sea cucumbers saponins are triterpenoid glycosides which exert beneficial biomedical effects. this study was performed to assess the effect of saponin extracted from sea cucumber holothuria leucospilota            ( h. leucospilota ) on maturation of mice oocytes and granulosa cells. the germinal vesicles oocytes were collected from 6–8 weeks old naval medical research institute (nmri) mice ova...

OBJECTIVE In the present study, the antiviral effects of polyphylla saponin I isolated from Parispolyphylla on influenza A virus are investigated both in vitro and in vivo. METHODS Column chromatography and reversed phase liquid chromatography separation technology were used to extract and purify polyphylla saponin I. The purity of polyphylla saponin I was assayed by high performance liquid c...

Saponins have been considered as promising natural substances for mitigating methane emissions from ruminants. However, studies reported that addition of saponin-rich sources often arrived at contrasting results, i.e. either it decreased methane or it did not. The aim of the present study was to assess ruminal methane emissions through a meta-analytical approach of integrating related studies f...

The moon jellyfish (Aurelia sp.1) is thought to be a nuisance for the sea cucumber aquaculture, which commonly occur in the sea cucumber (Apostichopus japonicus) culture ponds of the Yellow Sea, China. To develop an appropriate method to control Aurelia sp.1 blooms, the toxic effects of tea saponin on Aurelia sp.1 ephyrae and polyps were tested in laboratory experiments. Our results revealed th...

The effects of powdered Fagonia cretica plant and its two major triterpenoid saponins (saponin-I and saponin-II) on various blood endocrinological parameters. Prolactin namely, serum prolactin, serum thyrotropin, serum thyroxine and serum cortisol of normal male rabbits were investigated. Two major triterpenoid compounds, saponin-I and saponin-II, were isolated from its ethanolic extract by rep...

Focusing on a functional component of Momordica charantia, saponin, we investigated its effects on serum glucose and neutral fat levels. Saponin was extracted as a butanol-soluble fraction (saponin fraction) from hot blast-dried Momordica charantia powder. The disaccharidase-inhibitory activity and the pancreatic lipase-inhibitory activity of the saponin fraction were measured, and in vivo suga...

Glucose uptake by isolated diaphragms of both diabetic, following streptozotocin administration, and non-diabetic animals increased in presence of an oleanane-type triterpenoid saponin isolated from the roots of M. cymbalaria. Insulin release was augmented by the presence of the saponin of M. cymbalaria (1 mg/mL) in rat insulinoma cell line (RIN-5F) preexposed to adrenaline (5 microM) and nifed...

Nanoparticulate platinum (II) (nano Pt) is a powerful antioxidant that is widely used to scavenge reactive oxygen species (ROS). The antioxidant activity of nano Pt has gained attention as a potentially useful therapeutic for a variety of diseases including cancer and aging. In the present study, we prepared nanoparticulate saponin-Pt (II) (nano saponin-Pt) conjugates using the ethanol reductio...

This study was conducted to elucidate the mechanism underlying the hypolipidemic action of karaya saponin or Rhodobacter (R.) capsulatus. A total of 40 laying hens (20-week-old) were assigned into four dietary treatment groups and fed a basal diet (as a control) or basal diets supplemented with either karaya saponin, R. capsulatus, or both for 60 days. The level of serum low-density-lipoprotein...
