창포의 뿌리를 주근(main root)과 측근(lateral root)으로 분리하여 3$0^{circ}C$ 열풍건조분말의 주된 포화지방산으로는 caprylic acid, pentadecanoic acid, stearic acid 및 heneicosanoic acid 등 10종이 확인되었고, 이들은 각각 주근과 측근의 경우 caprylic acid가 28.35%, 31.44%이었고, 불포화지방산으로는 linoleic acid, palmitoleic acid 및 linolenic acid 등 6종이 확인되었고 이들 중 가장 높은 함유량을 보인 linoleic acid가 주근에 25.55%, 측근에 23.43%가 함유되어 있었다. 주요 유기산으로는 주근과 측근에 succinic acid, malic acid 및 citric acid 등으로 구성되어 있었고, 특히 succinic acid가 주근과 측근에서 각각 2,790 mg%, 2,630 mg%로 높은 함량을 함유하고 있었다. 무기질로는 K, Ca, p, Mg, Na, Fe, Zn, Mn, Cu 등 9종을 함유하고 있었으며, 창포뿌리의 주된 무기질로 확인된 K의 함량은 측근에 454 mg%로 주근의 194 mg% 보다 매우 높은 함량을 나타내었다. Ascorbic acid 함량은 주근과 측근에 각각 113.8 $mu extrm{g}$/g, 125.1 $mu extrm{g}$/g을 함유하고 있었고, 총페놀성 물질 함량은 주근에 463 mg%, 측근에 474 mg%로 매우 높은 수준이었으며 조사포닌의 함량은 주근에 2.51%, 측근에 3.39%로 높은 함량을 보였다.
This study has been carried out to investigate the composition of fatty Acids, organic acids, minerals, vitamin C, total phenolics and saponin in 30$^{C}$ hot air dried powder of main and lateral root of Acorus calamus L. Major saturated fatty acids were identified caprylic acid, pentadecanoic acid, stearic acid and heneicosanoic acid, etc.. Content of caprylic acid in main and lateral root were 28.35% and 31.44%. Unsaturated fatty acids such as linoleic acid, palmitoeic acid and linoleic acid was highly contented, linoleic acid was highest contented 25.55% in main root and 23.43% in lateral root. Succinic acid was the most abundant organic acid of root content of main and lateral root were 2,790 mg% and 2,630 mg%. Potassium was found to be the mon predominant mineral in root, followed by calcium, phosphorus and magnesium, in a order. Contents of potassium in main and lateral root account for 194 mg% and 454 mg%, respectively. Contents of these minerals in lateral root were higher value than that in main root. Contents of ascorbic acid and total phenolics were 113.8 $mu extrm{g}$/g and 463 mg％ in main root, 125.1 $mu extrm{g}$/g and 474 mg% in lateral root, respectively. Crude saponin content of main and lateral mot were high level amount, 2.51 ％ and 3.39 %.
