[Solid adsorption and stability of essential oil from pericarp of Gaultheria yunnaensis (Franch.) Rehd].
Experiments have been made on the solid adsorption and stability of the essential oil extracted from Gaultheria yunnanensis. The results show that among the chemical constituents of the oil, methyl salicylate accounts for 99.66%. Grain adsorbents of aluminum hydroxide gel have been proved useful in obtaining higher release rates of the oil at required temperatures as well as keeping the oil stable at room temperature.
