Extracting method of propolis extract capable of reducing the time for extracting propolis and increasing the concentration of artepillin C in propolis extract
The present invention relates to an extracting method of propolis extract, which comprises preparing and crushing a raw block of propolis into a to-be-extracted substance immersing the to-be-extracted substance in alcohol of 95 percent of concentration applying an ultrasonic vibration process to the to-be-extracted substance that is immersed in alcohol for dissolution so as to obtain a crude extract injecting the crude extract into a high pressure supercritical extraction tank for performing an extraction process, wherein the extraction process is performed for 40 minutes to 120 minutes at a pressure in the range of 3600 psi to 4200 psi and a temperature in the range of 40 DEG C and 55 DEG C and separating out a propolis extract by fractionation at a pressure in the range of 1500 psi to 3600 psi, wherein the propolis extract contains artepillin C having a concentration of 2 percent to 10 percent.本發明係關於一種蜂膠萃取物的萃取方法,其包括齊備一蜂膠原塊,並進行破碎成為待萃物;將該待萃物浸泡於95濃度百分比的酒精中;將浸泡酒精之待萃物以超音波震盪法進行溶解獲得一粗萃物;將該粗萃物注入高壓超臨界萃取槽中進行萃取步驟,該萃取步驟之條件為壓力範圍介於3600 psi至4200 psi之間,溫度範圍係介於40ºC至55ºC之間萃取40分鐘至120分鐘;於壓力範圍介於1500 psi至3600 psi之間之條件下分餾析出一蜂膠萃取物,其中該蜂膠萃取物含有濃度為2百分比至10百分比之阿特比靈(artepillin C)。無
