High Performance Liquid Chromatographic Determination of Pungent Gingerol Compounds of Ginger (Zingiber officinale Roscoe)

ABSTRACT The pungent gingerol compounds of green (4–5 months) and dry (8–9 months) ginger ( Zingiber officinale Roscoe) were extracted by acetone and analyzed directly by high performance liquid chromatography (HPLC) on a reverse phase column (RP‐18). The total gingerol content (6‐, 8‐ and 10‐gingerol) of green ginger ranged from 0.65–0.88% (w/w) while that of dry ginger varied from 1.10–1.56% (w/w).
