Comparision of Chemical Components of Ligusticum chuanzxiong HORT and Cnidium officinale MAKINO

토천궁과 일천궁의 화확성분 비교

Chemical components of domestic Ligusticum chuanxiong HORT and Cnidium officinale MAKINO were analyzed. Proximate analysis of each species showed crude protein 18.5% and 11.1%, crude lipid 5.9% and 6.2%, crude fiber 6.4% and 6.5%, crude ash 5.4% and 6.0%, and carbohydrate 63.7% and 70.2%, respectively. Contents of potassium which was found to be the most abundant mineral in both species were 1.8% and 3.0%, and those of sucrose were 0.4% and 0.3% respectively while neither fructose nor glucose were detected in each species. Major fatty acids in Ligusticum chuanxiong HORT and Cnidium officinale MAKINO were linoleic acid (60.7% and 61.2%), oleic acid (19.9% and 21.3%), palmitic acid (11.4% and 11.3%)(respectively) but there was no significant difference between two species. Glutamic acid was revealed as the most abandant amino acid in both species with 2.5% in Ligusticum chuanxiong HORT and 1.6% in Cnidium officinale MAKINO. Ligusticum chuanxiong HORT and Cnidium officinale MAKINO also were shown to be contained 0.0009% and 0.0005% vitamin $B_1$, and 0.6% and 0.7% tannin, respectively.

토천궁과 일천궁이 한방이나 가공시 기초 자료로 활용될 수 있도록 기본적인 화학 성분을 분석하였다. 일반성분은 토천궁이 조단백 함량이 높았으며, 무기질은 일천궁이 토천궁에 비해 칼륨과 나트륨이 높은 반면, 그외는 토천궁이 전체척으로 높았다. 유리당 조성은 sucrose만 검출되었고, fructose와 glucose는 검출되지 않았다. 지방산 조성은 linoleic acid, oleic acid, palmitic acid, linolenic acid 순으로 구성되었고, 토천궁과 일천궁의 주요 구성아미노산은 글루탐산, 아르기닌, 아스파르트산, 발린 순으로, 대부분 필수아미노산도 고루 분포되어 있었다.
