The width of the forest area of Indonesia is about 75% of the entire land which has not been optimally utilized as a raw medicinal resource. The forest area is rich in plants of various medicinal benefit
s which have not been found out and developed. The aim of the study was to explore Central Kalimantan’s forest plants as bioactive compound resources. Using Brine Shrimp Lethality Test (BST) method the
exploration was conducted on 70 kinds of plants which had been traditionally used in that area. The dry powder was macerated inchloroform and then in methanol in order to obtain 140 chloroform and methanol extracts, each 70 extracts respectively. The activities of those extract were tested on 500 dan 1000 ?g/mL of their concentration. The result was analized using probit regresion in order to obtain LC50
value. The result of the study indicated that from those 140 extracts, were obtained 70 active extracts (100?ad larva Artemia salina) in their concentration of 500 ?g/mL. Concentration decreasing up to 100 ?g/mL produced 10 active extracts (100?ad larva A. salina) which potential developed asbioactive compound resources.
