Determination of Eight Organic Acids in Blueberries by HPLC
A high performance liquid chromatography (HPLC) method was established for the simultaneous determination of 8 organic acids in blueberry fruit extract.This method was then used to determine the contents of organic acids in blueberries from 26 cultivars.Among the blueberry cultivars tested,the content of total organic acids (25.135 26 mg/g fresh fruit) was highest in Sierra and lowest in Croaton (only 2.368 31 mg/g fresh fruit).This method is simple,reproducible,accurate,reliable and useful for the analvsis of organic acids in blueberries.
