Background : The major compounds of Angelica species are decursin, decursinol angelate, nodakenin, umbelliferone and β-sitosterol, which act anti-inflammatories, reduce pains, protect the liver and enhance the immune system. This study investigated the chemical compositions, minerals, metals, sugars and overall amino acid composition in Angelica gigas Nakai.
Methods and Results : Powder of Angelica roots smaller than 30 mesh were used. Physico chemical analysis revealed the presence of carbohydrates (62.0%), crude proteins (13.9%), moisture (11.4%), crude fats (7.3%) and ash (5.4%). Results showed that potassium was present in the highest amount (1,859 ppm), followed by magnesium (214.5 ppm), calcium (147.3 ppm) and sodium (6.0 ppm). Free sugar profiles showed the presence of sucrose (29.3 g/100 g). The total amino acids concentrations was 9,752 ㎎/ 100 g, the most common and dominant amino acids were arginine (2,181 ㎎/100 g), glutamic acid (1,212 ㎎/100 g) and aspartic acid (834 ㎎/100 g). The total free amino acids contents was 1,476 ㎎/100 g, in which the most common amino acid were arginine (932 ㎎/100 g), glutamic acid (127 ㎎/100 g), and γ-aminobutyric acid (80.4 ㎎/100 g). The fatty acid composition of A. gigas showed a higher concentration of unsaturated fatty acids such as linoleic acid (443.9 ㎎/100 g) and palmitic acid (181.3 ㎎/100 g) according to gas chromatography.
Conclusions : These results showed that Angelica roots can be used in various fields of foods and medicines, and in the preparation of cosmetics.
