Objective: To evaluate feasibility of fresh-cut process for Inulae Radix and improve traditional slicing process of it. Method: The contents of alantolactone

isoalantolactone and total flavonoids were employed as indicators

effects of water content

drying styles and slice thickness on fresh-cut process of Inulae Radix were investigated by orthogonal test

then compared with conventional slicing process.The content of total flavonoids was determined by UV;The contents of alantolactone and isoalantolactone were determined by HPLC

chromatographic conditions were as follows:SHIMADZU C18 column(4.6 mm×200 mm

5 μm)

mobile phase of acetonitrile-0.1% phosphoric acid(50:50)

column temperature 30 ℃

flow rate 1.0 mL·min-1

detection wavelength 220 nm

injection volume 20 μL. Result: Optimized fresh-cut process was:water content 35%

drying styles of shade drying

slice thickness 2.5-3.0 mm.The contents of alantolactone

isoalantolactone and total flavonoids from fresh-cut pieces were (22.41±1.38)

(12.87±0.73)

(15.04±0.64) mg·g-1

but in traditional slicing process were (22.94±1.24)

(13.24±0.83)

(14.12±0.58) mg·g-1. Conclusion: Fresh-cut process of Inulae Radix was stable and meaningful.
