Abstract

In this work, we analyze optical characteristics of greater celandine (Chelidonium majus L.) ethanol solution extracts and fresh leaf samples. Optical emission of samples was measured using a pulsed laser excitation of tunable wavelengths (320–470 nm) and time-resolved detection system. Results of our analysis reveal two distinct alkaloid optical emission bands with different excitation characteristics. Chlorophyll fluorescence emission band was also detected. Time-resolved analysis of luminescent spectra shows that lifetimes of both alkaloid fluorescence bands and chlorophyll band are in nanosecond domain

大白屈菜植物提取物 (Chalidonium majus L.) 的时间分辨发光光谱

摘要

在这项工作中，我们分析了白屈菜 ( Chelidonium majus L.) 乙醇溶液提取物和新鲜叶子样品的光学特性。使用可调波长（320-470 nm）的脉冲激光激发和时间分辨检测系统测量样品的光发射。我们的分析结果揭示了具有不同激发特性的两个不同的生物碱光发射带。还检测到叶绿素荧光发射带。发光光谱的时间分辨分析表明，生物碱荧光带和叶绿素带的寿命均在纳秒域内
