The Study Of Chemical Composition Of North And South Fruit Of Chinese Magnoliavine

The chemical composition of north and south fruit of Chinese magnoliavine was studied in this paper. Polysaccharide content and stability of erythrophyll were determined by Ultraviolet Spectrophotometry. Fatty acids and volatile oil constituents of north and south fruit of Chinese magnoliavine were analyzed and compared by Gas Chromatograph-Mass Spectrometry. Using high-performance liquid chromatography(HPLC) to do a quantitative analysis fruit of Chinese magnoliavine of deoxyschizandrin.The polysaccharide was extracted by Ultrasonic method. The optimum extraction conditions are as follows: solid and liquid ratio is 1:30, ultrasonic time is 30 minute, ultrasonic temperature is 30 oC, ultrasonic times are 2. The polysaccharide is determined used glucose as standard by Ultraviolet Spectrophotometry.Fruit of Chinese magnoliavine erythrophyll is a kind of natural pigment, and it has good stability. The researching indicate that it has a broad development prospect.The soxhlet extraction method was used to extract fatty acids in fruit of Chinese magnoliavine, and determined them by GC-MS The result indicated that the fatty acids mostly were 9,12-Octadecadienoic acid and north fruit of Chinese magnoliavine was higher than south .The highest content was 68.58 % in Liaoning, the lowest content was 40.08 % in Yunnan.The simultaneous distilled extraction method and wet distillation are used to extract volatile oil. The compositions of voilatile oil are mostly alcohol, aldehyde, ketone, ester compounds and alkyl compounds Their compositions are different because of different vegetations and producing areas. Principal constituent of voilatile oils are terpenoids for fruit of Chinese magnoliavine. Molecular weight of monoterpenoid is 136, molecular weight of sesquiterpenes is 204.Fruit of Chinese magnoliavine liquors were studied by solid phase extraction and traditional extraction. The method of solid phase extraction was better than traditional extraction.Fruit of Chinese magnoliavine deoxyschizandrin determined by HPLC.The experiment indicate that the south is higher than the north.
