The Study Of Some Active Material In The Different Organs From Magnolia Grandiflora

Magnolia grandiflora is widely planted in our country,rich in resources.The exploitation of its flower is widespread at home and abroad,the leaves and fruits section also contains a large number of active substances.This experiment use the different organs in Magnolia grandiflora: analyzing and comparing of the essential nutrients in different organs from Magnolia grandiflora; extracting and analyzing aroma components in the oil from different seasons magnolia leaf and comparing the changes of the type and content of oil aroma components in each season; extracting and analyzing the oil aroma components of magnolia grandiflora flower, and the other two plants of Magnolia category:Magnolia denudata 、 Magnolia liliiflora, then comparing the difference and connection of the type and content of oil fragrance ingredient in leaf from different flower;Extracting and analyzing the fatty acid composition of magnolia fruit section and optimizating the process of extracting flavonoids.The main findings are as follows:1 Essential nutrients content in different organs of magnolia grandiflora vary greatly.2 The content of β-elemene in each season magnolia grandiflora leaf oil is highest,and it achieves maximum(40.56%)when summer comes,the essential oil of Summer leaf has the least number of compound classes,contrastly,the winter leaf has the largest munber of compound classes in its oil.At the same time,the species of its esters is significantly higher than the other three periods.3 The essential oil fragrance ingredientof the three plants flower from Magnoliaceae Magnolia has similarities to a large extent, but the main ingredient is slightly different,the main ingredient of Magnolia grandiflora flower oil isβ-gurjunene(16.69%),the main component of Magnolia denudata flower aroma oils is germacrene D(27.38%),the main aroma components of the leaf from Magnolia liliiflora is primarily thujene(27.81 %).4 The seed quality of the whole pieces of fruit accounted for 15.41%;the composition and content of fatty acid from nutshell、aril and seed are different from each other;The study found that the nutshell of fruit has a high flavonoid content,thebest method of extracting flavonoids is extraction temperature of 60℃, extraction time of 100 min, extraction liquid ratio of 1:30.Under these conditions,the extract quantity of flavonoids could reach 57.95mg/g.
