초록

홍화꽃이 식품재료적 가치를 높이는 기초적 연구의 일환으로 한국산과 중국산의 화학적성분을 비교 분석한 결과는 다음과 같다. 홍화꽃의 일반성분은 한국산 홍화꽃의 조단백질, 조지 방, 조회분, 조섬유, 무질소물의 함량이 14.70%, 3.10%, 6.90%, 18.20%, 57.10% 이었으며 중국산 홍화꽃은 12.60%, 2.70%, 5.80%, 16.40%, 62.50%로 나타나 무기질소물을 제외하고 한국산 홍화꽃이 중국산 홍화꽃 보다 높게 나타났다. 유리당은 한국산과 중국산 홍화꽃에서 fructose, glucose, sucrose가 대부분이었다. 폴레페놀 함량은 수용성 추출물이 한국산 13.85%, 중국산이 9.39%로 한국산 홍화꽃이 많이 함유되었으며 또한 메탄올 추출물에서도 한국산 홍화꽃이 9.70%, 중국산 홍화꽃이 7.04%로 한국산 홍화꽃이 중국산 홍화꽃보다 비교적 많이 함유되어 있는 것으로 나타났다. 지방산 함량은 한국산 홍화꽃은 포화지방산과 불포화지방산이 6.80%, 93.20% 중국산 홍화꽃은 16.0%, 84.0%로 한국산이 월등히 높은 불포화지방산 함량을 나타냈다. 한국산과 중국산 홍화꽃 모두에서 linoleic acid 와 oleic acid 가 함량이 높게 나타났다. 아미노산중 필수아미노산은 한국산 홍화꽃이 46.67% 중국산 홍화꽃이 36.79%로 한국산 홍화꽃이 높게 나타났으며 모든 필수아미노산 조성이 한국산 홍화꽃에서 높게 나타났다. 그리고 비필수아미노산이 차지하는 비율은 한국산 홍화꽃이 65.17% 중국산 홍화꽃이 54.49%로 한국산 홍화꽃이 차지하는 비율이 필수아미노산과 더불어 높게 나타났다. 무기질은 한국산 홍화꽃이 중국산 홍화꽃에 비해 Ca, Cu, Fe, Mn이 높게 나타났으며 반면에 A1, Ba, Mg, K, Na, Zn, Sr, P은 중국산 홍화꽃에서 더 많은 함량을 나타냈다.

In approximate composition, crude protein, lipid, ash, crude fiber, and N-free extract constituted 14.70%, 3.10%, 6.90%, 18.20%, and 57.10%, respectively, in Korean safflower flowers, compared to 12.60%, 2.70%, 5.80%, 16.40% and 62.50%, respectively, in Chinese safflower flowers. This indicated that Korean safflower flowers surpassed their Chinese counterparts except in terms of N-free extract. Free sugars such as fructose, glucose, and sucrose were proven to be dominant in both domestic and Chinese safflower flowers, while little xylose was contained. For content of polyphenolic compound, Korean safflower flowers contained 13.85% water soluble extract and 9.70% MeOH extract, compared to 9.39% and 7.04%, respectively, for the Chinese variety, confirming the higher levels in the Korean variety. For fatty acids, (Ed- the following results are not presented in ratio form) saturated fatty acids and unsaturated fatty acids comprised 6.80% and 93.20% in Korean safflower flowers and 16.0% and 84.0% in Chinese safflower flowers, respectively. Linoleic, oleic, and palmitoleic acids comprised 75.30%, 11.60%, and 3.40% in Korean safflower flowers, and 66.70%, 11.20%, and 6.10% in the Chinese variety, respectively. Of amino acids, essential amino acids comprised 46.67% in Korean safflower flowers and 36.79% in the Chinese variety. Moreover, total essential amino acids in Korean safflower flowers were higher than those of their counterparts. Non-essential amino acid comprised 65.17% in the Korean variety and 54.49% in the Chinese. In terms of mineral content, Korean safflower flowers contained more Ca, Cu, Fe and Mn than those of China, while Chinese safflower flowers contained more A1, Ba, Mg, K, Na, Zn, Sr and P.
