What is Optimal Solvent Extraction for Mashua Antioxidants about?

This document summarizes research on extracting and purifying phenolic compounds from mashua tubers. It finds that: 1) Acidified solvent mixtures extracted more phenolic compounds than non-acidified solvents. The best mixture was methanol/acetone/water. 2) Purifying crude extracts using solid phase extraction yielded a phenolic fraction and a non-phenolic fraction. The phenolic fraction had much higher levels of total phenolics and antioxidant activity. 3) HPLC analysis showed both genotypes contained
