavonoids, terpenoids and phenolic compound in this species. In order to study the effect of drying temperature on chemical and physical properties of this leaves and to study the amount of active compound, Far Infrared Radiation (FIR) dryer and hydrodistillation method were used. For the drying process, A.Malaccensis leaves were dried at 40°C, 50°C and 60°C using FIR dryer and being extracted using hydrodistillation for 4 hours. From drying process, color of the leaves became darker (more brownish) and the moisture content evaporated percentage were increased proportionally with the increasing temperature (40°C:58.97%, 50°C:69.12%, 60°C:78.37%). From Elemental Analyzer analysis, carbon at temperature 60°C has the highest amount (47.9358) and Gas Chromatography-Mass Spectrometry (GC-MS) analysis shows that 48 active compounds were found in sample A (40°C), 35 compounds in sample B (50°C) and 33 compounds in sample C (60°C). Result from this research show that drying temperature at 40°C have higher amount of compound extracted from the hydrodistillation
