Stable, Convenient-working Extractants for the Determination of L-ascorbic Acid in Citrus Extracts

, 1996
As an effort to find a more stable, convenient-working extractant than regularly used methaphosphoric acid for determination of L-ascorbic acid (AA) in citrus extracts, several extractants for assay of AA were examined. The extractants tested were (I) 15
