본 실험은 엔디브 양액재배에 적합한 배양액을 조성하고. 새로 조성한 배양액(SCUE)의 효과를 검토하고자 수행하였다. 엔디브 재배에 적합한 배양액을 양수분 흡수율에 의해 조성한 결과 NO3-N 15.0, NH4-N 1.0 PO4-P 3.0. K 10.0, Ca 5.0, Mg 3.5 me.l-1가 적당하였다. 새로 조성한 서울시립대 엔디브액 (SCUE)과 유럽의 엔디브액간의 재배실험 결과, 배양액간의 생육 및 수량은 차이가 없었지만, pH와 EC의 변화폭은 새로 조성한 양액에서 적었다.

Immune-potentiation of Chicorium endivia L. were investigated on follows extracts associated with ultrasonification process at 60 kHz and showed the highest promotion of human B and T cell growth, about 10~20% compared to the control. The secretion of TNF-α and IL-6 was also enhanced by the addition (0.5mg/ml) of the extracts. NK cell activation was Improved up to 1.37 times higher than the control, through adding extracts. It was also found that extracts from C. endivia L. could yield higher nitric oxide production from macrophage than Lipopolysaccaharides (LPS). It can be concluded that, in general, the extracts treated with ultrasonification has higher immune activity than others, possibly by higher yielding immune-modulatory activity than conventional extraction process. The optimum condition for the extraction of C. endivia L. is ethanol extraction at 60~100℃ associated with ultrasonification.
