가을울금과 봄울금의 채취시기에 따른 일반성분, 아미노산, 유리당 및 환원당 및 비타민 C와 등의 함량을 비교분석 하였다. 가을울금과 봄울금의 수분, 조회분, 조단백 및 조지방 함량은 채취시기가 늦을수록 증가하였고, 가용성무질소분 함량은 채취시기가 늦을수록 감소하는 경향을 보였다. 구성아미노산은 채취시기가 늦을수록 아미노산의 함량이 증가하다가 다음해인 1월말에는 약간 감소하였으며, 총 아미노산에 대한 필수아미노산의 비율도 증가하였다. 유리 아미노

Changes in proximate composition, amino acid, free sugar, reducing sugar and vitamin contents of Curcuma longa L. (autumn woolgeom in Korean) and Curcuma atomatica Salib (spring woolgeom) were investigated according to picking time. Moisture, crude ash, crude protein and crude lipid were increased and non nitrogen substances was decreased by extending the picking time. Contents and ratio of total amino acid to essential amino acids was increased by extending the picking time. Free amino acid was increased by extending the picking time. Ratio of essential amino acids to total amino acids was decreased. Fructose was gradually increased, and then glucose, sucrose and total free sugars were decreased by extending the picking time. Amino acid and sugar contents of Curcuma longa. L. were higher than those of Curcuma atomatica Salib. In contents of vitamin C and , Curcuma longa L. was decreased and Curcuma atomatica Salib was increased by extending the picking time.
