Abstract:
This research studied the hydrodistillation of fresh Zingiber zerumbet rhizomes from
Ratchaburi province using Clevenger apparatus to collect oil. From the experiment, 1.22±0.24 mL or 0.81%(v/w) of oil was obtained from the distillation of 150 g of fresh rhizomes. Then, the oil was analyzed by GC-MS, and it was found that there were 6 main compounds consisting of (1S)-Camphene, o-Cymene, 2-Bornanone, Humulene, Camphene, and Zerumbone. Zerumbone was the major compound (43.44%) of the oil which correlated to the previous reported. The oil was prepared in the form of cream form developed from 5 formulas of cream base with NIKKOMULESS LC as emulsifier. According to the results, the formula using NIKKOMULESS LC5% was more stable than those that used NIKKOMULESS LC3%. Among NIKKOMULESS LC 5%, formula 3 gave the best cream texture with smooth sense and was easily absorbed into the skin. Formula 4 and 5 had more amounts of cetostearyl alcohol that was thickening agent and made the cream harder than formula 3. When the Z. zerumbet oil was added into the formula 3 for 1%, 3% and 5% (w/w), 1% of oil preparation gave a white shining color with smooth texture and easy absorption through the skin. In conclusion, this formula can be further developed to an antiinflammatory cream
