The invention discloses a method for extracting guaiacol hydrocarbon from chamomile,The method comprises the following steps: (1) placing chamomile in a reactor and adding water for distillation,Take the oil-like substance from the upper layer,Vacuum fractionation,The fraction containing the required guaiacol hydrocarbon was obtained；(2) The fraction obtained in step (1) is dehydrogenated,After cooling, filtrate is obtained by suction filtration；(3) Cool the filtrate to 30-40 ℃,Add petroleum ether and acid solution close to the temperature,After shaking and mixing, it shall be placed and stratified,Repeatedly wash and extract the acid solution with petroleum ether and ice water,The blue solution layer is combined and washed with sodium hydroxide solution,To get a dark blue oil,That is to say, it is the required crude product of guaiac blue hydrocarbon.The invention not only provides a method for extracting pure natural guaiac blue oil hydrocarbon from natural plants, but also provides a high purity guaiac blue oil hydrocarbon crude product and improves the yield of guaiac blue oil hydrocarbon.本發明公開了一種從洋甘菊中提取愈創藍油烴的方法，其包括以下幾個步驟：(1)取洋甘菊置於反應釜中加水蒸餾，靜置取上層油狀物質，減壓分餾，得到含有所需愈創藍油烴的餾分；(2)將步驟(1)中獲得的餾分進行脫氫處理，冷却後抽濾得到濾液；(3)冷却所述濾液至30‑40˚C，並加入接近溫度的石油醚及酸性溶液，震蕩混勻後靜置分層，取所述酸性溶液反復以石油醚和冰水洗滌並萃取，合併藍色溶液層後以氫氧化鈉溶液洗滌，得到深藍色油狀物，即爲所需的愈創藍油烴粗品。本發明不僅提供了一種自天然植物中提取純天然愈創藍油烴的方法，且所提取得到的愈創藍油烴粗品純度較高，提高了愈創藍油烴的收率。
