摘  要：
为了研究常温高压超临界CO_2提取法提取灵芝三萜和甾醇成分的效果,采用不同高压的超临界CO_2提取法提取灵芝细粉中灵芝三萜和甾醇成分,通过高效液相色谱(HPLC)测定灵芝三萜和甾醇的含量,并与传统的乙醇回流提取法进行比较。研究表明,高压超临界CO_2提取工艺条件为:提取压力85 MPa,提取温度50℃,提取时间4 h,在此条件下灵芝三萜含量为1.35%,麦角甾醇含量为0.32%,而采用乙醇回流提取法提取的灵芝三萜含量为0.92%,麦角甾醇含量为0.2%。与传统乙醇回流提取法相比,采用高压超临界CO_2提取法,灵芝三萜含量提高了46.7%,麦角甾醇含量提高了60%。HPLC图谱表明,高压超临界CO_2提取法的提取物中三萜和甾醇不仅含量高,而且成分种类多。因此高压超临界CO_2提取法具有得率高、提取温度低、提取时间短等优点,为灵芝成分的提取提供了新技术。

摘  要：
In order to study on the effect of the extracting of triterpenes and sterols by supercritical CO_2 under normal temperature and high pressure, the extraction of Ganoderma lucidum powder was performed by supercritical CO_2 under different pressures. High performance liquid chromatography(HPLC) was used to determine the content of triterpenes and sterols and compared with the traditional method of ethanol reflux extraction. Extraction technology of supercritical CO_2 under high pressure was that extract pressure was 85 MPa, extraction temperature was 50℃, extraction time was 4 h, under the conditions, the contents of triterpenes and ergosterol of G. lucidum were 1.35% and 0.32%, respectively, while the contents of triterpenes and ergosterol by ethanol reflux extraction were 0.92% and 0.2%, respectively. Compared with the traditional ethanol reflux extraction, the content of triterpenes and ergosterol by the extraction of supercritical CO_2 under high pressure was increased by 46.7% and 60%, respectively. The results of HPLC showed that the triterpenes and sterols in supercritical extracts were not only high in content but also in many kinds. The extraction of supercritical CO_2 under high pressure has the advantages of high yield, low extraction temperature and short extraction time, which provides a new technology for the extraction of G. lucidum components.
