To analyze our beer samples for resveratrol content, be will be using '''H'''igh '''P'''erformance '''L'''iquid '''C'''hromatography (HPLC), which will allow us to separate the metabolites produced by the yeast and analyze these compounds by spectrophotometry. By comparing HPLC chromatogram peaks of metabolites produced by our yeast with a resveratrol-only standard, we can identify if resveratrol is being produced, and at what quantities. Below, we show our initial data for HPLC calibration curves using known quantities of resveratrol and p-coumaric acid standards and test chromatograms using extracts from different wine samples. | To analyze our beer samples for resveratrol content, be will be using '''H'''igh '''P'''erformance '''L'''iquid '''C'''hromatography (HPLC), which will allow us to separate the metabolites produced by the yeast and analyze these compounds by spectrophotometry.
