Vinegar Curcuma Chemical Composition And Antioxidant Activity

The Curcuma aromatica Salisb is the the dry rhizome of The Curcuma aromatica Salisb (Curcuma wenyujin Y.H.ChenetC.Ling), It can be used to treat abdominal pain due to blood stasis,liver splenomegaly,menopause that caused by ecchymosis and diet agglomeration.The property of the Curcuma aromatica Salis that boiled by vinegar is to alleviate,,and it is used widely..This topic make sure the best extraction process of the naphtha,curcumin and amylose that estracted from the Curcuma processing with vinegar by orthogonal experimental design. We used the method of steam distillation to extract the naphtha,and the best condition is 20 items, the immersion time is 8 hours, the extraction time is 10 hours; The curcumin is estacted with elchohol by circumfluence,the best condition is the ethyl alcohol density 80%, the extraction time 1 hours,and for 3 times;The amylose is extracted by conclusion:alcohol sedimenting technique,the best condition is l water`s volumn 20 items,each time decoction time 1 hour, decoction 3 times..Comparative studied on the chemical composition of the naphtha,curcumin and amylose that extracted from the Curcuma processing with vinegar and the nature Curcuma. the result indicates the Beta - the pinene, Beta - the elemene, germacrone, the phthalic acid diethyl ester in the naphtha of two species Curcuma aredifferent. This five kinds of compound peak area sum total occupies the the Curcuma processing with vinegar volatile constituent total peak area separately 85.20%, lives the warm e technique volatile constituent total peak area 43.68%. the nature Curcuma`s volatile constituent total peak area 43.68%. And the Beta - elemene`s content in the Curcuma processing with vinegar comparaed with the nature Curcuma`s 1.32% rises to 33.88%; the phthalic acid diethyl ester content by 1.76% rises to 26.13%.Simultaneously the resault indicated the curcuma composition approximately of the Curcuma processing with vinegar is two times of the nature Curcuma`s. The amylose composition approximately is a little less than the nature Curcuma`s.The method of the DPPH free radical elimination synthesis to compare thenaphtha,curcumin and amylose composition approximately`s antioxidative activity of the Curcuma processing with vinegar and the nature Curcuma, The result indicated that these three kinds of chemical compositions have the varying degree oxidation resistance ability, its oxidation resistance ability`s order is flavine > volatile oil > polysaccharide.Established Cuzhu Processing Curcuma technical specifications and quality standards, quality control of Chinese herbal medicines and proprietary Chinese medicines slices provide a reliable basis...
