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. …

Steroidal saponins and sapogenins from Agapanthus praecox Willd
Agapanthin, C₅₁H₈₄O₂₄, a steroidal saponin, isolated from rhizomes of Agapanthus praecox Willd., yielded, on acid hydrolysis, the steroidal sapogenin agspanthagenin and galactose and rhamnose in the molecular ratio of 3:l. The structure assigned to agapanthagenin has been confirmed oh the basis of …

Effect of Soyasaponin Fractions on Human Colon Cancer Cells
<p>Group B saponins, the predominant form of saponins in heat-treated soy products, have been shown to possess hypocholesterolemic, antimutagenic, and anticarcinogenic properties. Previous studies have evaluated crude mixtures of soyasaponins, but studies evaluating a single purified soyasaponin as …

Ginsenosides, Glycosidases and the Ginseng-Pythium Interaction
Ginsenosides, the triterpenoid saponins produced by American ginseng (Panax quinquefolius L.), have been extensively studied for their medicinal value, however, their function in the rhizosphere remains largely unknown. Like other saponins, ginsenosides possess mild fungitoxic activity toward some …

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 …
