Saponin Removal from Quinoa by Abrasion Processing
<p>Quinoa is coated with a thin layer of saponins, glycosylated triterpenoids, that produce a bitter flavor when consumed. The average saponin content in commercial varietals from Bolivia average around 2.7% saponins and organoleptic testing shows the threshold for noticing a bitter flavor is below …

Chemical aspects of saponin bioactivity and ovine photosensitization diseases
A general review of saponin chemistry, bioactivities and of chemical aspects of saponin-associated hepatogenous photosensitization of ruminants (sheep, goats, and cattle) is presented. A field trial was undertaken to explore the genin dose/response hypothesis that saponins produced by the plant …

Toward the Synthesis of CAY-1, an Antifungal Steroidal Saponin
… been emerging. CAY-1 is an antifungal steroidal saponin which was isolated from the fruit of the cayenne pepper plant in 0.1% yield. In Vitro studies of CAY-1 have shown it to be an effective antifungal agent against sixteen pathogenic fungal strains and it showed no cytotoxicity toward mammalian …

Combinatorial biochemistry of triterpene saponins in plants
… to identify candidate genes involved in the saponin biosynthesis of five different plants. After targeted metabolite profiling confirmed the induction of triterpene saponin biosynthesis by methyl jasmonate treatment, a genome-wide cDNA-AFLP transcript profiling was carried out for the five …

EFFECT OF SAPONINS ON LAMB MEAT QUALITY
… of this research was to evaluate the effects of saponins on lamb meat quality. In the first experiment, increasing levels of saponins from Quillaja saponaria L. were supplemented to lambs to evaluate their effects on fatty acid composition and cholesterol content in the muscle longissimus dorsi. …

Defining the role of cellulose synthase-like M genes in the plant cell wall
… C-3 position of triterpenoid aglycones during saponin biosynthesis in plants. However, this has not yet been investigated for tomato (Solanum lycopersicum) saponins, which are steroidal glycoalkaloids (SGA). The work in this thesis has delved more into the role of tomato CslM genes in cell wall …
