[Study on Chemical Composition of Zingiberis Rhizome Carbonisata]
Objective:
To study the chemical constituents from Zingiberis Rhizome Carbonisata. g.
Methods:
Compounds were isolated by Sephadex LH-20,ODS,MCI and silica gel column chromatography. Their structures were elucidated by physicochemical property and spectral analysis.
Results:
16 compounds were isolated and identified as sitost-5-en-3β-ol acetate( 1),dibutyl phthalate( 2),4-[2-( 5-butylfuran-2-yl) ethyl]-2-methoxyphenol( 3),β-sitosterol( 4),8-paradol( 5),10-gingerdione( 6),6-shogaol( 7),6-paradol( 8),3,5-diacetoxy-6-gingerdiol( 9),1,2-benzenediol( 10),zingiberone( 11),6-gingerol( 12),1,2,4,5-tetrahydroxybenzene( 13),stigmasterol acetate( 14),8-dehydrogingerdione( 15) and 3,5-diacetoxy-7-( 4-hydroxy-3-methoxyphenyl)-1-( 4,5-dihydroxy-3-methoxyphenyl) heptane( 16).
Conclusion:
All the compounds are isolated from Zingiberis Rhizome Carbonisata for the first time. And compounds 2,10,11,and13 are generated in the process of processing.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
