smilagenin/キンコウカ属

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

Toxic substances in Narthecium asiaticum Maxim. were isolated and purified, monitoring the oral toxicity in guinea pigs. The crude extract prepared from the methanolic extract of the plant contained 2 major saponins (C8 and C9), and 7 corresponding saponins (C1-7) on TLC. The crude extract was

A sheep was dosed three times per day over six consecutive days with 70 g Narthecium ossifragum, and once on the seventh day with 70 g N. ossifragum. Additionally, it was dosed once on days 1-7 with 20 mg of [20,23,23-2H3]sarsasapogenin. After 7 days, the sheep was killed and GC-MS analysis of the

One sheep was dosed over 4 consecutive days with 2.1 kg of leaves and flower stems of Narthecium ossifragum before it was killed. Sarsasapogenin and smilagenin glycosides, in the ratio 9:1, were the dominant saponins present in the dosed plant material. GC-MS analyses of the free and conjugated
