Abstract
|

|
|
As a beauty functional cosmetic material, the composition and content of free amino acids and non-protein amino acid derivatives in hot water and 80% EtOH extracts of red cabbage leaf were analyzed. A total of 14 free amino acids from the hot water extract were isolated, and the total was 38.37 mg/g, of which proline was the most at 24.6 mg/g. In addition, 6 types of essential amino acids were detected, and the total content was 3.66 mg/g, among which valine was the most at 1.59 mg/g. A total of 13 types of free amino acids were isolated from the 80% EtOH extract, with a total of 17.92 mg/g, of which proline was the most common at 10.96 mg/g. Five essential amino acids were detected, and the total content was 1.50 mg/g, of which valine was the most abundant at 0.56 mg/g. In addition, a total of 4 types of non-protein amino acid derivatives of the hot water extract were isolated, with a total of 1.59 mg/g, of which ?-Aminobutyric acid was the most common at 0.99 mg/g. In the case of 80% EtOH extract, a total of 2 species were isolated, and the total was 1.66 mg/g, and among them, ammonia was the most common at 0.96 mg/g. Therefore, in view of these results, it is believed that the red cabbage leaf hot water and 80% EtOH extract can be used as beauty care functional cosmetic materials for skin and hair care et al., and the results can be used as basic data for research in this field.
