Background : The purpose of this study was to evaluate methods to high quality medicinal vegetables, thereby increasing farm income. This study investigated the effects of different organic fertilizer and applicated cultivation on stable foliage production in Peucedanum japonicum Thunberg. Methods and Results : method of application with organic fertilizer were conducted under nine condition compose to control(non application), N-P2O5-K2O (20-12-10)㎏․10 a−1, Hyphal incubation compost(HIC) applied at 851㎏․10 a−1, Hangawi organic compost(HOC) applied at 547㎏․10 a−1, Fermented mixed oil cake compost(FMOC) applied at 380㎏․10 a−1, 60% and 40% of basal fertilizer in March 12, top dressing were four application in April 12, May 12, June 13 and July 12, respectively. Sowing dates were March 23, 2015. Plants were spaced 15 ㎝ apart in rows 15 ㎝ apart with open cultivation. Conclusions : chemical fertilizers < hyphal incubation compost < hangawi organic compost < fermented mixed oil cake compost application, top dressing than 60% in order of 40% additional fertilizer, aerial part as a result were so many such amount of growth as number of leaf per plant, etc., Green leaf yields is untreated control plot (875 kg․10 a−1) compared to 12% from using chemical fertilizers, HIC application 18% higher, HOC application 20% higher, and FMOC application increased to 28% of the most.

Total phenolic content, total anthocyanin content and antioxidant activity were analyzed from rice samples collected in Korea, Japan and China. The results showed that the total phenolic content and free-radical scavenging activity differed significantly in these rice lines. The correlation between content and activity was subsequently investigated. The results showed that in black rice, anthocyanin was the major phenolic component and that both phenolic content and anthocyanin content were closely correlated with free-radical scavenging activity. Reverse Phase High Performance Liquid Chromatography (RP-HPLC) data showed that cyanidin-3-O-glucoside and peonidin-3-O-glucoside composed about 90% of the total anthocyanin content in black rice and in red rice. In the red rice extract, the total phenolic content produced a high correlation coefficient with antioxidant activity but correlated very poorly with the total anthocyanin content. The OD458 and the OD500 values which represent the proanthocyanidin content of the rice extract, produced high correlation coefficients with antioxidant activity and total phenolic content. These results suggest that the OD458 and the OD500 values can be used to evaluate the quality of red rice. In addition, based on the data obtained, a competitive accumulation model of anthocyanin and proanthocyanidin in black and red rice was proposed.
