一般描述
叶绿素 b 属于与镁结合的卟啉类。它主要吸收蓝色区域的光能，并与叶绿素 a 一起作用，呈现植物和绿藻的绿色。
应用
本分析标准品还可作如下用途：
- 基于傅立叶变换红外（FTIR）光谱定量分析五个个品牌绿茶样品中的叶绿素（a & b）和脱镁叶绿素（a & b）
- 建立高效液相色谱-二极管阵列检测-质谱（HPLC-DAD-MS），用于分离和测定蒲公英样品中的叶绿素及其衍生物
- 在高效薄层色谱（HPTLC）分离后通过紫外-可见分光光度法对 14 份膳食补充剂样品中的叶绿素、降解产物、类胡萝卜素和叶绿素进行定量分析
- 评估压力、温度、CO2 流速和极性助溶剂对用于食品加工的微藻中类胡萝卜素和叶绿素超临界萃取（SFE）的影响
- 通过两种紫外-可见分光光度法同时测量草莓、杏和覆盆子果实样品中的叶绿素（a & b）和类胡萝卜素（β-胡萝卜素和番茄红素）

Understanding the conditions affecting cyanobacterial biofilm development is crucial to develop new antibiofouling strategies and decrease the economic and environmental impact of biofilms in marine settings. In this study, we investigated the relative importance of shear forces and surface hydrophobicity
