Abstract

Changes in the contents of total phenolic compounds in as Orostachys japonicus well as their antioxidant capacity according to the control of night-break, day-length control, variation in luminosity and amount of fertilizer used were examined. The results were compared with those obtained from wild Orostachys japonicus. The contents of the total phenolic compounds in Orostachys japonicus were roughly proportional to the increasing level of irradiation and nitrogen fertilization. The total content of phenolic compounds in the wild Orostachys japonicus of was higher than cultivated under various conditions. The antioxidant capacities of the Orostachys japonicus were increased roughly with increasing level of irradiation and nitrogen fertilization. Overall, the total content of phenolic compounds of Orostachys japonicus and their antioxidant capacity were not significantly affected by the amount of phosphorus and potassium fertilizer used.

바위솔 총 페놀 함량은 조사된 빛의 양 및 질소비료의 시비량과 밀접한 관계가 있으며 빛의 양이 증가될수록 질소비료의 시비량이 증가할수록 총 페놀 함량이 증가하는 경향이 관찰되었다. 총 페놀 함량은 여러 가지 조건하에서 인공적으로 재배된 바위솔보다 자연산 바위솔에서 높은 것으로 조사되었다. 자연산의 경우 개화 후의 총 페놀 함량이 개화 전의 총 페놀함량보다 높았다. 바위솔의 항산화능은 바위솔에 조사된 빛의 양 및 질소비료의 시비량과 관계가 있으며 빛의 양 및 질소비료의 시비량이 증가하면 대략적으로 항산화능도 증가하는 것으로 조사되었다. 인산 및 칼륨비료의 시비량과 총페놀 함량과 항산화능 사이에는 별 큰 상관관계가 없는 것으로 관찰되었다.
