Quantitative Determination of Pigments in Agastache Grass by Spectrophotometry
Abstract
The quantitative determination of the amount of chlorophylls in the grass ofthe Agastache rugosa by spectrophotometrywas carried out. Optimal pigment extraction conditions have been developed to maximize the yield of the target compounds.It has been shown that effective extraction is achieved using 95% ethyl alcohol (raw material:extractant ratio 1:30), a grinding degreeof 1 mm and an extraction timeof 90 minutes. Chlorophyll a has been identified as the dominant pigment (analytical wavelength 664±2 nm). The maximum amountof chlorophylls in the grass of the wrinkled mulberry was 9.30%, which indicates the prospectsof this plant asa source of valuable pigments.
