The extraction efficiency of orange-yellow pigment from the Gardenia was greatly depended upon the extraction time, extraction temperature, volume of solvent used and fat contents of the Gardenia. From the experimental results, the amounts of extracted pigment (P) was proportional to the $log\;t^{\;1{\cdot}15}$ of extraction time$(t;\;0{\sim}60\;min.)$, the $log\;T^{3{\cdot}73}$ of extraction temperature$(T;\;5{\sim}60^{\circ}C)$, the $log\;S^{3{\cdot}7}$ of volume of solvent$(S;\;5{\sim}50\;ml)$, and the -4X of fat contexts of sample $(X;\;0{\sim}0.\;15)$ at $18^{\circ}C$ for 10 minutes. Finally, the modified empirical equation was derived as follow; $P{\simeq}1.15\;log\;t+3.73\;log\;T+3.7\;log\;S-4X-6.4$ In addition to that, the most optimum conditions of pigment extraction were determined as 30 minutes of operation time, $40^{\circ}C$ of temperature. Deffated Gardenia was more productive than natural Gardenia in the pigment extraction.
