Judul: Profil kimiawi dari formula ekstrak meniran, kunyit, dan temulawak berdasarkan toksisitas terbaik
Abstrak: Phyllantin, turmeric and curcuma that known have antioxidant, antitumor, anticancer, and antibacterial activity. They are commonly used as single extract. Mixing two components of medicinal plant extracts can increase the bioactivity. The aim of this research was to know toxicity of phyllantin, turmeric and curcuma through Brine Shrimp Lethality Test and to know the profiles of TLC and FTIR that formula. Phyllantin, turmeric and curcuma was extracted with ethanol. Extract was made into seven formulation with 1:1:1; 1:1:0; 1:0:1; 0:1:1; 1:0:0; 0:1:0; 0:0:1 compilation. Toxicity of formulation was known through Brine Shrimp Lethality Test. Three best extract with the lowest LC50 were taken to define their chemical’s profile using TLC and FTIR. The best three extract were phyllantin:turmeric:curcuma in 0:0:1, 0:1:0, and 0:1:1, with LC50 17.94567, 20.09533, 37.66333 ppm, respectively. Phyllantin:turmeric:curcuma in 0:0:1 show TLC profile with thinner spot and without C=O bond for FTIR spectrum as the other two exctract have thick spot and have C=O bond.

Abstrak: Turmeric, curcumin, and phyllantin are one of medicinal plants that has high potency to be explored nowadays. This research was done to determine the toxicity effects from turmeric, curcumin, and phyllantin mixed extract, and also to define the mixed extract chemical’s profile with KLT and FTIR. Mixed extract were made by mixing turmeric, curcumin, and phyllantin in seven different composition, that were 1:1:1; 1:1:0; 1:0:1; 0:1:1; 1:0:0; 0:1:0; 0:0:1. Then its toxicity effect were measured by exposing Artemia salina to the extract for 24 hours. Three best extract with the lowest LC50 were taken to define their chemical’s profile using TLC and FTIR. The best three extract were tumeric: curcumin: phyllantin mixture extract in 1:1:1; 1:1:0; and 1:0:1 proportion, with LC50 5.5377 ppm, 16.3763 ppm, and 11.6243 ppm, respectively. Mixed compound extract with high biological potential (5.537 ppm) show TLC profile with thick spot and without C≡C bond for FTIR spectrum as the other two exctract have thinner spot and have C≡C bond.
