|
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.
