Abstract

Fruits of mahkotadewa (Phaleria macrocarpa (Scheff) Boerl). has been used to cure various health problems, including empirical treatment for cancer. The therapeutic effect of natural material is related to the chemical compounds it contain. In fruits of Phaleria macrocarpa, various chemicals are present such as flavonoid and tannin, both show anticancer activity, as well as other unknown ones presumably supportive for cancer treatment. An in vitro experiment is therefore set up with the objective of examining the effect of fruit extract on human uterine cervical carcinoma cells (HeLa cells). Various concentrations: 5, 10, 25, 50 and 100 ppm of fruit extract were evaluated. Observations were made 24, 72 and 120 hour after incubating HeLa cells in each treatments. The results showed that fruit might inhibit the growth of HeLa cells. Inhibitory concentration (IC50) of fruit extract after 24 hours of incubation is 6,21 ppm, after 72 hour of incubation is 5,09 ppm dan 5,73 ppm for 120 hour of incubation. Inhibitory potential of fruits in 72 hour of incubation is a highest ones. The effect might be associated to the active compounds contained in these material.

Abstract

The growth responces of potato explant (var. Atlantic), under different temperatures (100C) between photoperiod and dark period air temperatures in culture room, in high intensity of light (7000 lux) and low intensity of light (3000 lux), cultured in 18 h light/dark cycle and incubated for 21 and 28 days wasobserved. The result shown that photoautotroph condition influence the explant growth to be planlet. After 28 days incubation the planlets growth better than in 21 days. Its because the photosynthesis process during 28 days incubation were more effective than in 21 days incubation. The dry weight per planlet, number of leaves, leaf area and dry weight per leaf were enhanced in photoautotroph condition with 7000 lux light intensity in all treatments. In 3000 lux light intensity, the high planlet with small diameter was performanced. The study indicates that the photoautotroph condition affect further growth of the in vitro potato planlet.
