Abstract: The present invention relates to a composition for an inflammatory disease, using Litsea japonica, and more specifically to a composition for preventing and treating an inflammatory disease, containing the oil derived from the fruits or the seeds of Litsea japonica, and a method for preparing the same. The present invention uses the fruits (excluding the seeds) or the seeds of Litsea japonica and obtains the oil, which is used as an active ingredient of a composition for preventing and treating an inflammatory disease, by using n-hexane, wherein the oil is obtained by: separating the fruits (excluding the seeds) of Litsea japonica from the seeds; injecting n-hexane, which is a solvent, into the fruits (excluding the seeds) or the seeds, 9-11 times greater than the weight of each: stirring the same for 24 hours at room temperature and extracting the same; and removing a hexane layer.

Abstract: The present invention relates to a composition for preventing and treating gastrointestinal diseases by using Litsea japonica, and specifically, to a composition for preventing and treating gastrointestinal diseases, containing essential oils extracted from Litsea japonica fruit as an active ingredient. According to the present invention, the essential oils extracted from Litsea japonica fruits (pure fruit, seed fruit, and seeds) and used as the active ingredient of the composition for preventing and treating gastrointestinal diseases have been confirmed to have excellent effects in an efficacy evaluation for relieving gastrointestinal diseases caused by Helicobacter pylori, which is a gastrointestinal disease factor, physical factors induced by stress, and chemical factors induced by indomethacin. Therefore, the essential oils extracted from Litsea japonica fruit (pure fruit, seed fruit, and seeds) are useful for preventing and treating gastrointestinal diseases caused by various factors.
