Acid hydrolysis of saponin‐rich extracts of quinoa, lentil, fenugreek and soybean to yield sapogenin‐rich extracts and other bioactive compounds

Abstract

Hydrolysis times of 1 h for saponin-rich extracts from the assayed seeds guarantee the maximum transformation to sapogenin-rich extracts, along with phytosterols and tocopherol. Fenugreek and quinoa seeds are preferred for this. © 2018 Society of Chemical Industry.
