摘要
以石油醚为溶剂采用索氏提取法提取罗汉果种仁油脂,采用HPLC检测,初步确定罗汉果种仁中含有角鲨烯,含量为12.5%。经柱层析、HPLC制备后得纯度为98.5%的化合物单体,经IR、1H-NMR、13C-NMR、MS检测,确认罗汉果种仁油中含有角鲨烯。
The seed oil of Siraitia grosvenorii was extracted by Soxhlets extractor with petrolether, squalene was qualified by HPLC at the first step and purified by silica gel column. The content was 12. 5%. The purity was more than 98.5 % by HPLC preparation. Squalene is identified by IR, ^1 H-NMR, ^13 C-NMR, MS in the S. grosvenorii seed oil.
