Abstract
Ningsih V, Nugraheni ER, Astirin OP. 2013. Toxicity test of active fraction from ethanol extract of ginje (Thevetia peruviana) leaves by Brine Shrimp Test method and chemistry compound profile of most active fraction. Biofarmasi 11: 48-57. Cancer is a major threat to human health. The treatment that been made such as dissection, radiation, and chemotherapy, did not give satisfactory results, even gave the considerable adverse side effects. Other alternative that selected is utilizing the natural materials from plant that expected to be companion chemotherapy. One of the plants as source of new drug potentially is ginje (Thevetia peruviana Merr). Previous studies reported that ethanol extract of ginje leaves have toxic effects below 1000 µg/mL. Therefore, it needs to be tested further to determine its potential as anticancer. This study aimed to determine the toxic effects of the active fractions of ethanol extract of ginje leaves by Brine Shrimp Test (BST) method and to determine the profile of active fraction of chemical constituents. Toxicity test was performed with Brine Shrimp Test (BST) method against Artemia salina Leach. Shrimp larva with a series concentrations extract of 62.5 µg/mL, 125 µg/mL, 250 µg/mL, 500 µg/mL and 1000 µg/mL of each concentration were tested in 5 flacons. Each flacon contained 10 shrimp larva. The percentage of shrimp larva mortality was calculated after 24 hours of test and the data were analyzed by calculating the value of LC50. The profile of the chemical contents of the most active fraction were identified by TLC and analyzed qualitatively. The results showed that the most active fraction in killing the larva of shrimp Artemia is the fraction I with the values of LC50-24 hours was 44.67 µg/mL. The contents of chemical compounds contained in fraction I of leaf ethanol extract of ginje were terpenoid and phenolic groups.
