Description
Technical field
The invention belongs to constituent content determination techniques field, be specifically related to a kind of method of naringenin and eriodictyol content in Simultaneously test fresh-cut water chestnut yellow tissue.
Background technology
Water chestnut (Eleocharistuberosa), another name water chestnut, an ancient name for water chestnut, Di Li, black taro etc. are the underground bulb that per nnial herb Cyperaceae Eleocharis is formed.The water chestnut not only crisp succulence of matter, nutritious, but also can be used as medicine, various diseases is had to the effect of supplemental treatment.Have the good reputation of " underground snow pear " since ancient times, northerner regards it as " south of the River ginseng ".But water chestnut is after fresh-cut process, cutting surfaces can turn yellow in a short time, has had a strong impact on exterior quality and other value.Early-stage Study finds, causes the main cause of yellow to be that in Fresh-cut Chinese Water-chestnut, Cucumber generates caused by Flavonoid substances through phenylpropyl alcohol alkane metabolic pathway, along with the intensification of yellow, and the corresponding increase of the content of general flavone in fresh-cut water chestnut.Carry out separation and purification and Structural Identification further by yellowed matter, show that the yellow of fresh-cut water chestnut cutting surfaces may be main relevant with naringenin two kinds of Flavonoid substances with eriodictyol.Therefore, set up one can in Simultaneously test fresh-cut water chestnut yellow tissue eriodictyol and naringenin content significant to research fresh-cut water chestnut xanthating machine fixture.
In recent years, have both at home and abroad and detect and the independent bibliographical information of assay about naringenin, eriodictyol, mainly high performance liquid chromatography (HPLC), or with additive method coupling, but HPLC method mainly concentrates on naringenin in Chinese herbal medicine, eriodictyol detects and the mensuration of content, and these conditions might not be applicable to naringenin in fresh-cut water chestnut yellow tissue and eriodictyol detection and assay thereof.In addition, also there is not yet the report that HPLC method measures naringenin or eriodictyol in fresh-cut water chestnut yellow tissue at present, more do not had the report of naringenin and eriodictyol in Simultaneously test fresh-cut water chestnut yellow tissue.
Summary of the invention
