Background : Anemarrhena asphodeloides Bunge is herbaceous perennial plant used for medicine with tuber root. This experiment was conducted to establish proper drying method of Anemarrhena asphodeloides for GAP post-harvest management manual. Methods and Results : Anemarrhena asphodeloides radix was cut in 3mm thickness after washing. Drying methods were air curing, sun drying, and hot-air drying (45℃, 50℃, 55℃, 60℃). Dry matter ratio (DMR) and moisture content (MC) were checked for every 12 hours for air curing and sun drying and checked for every 2 hours for hot-air drying. In 6 hours hot air drying at 45℃ and 50℃, DMR and MC were 39.9%, 38.4% and 13.5%, 12.8% respectively. In 4 hours hot air drying at 60℃, DMR and MC were 38.0% and 13.6% respectively. In air curing and sun drying for 4 days, DMR and MC were 37.0%, 37.6% and 12.3%, 13.1% respectively. Color value according to drying methods was higher as 74.57 in ℓ value under 50℃ hot air drying and lower as 65.35 under air-curing. a value was higher as 3.50 under air-curing and lower as 0.47 under 50℃ hot air drying. Conclusion : In 6 hours hot air drying at 50℃, MC was 12.8% and color value was higher as 74.57 in ℓ value and lower as 0.47and 22.59 in a value and b value respectively. This result showed that hot air drying for 6 hours at 50℃ was more proper for Anemarrhena asphodeloides radix drying.
