Abstract: The Chamaecyparis obtusa extract can be extracted by various methods. For instance, an extraction solvent may be applied to leaves, trunks or branches of the Chamaecyparis obtuse for hot water extraction, cold solvent immersing extraction or warm solvent immersing extraction. In this case, the extraction solvent is added to the Chamaecyparis obtuse 2 to 20 times in a weight ratio to then be mixed, followed by extracting at 10 to 150 for 1 to 24 hours. Here, at least one selected from the group consisting of water, C1-C4 lower alcohols, polyalcohols or mixtures thereof may be used as the extraction solvent. The C1-C4 lower alcohols may include methanol, ethanol, and so on. The polyalcohols may include butylene glycol, propylene glycol, pentylene glycol. The mixtures may include a mixture of water and a lower alcohol, a mixture of water and a polyalcohol, a mixture of water and a lower alcohol and a polyalcohol, or a mixture of water, a lower alcohol and a polyalcohol.

Abstract: The present invention relates to a pharmaceutical composition, and to a food composition, for regulating the motility of the gastrointestinal tract, and more particularly, to a pharmaceutical composition, and to a food composition, which use a Chamaecyparis obtusa extract so as to be effective in the prevention and treatment of motility disorders of the gastrointestinal tract. The pharmaceutical composition for regulating the motility of the gastrointestinal tract according to the present invention contains the Chamaecyparis obtusa extract as an active ingredient, wherein the motility of the gastrointestinal tract is regulated by varying the electrical activity of interstitial cells of Cajal. Further, the food composition for regulating the motility of the gastrointestinal tract according to the present invention contains the Chamaecyparis obtusa extract as an active ingredient.
