A method for manufacturing an extract of Pogostemoncablin. including carvacrol and thymol is used for solve the problem of the conventional method including complicate purification step to remove a liquid phase extractant. The method includes providing a sample of Pogostemoncablin.. The sample is extracted by supercritical carbon dioxide (SCF CO2) as an extractant at 60℃ and 300-400 kg/cm2 for 120 minutes. The supercritical carbon dioxide is then transformed to a gas phase carbon dioxide (CO2(g)) able to escape. Finally, the extract of Pogostemoncablin. can be obtained.一種含香芹酚及百里酚的左手香萃取液的製備方法，用以解決習知製備方法需要經過繁瑣的純化步驟以移除液態萃取劑的問題。係包含：提供一左手香樣品；於60℃之溫度、300~400kg/cm2之壓力下，以超臨界二氧化碳流體作為一萃取劑以萃取該左手香樣品120分鐘；及使超臨界二氧化碳流體轉變為二氧化碳氣體而逸散，即獲得一左手香萃取液。
