Abstract:
Antibacterial, anticancer, antifungal, antimicrobial, antioxidant and other properties of Simarouba glauca leaves were well interested in the research area. An attempt to dry the leaves of Simarouba with the conventional resources have not been reported well. The experiment was carried out with six different drying methods; shade, sun, tray, solar, biomass and hybrid drying of pharmaceutically important Simarouba glauca leaves. The results showed that product was dried under falling rate period. Temperature affected the drying time, final moisture content and colour value of dried product. Time of solar radiation exposed to the product affected total phenolics and total flavonoids. Tray, Solar, biomass and hybrid drying methods resulted with significantly lower drying time as compared to shade and sun drying. Hybrid mode of drying resulted with 20 h of total drying time including 8 h of solar energy based drying and remaining with the help of biomass energy. Around 60% of moisture was removed by biomass energy drying during hybrid drying. Hybrid drying also retained colour and phytochemicals (Phenolics and flavonoids) as well. Thus, hybrid drying would be the promising method for drying of temperature sensitive materials with conventional energies as a heat source for drying air.
