smilagenin/yucca

The effects of steroidal saponins (SAP) isolated from Yucca schidigera extract on ruminal bacteria and fungi were investigated in pure culture studies. Prevotella bryantii, Ruminobacter amylophilus, Selenomonas ruminantium and Streptococcus bovis were cultured through ten 24-h transfers in ruminal

Fifty-five mg per kg live weight of crystallized Yucca schidigera saponins, corresponding to 26 mg/kg live weight of sapogenins, was given daily intraruminally to two lambs for 11 consecutive days. Neither of the lambs showed any sign of toxicity throughout the experimental period. One lamb was

Ten steroidal saponins with cis-fused A/B ring, including a smilagenin glycoside, elephanoside A (4), and the five furostanol bisdesmosides, elephanosides B-F (6-10), were isolated from the stems of Yucca elephantipes Regel. (Agavaceae). Their structures were determined by detailed chemical and

Spectrophotometrically determined substances in Yucca extract, listed as "Yucca foam extract" in the "List of Existing Food Additives in Japan", were investigated by GC/MS, TLC and GC. A TLC method using an anisaldehyde color developing reagent similar to that employed in spectrophotometry was
