Infra red and ultra violet spectra study of essential oils from tubber root (Cyperus Rotundus Linn.) Background: Tubber roots (Cyperus rotundus Linn.) has long been known as Indonesian original drug for centuries and used widely by the people of Indonesia. However, until now only few research has been done on tuber roots based on its function as a traditional medicine. The essential oils within tubber roots is suspected has potential role for traditional medicine. The purpose of this study is to determine the profile of infrared and ultra violet (UV) spectra of the tubber. Method: The research was a descriptive research. Extraction of essential oil from tubers puzzles using Soxhlet method with petroleum ether solvent. To get the best fraction analysis was carried out by column chromatography. All fractions were then separated by thin layer chromatography (TLC) and collected by extracting with chloroform. Chloroform extract was evaporated and dissolved in methanol and analyzed by infra red (IR) and UV spectrophotometer. Result: The infrared spectra indicate that there was a volatile oil absorption characteristics of aromatic compounds and functional groups C=O and CH3. In addition, there was an absorption which showed the C-C binding, C-H, and C-CH. UV spectra showed that there were two peaks at a wavelength of 204 nm and 249 nm. Conclusion: Infrared and UV spectra show that the structure of essential oils contained in the bulb puzzle has similarities with the structure of the compound a-cyperone.
