          ABSTRACT    OBJECTIVE To study the extraction and enrichment technology of chrysosplenides A (CA) and I (CI) in Tibetan
          medicine  Chrysosplenium  axillare.  METHODS  HPLC  method  was  used  to  determine  the  contents  of  CA  and  CI.  The  orthogonal
          experiment  was  used  to  optimize  the  extraction  technology  of  CA  and  CI  in  C.  axillare  using  total  transfer  rate  of  CA  and  CI  as
          evaluation  indexes,  with  volume  fraction  of  ethanol,  extraction  temperature,  extraction  times  and  solid-liquid  ratio  as  factors. The
          validation test was also performed. The enrichment technology of CA and CI in C. axillare was optimized using D101 macroporous
          adsorption resin as adsorbent, total contents of CA and CI as evaluation indexes, with the volume fraction and dosage of eluent for
          impurities and target components. The validation test was also performed. RESULTS The optimum extraction conditions of CA and
          CI  from  C.  axillare  were  as  follows:  the  medicinal  powder  of  C.  axillare  was  extracted  by  ultrasound  at  room  temperature  for  45
          min at one time with 8 times of 50% ethanol. Results of validation tests showed that total transfer rate of CA and CI in C. axillare
          was 95.43% in average (RSD=1.02%, n=3). The optimal enrichment technology was as follows: the sample solution was added
          into D101 macroporous adsorption resin column and stood for 1 hour; the impurities were eluted with 20% ethanol 4 BV (column
          volume), and CA and CI were eluted with 50% ethanol 4 BV. The results of validation tests showed that total content of CA and CI
          was  322.7  mg/g  in  average (RSD=1.05%,  n=3),  with  average  enrichment  multiple  of  11.61  times.  CONCLUSIONS  The  study
          has successfully optimized the extraction and enrichment technology of CA and CI from C. axillare, and can provide reference for
                                                              the development and utilization of CA and CI.
