    Abstract:

    Angelica keiskei is a kind of high nutritional vegetable used as both food and medicine. In this study，single factor experiment and orthogonality test were developed to optimize the extraction process of 4-hydroxyderricin（4-HD） and xanthoangelol（XAG），from Angelica keiskei . The optimized extraction conditions were as follows：times of extraction，2 times；extract solvent，80% ethanol；extraction temperature，55 ℃；extraction time，90 min；ratio of solid to liquid，1∶10. Under these optimized conditions，the extraction yield of 4-HD and XAG were 1.82 mg/g and 2.12 mg/g，respectively. Further，isolation and purification of 4-HD and XAG by silica gel column and semi-preparative C18 column was also described，and then the structures and purities were identified by HPLC-MS and NMR. Results showed that 4-HD at 99.08% purity and XAG at 98.92% purity were obtained.
