| Optimal conditions for the seed germination and growth of Hedyotis diffusa were studied. As photoperiod was increased from 12 hr to 24hr, the germination rate of Hedyotis diffusa was gradually increased. The photoperiod and temperature inflenced on the fermination synergistically. After the growth of 20 weeks under the natural condition (June~Oct.), the length of H. diffusa was $38.9{pm}4.2cm$ (15.5~52.5cm), and total dry weight per $3.3m^2$ was $316.7{pm}10.3g$. It is considered that H. diffusa could be cultivated in a part of inland. The anticancer effect of H. diffusa extract was examined. F-344 rats aged 6 weeks were divided into 3 groups and were given an I.P. of diethylnitrosamine at 200mg/kg body weight as a promoter, initially. And in two weeks after the beginnign of the experiment, group 1 was supplied iwth feed containing 0.02% 2-AAG as a promoter for 6 weeks. Group 2 was supplied with feed containing extracts of H.diffusa (0.02%) for two weeks. Group3 was supplied with only basal diet. All rats were sacrificed for partial hepatectomu, and the antipromoting effect was examined by the number 문 area per $cm^2$ of foci in river. In group 1, the number of hyperplastic nodule was $18.5{pm}7.7$, but in group2, it was drastically reduced to $10.3{pm}1.8$ rather thn those of group1. The total area of nodules $(mm^2)$ /whole liver $(cm^2)$ of group 1 and group2 were $19.2{pm}7.7$ and $5.0{pm}3.2$, respectively. These results indicate that extract of H.diffusa act as an anticancer agent at statistically significant level (p<0.001). |
