[Chemical constituents of rhizomes of Zingiber officinale].
OBJECTIVE
To investigate the chemical constituents from the rhizomes of Zingiber officinale.


METHODS
Isolation and purification of the chemical constituents were carried out on the column chromatography of silica gel and Sephadex LH-20. The structures were elucidated on basis of physicochemical properties and spectral data.


RESULTS
Ten compounds were isolated and identified as beta-sitosterol palmitate (1), isovanillin (2), glycol monopalmitate (3), hexacosanoic acid 2,3-dihydroxypropyl ester (4), maleimide-5-oxime (5), p-hydroxybenzaldehyde (6), adenine (7), 6-gingerol (8), 6-shogaol (9), and 1-(omega-ferulyloxyceratyl) glycerols (10a-10f).


CONCLUSIONS
Compounds 1-7 and 10a-10e are obtained from Z. officinale for the first time, and compound 10f is a new compound.
