Abstract
Free radical contamination is very dangerous for health. Perfume contains essential oils whose components are potential as antiradical. Antioxidant perfume is a perfume made from essential oil with a certain concentration which is very effective to reduce free radicals in the air. This study aims to determine the effectiveness of essential oils as antiradical compounds using laboratory experiments in the reduction of free radical concentration of DPPH with various concentrations of fruit extract which containing terpenoid component. DPPH concentration changes in the air followed by using electronic nose (E-Nose) equipped with multisensory gas. The experimental results showed that the critical concentration of fruit extract which effectively decreased free radical i.e. apple, orange, grape, melon, and lemon were 7.47%, 6.21%, 15.61%, 7.58%, and 6.22%. The greater concentration of these critical concentrations of fruit extracts is potentially as prooxidants.

Summary
Free radicals are potentially damaging to the environment and human health. Because when free radicals enter the body, it will rapidly attract biological macromolecules electrons that surround proteins, nucleic acids, and deoxyribonucleic acids (DNA) which interfere metabolic processes in the body [1]. It is known that various types of volatile non-methane organic compounds from different vegetation have been emitted into the atmosphere every day. These organic compounds include isoprene, monoterpene C10H16, sesquiterpene C15H24, as well as the number of oxygenated compounds such as methanol, hexene, 2-methyl-3-buten-2-ol, and 6-methyl-5-hepten-2. The organic compound with free radical is hydroxyl (OH), nitrate (NO3) and ozone (O3) which the reaction reacts to the lower layer of the troposphere [2]. Different half-life times, for example linalool a monoterpene often found in perfume products, has a half-life of 52 minutes with OH radicals, 55 minutes with ozone and 6 minutes with NOx. Limonene has a citrus scent having a half-life of 49 minutes (OH), 2.0 hours (O3) and 5 minutes (NOx) [3]
