          5.780 8、4.290 3;不同产地灵芝样品一测多评法所得含量与外标法的相对误差均在±12%之内。结论  以灵芝酸A为内参物同时
          测定灵芝中10种灵芝酸类成分含量的一测多评法是可行的,该方法准确性和重复性良好,可用于灵芝的质量控制。

          ABSTRACT   OBJECTIVE  To  establish  a  quantitative  analysis  of  multi-components  by  single  marker (QAMS)  method  for
          simultaneous determination of 10 ganoderic acids in Ganoderma lucidum. METHODS Using ganoderic acid A as internal reference,
          high-performance  liquid  chromatography (HPLC)  method  was  adopted  to  calculate  relative  correction  factors  of  the  other  9
          components,  such  as  ganoderic  acid  B,  ganoderic  acid  C2,  ganoderic  acid  D,  ganoderic  acid  F,  ganoderic  acid  H,  ganoderenic
          acid A, ganoderenic acid B, ganoderenic acid C, ganoderenic acid D; the contents of above ganoderic acids were calculated with
          relative  correction  factors,  and  compared  with  the  results  of  external  standard  method.  RESULTS  The  linear  relationship  of
          ganoderic  acid A,  ganoderic  acid  B,  ganoderic  acid  C2,  ganoderic  acid  D,  ganoderic  acid  F,  ganoderic  acid  H,  ganoderenic  acid
          A,  ganoderenic  acid  B,  ganoderenic  acid  C  and  ganoderenic  acid  D  were  0.032-3.996,  0.040-4.971,  0.037-4.568,  0.028-3.558,
          0.033-4.177,  0.044-5.440,  0.032-3.944,  0.040-4.994,  0.045-5.593  and  0.035-4.342  mg/mL (all  R ≥0.999  2),  respectively.  RSDs
                                                                                     2
          of  precision,  stability (24  h)  and  reproducibility  tests  were  all  lower  than  2%.  Their  average  recovery  rates  were  99.43%,
          100.25%, 98.50%, 99.88%, 100.59%, 99.64%, 98.50%, 99.40%, 99.64% and 99.76%, respectively (RSD<2%, n=6). Relative
          correction factors of ganoderic acid B, ganoderic acid C2, ganoderic acid D, ganoderic acid F, ganoderic acid H, ganoderenic acid
          A, ganoderenic acid B, ganoderenic acid C and ganoderenic acid D were 1.788 5, 1.288 2, 1.126 4, 1.698 5, 0.885 4, 5.468 1,
          4.210  9,  5.780  8,  4.290  3,  respectively.  Relative  errors  between  the  content  obtained  by  QAMS  method  and  external  standard
          method for G. lucidum from different origins were within ±12%. CONCLUSIONS  It is feasible that the contents of 10 ganoderic
          acids  are  determined  simultaneously  by  QAMS  method,  using  ganoderic  acid  A  as  internal  reference.  This  method  shows  good
          precision and reproducibility and can be used for the quality control of G. lucidum.
