| Summary, etc. |
… Etlingera or “kantan” is a part of vast Zingiberaceae family . In the Malesian region, a floristically distinct region there are 600 species encompassing 24 genera. The commercial value of the family arises from its utility as ingredients of flavoring, colors and fragrance. The highest content of oil is usually in the rhizomes of this plant. Essential oils gradually loose freshness upon standing. The quality of the essential oil can be monitored by several methods. Gas chromatography-mass spectrometry (GC/MS) is the most common tool used in quality control today. The rhizome samples of Etlingera sp. 3 is collected from a nearby forest in Bentong, Pahang. Pre-treatment of the sample prior to extraction is done stages. The stages comprise of washing, drying, and grinding to fine pieces. The extraction of essential oil from the rhizome material of Etlingera sp. 3 is obtained by hydro-distillation. Method of analysis of the essential oil is using GC-MS, and monitoring the effect of storage, i.e., effect of exposure to light and air, and standing, on the quality of the essential oil. The quality of Etlingera sp.3 essential oil as monitored by GCMS shows degradation upon exposure to heat and light. Certain compounds degrades drastically while others steadily declines as can be seen further in the discussion. In order to preserve its quality and effectiveness it is best kept at its optimum storage condition which is refrigerated in a dark bottle under -4 degrees Celsius.-Author |
