Abstract
The absorption spectra of brunescent cataractous lenses and their homogenates were analyzed under various conditions by using a double wavelength spectrophotometer. The absorption spectra of the samples were in good agreement with those of synthetic xanthommatin derived from 3-hydroxykynurenine. The results provided evidence that brown pigment in the brunescent cataractous lenses is mainly composed of xanthommatin.
摘要
使用双波长分光光度计在各种条件下分析了褐色白内障晶状体及其匀浆的吸收光谱。样品的吸收光谱与由3-羟基犬尿氨酸衍生的合成黄蝶呤的吸收光谱高度一致。结果提供了证据，表明褐色白内障晶状体中的褐色色素主要由黄蝶呤组成。
