This study was carried out to evaluate the economic value of development of separation and purification techniques of flavonoid in citrus using IRR, NPV. The separation and purification techniques of flavonoid of citrus was developed by national institute of horticultural and herbal science in Korea rural development administration. This technology could be used to improve efficiency and practicality of cultivation of citrus. The research results show that the technological value of separation and purification techniques of flavonoid of citrus was evaluated 3,155(scenario 1)~6,518(scenario 2) million won. IRR was 28.3%~61.2%, which was greater than discount rate(11.9%). NPV is 5,541~18,773 million won. Therefore, the economic validity of development of separation and purification techniques of flavonoid of citrus is identified by the results of technology evaluation.
