Ir is often used to investigate the reaction of thermal imine because the groups of amido acid and imide possess characteristic ir spectroscopy and ir method has the merits of simpleness, convenience and speediness
由於紅外光譜法具有簡單、方便、快速等特點，酰胺酸、酰亞胺基團又有著特定的紅外吸收峰，因而成為研究熱亞胺化反應最常用的測試方法。Was added, the absorption of morin at 350nm decreased and a new absorption peak at 419nm appeared. adding of nucleic acids to the morin - al binary system leads to decrease of the absorption at 350nm and great increase at 419nm. there is an isochromatic point at 370nm. the increase of absorbance at 419nm is proportional to the amount of nucleic acids added within certain concentration range. based on this, a new sensitive nucleic acids analysis method is established. the linear ranges of ct dna, fs dna and y rna are 0. 7135. 4 0. 6425. 6 and 0. 9428. 4g ml, respectively
鋁離子的加入使桑色素350nm處的吸收峰下降，在419nm處出現桑色素-鋁絡合物的吸收峰。再往桑色素-鋁離子二元體系中加入核糖核酸或脫氧核糖核酸，則進一步引起桑色素350nm吸收峰的降低， 419nm處的吸收大大加強，同時在370nm處有一等色點。 419nm處吸光度的增加值與加入的核酸量在一定范圍內成正比，基於此建立了在較寬范圍內測定核酸的方法。Methods and results we observed the characteristics and its structure of flos carthami and adulterate flos carthami, calcium salt and sulphate which were checked out in adulterate fins cartharni ' s physical and chemical nature, and 3 different colors of flecks which were checked out in tlc of adulterate flos carthami, by some methods of detection such as identification experiences microstructure, physical and chemical nature, tlc, ash content, absorbency and impurity
方法與結果通過經驗鑒別、顯微組織、理化反應、薄層色譜、灰分、吸光度及雜質等檢測方法，觀察了紅花與摻偽紅花的性狀和組織特徵，理化反應中摻偽紅花檢出鈣鹽和硫酸鹽，薄層色譜中摻偽紅花檢出三個不同顏色的斑點。
