          ABSTRACT    OBJECTIVE  To  comprehensively  screen  the  optimal  steaming  time  of  salt-steaming  Morinda  officinalis (SSMO)
          based  on  Q-markers  and  anti-oxidative  activities,  and  to  establish  characteristic  quality  standard  of  the  decoction  pieces.
          METHODS  The  contents  of  six  Q-markers  (1-kestose,  nystose,  1 -fructofuranosylnystose,  inulotriose,  inulotetraose  and
                                                                  F
          inulopentaose) in SSMO at different steaming time were determined by HPLC-ELSD method simultaneously. The activity of sample
          extracts  to  scavenge  4  kinds  of  oxidative  free  radical  and  their  iron  reduction  abilities  were  determined  by  visible  UV
          spectrophotometer.  The  optimal  steaming  time  of  SSMO  was  screened  by  gray  relevance  degree  and  entropy  weight  technique  for
          order preference by similarity to an ideal solution (TOPSIS)-fusion model method. The contents of six Q-markers in 10 batches of
          SSMO  prepared  at  the  optimal  steaming  time  were  determined.  HPLC-ELSD  fingerprints  of  SSMO  decoction  pieces  were
          established. RESULTS The results showed that the contents of six Q-markers were the highest when SSMO was steamed for 3-5 h;
          and the ability of scavenging DPPH·, ABTS·, PTIO·, ·OH and iron reduction ability was the best at 5 h. There were 20 common
          peaks in the fingerprints for 10 batches of samples, and the similarities were higher than 0.990. A total of 9 chromatographic peaks
          were identified, which were D-fructose (peak 1), D(+)-glucose (peak 2), sucrose (peak 3), 1-kestose (peak 4), nystose (peak
          5),  1 -fructofuranosylnystose (peak  6),  inulotriose (peak  X2),  inulotetraose (peak  X3)  and  inulopentaose (peak  X4). Average
               F
          contents  of  six  Q-markers  were  4.17%,  5.54%,  6.60%,  2.89%,  2.62%  and  2.13%,  respectively.  CONCLUSIONS  The  optimal
          steaming time of SSMO is 5 h; the contents of six Q-markers are primarily determined on the basis of dry product, which are no
          less  than  3.03%,  4.11%,  4.87%,  2.15%,  1.96%  and  1.58%,  respectively. The  ratio  of  Inulin-/Inulo  oligosaccharides  content  is  no
                                                              more than 2.5.
