White turmeric (Curcuma zedoaria (Christm.) Roscoe) has been used as traditional medicine by Indonesian people. The chemical constituents of essential oil of white turmeric were collected in 5 hours of the steam-distillation, and then were investigated by GC-MS. Furthermore, the essential oils were fractionated every hour of 5 hours distillation and were identified twenty compounds. The major compounds of the oil is camphor (49.51 %), isobornyl alcohol (12.66 %), borneol (4.23 %), furanodiene (3.61 %), furanodienone (3.49 %), 1,8-cineole (3.42 %), camphene (2.28 %), β-pinene (1.75 %), 2-nonanon (0.76 %) and germacrene- D (1.19 %). The main component of the essential oils is champhor, which is the highest concentration lie in the 3rd of collection times (50.71 %). The toxicity of the essential oils was subjected toward Artemia salina Leach. The results indicated that the essential oils from 5th of collection times by using steam-distillation have the highest toxicity, and the LC50 value is 3.25 ppm (v/v). The oil might be classified as anti-tumor activity. © 2014 Har Krishan Bhalla & Sons.
