essential oil with anti-
dandruff activity and a preparation method and application thereof. The preparation method comprises 1)
drying and
grinding Zingiber corallinum Hance residues to obtain
Zingiber corallinum Hance residue
powder, 2) carrying out high temperature sterilization on the Zingiber corallinum Hance residue
powder at 121 DEG C for 30min, then carrying out cooling and taking out the Zingiber corallinum Hance residue
powder, 3) adding 0.1% of powder of
lactic acid bacteria and 20 times by weight of water into the Zingiber corallinum Hance residue powder subjected to sterilization and cooling, carrying out sealing and carrying out
continuous fermentation at 40 DEG C for 6d, 4) after the
fermentation is completed, taking out a sample and carrying out
drying in a water bath at 45 DEG C to obtain fermentative Zingiber corallinum Hance residue powder, 5) adding the fermentative Zingiber corallinum Hance residue powder into 25 times by weight of
distilled water, carrying out immersion for 1.0-1.5h, carrying out
steam distillation, collecting the distillate, adding NaCl into the distillate, carrying out extraction through a lipophilic
organic solvent 3 times and collecting organic extract, and 6)
