来自近期英语论文中的用乙醇测定植物叶片光合色素含量的方法

One method for determining the photosynthetic pigment content of plant leaves in recent English literature involves the use of ethanol. This method involves grinding the leaf tissue in ethanol to extract the pigments, followed by spectrophotometric analysis to measure the absorbance of the pigments at specific wavelengths. The pigment content can then be calculated using standard equations based on the absorbance values. This method is considered to be a reliable and accurate way to determine photosynthetic pigment content in plant leaves
