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...

BACKGROUND Panax notoginseng is commonly used for the treatment of cardiovascular diseases in China. The present study investigates the effects of three different saponin fractions (ie total saponins, PNS; protopanaxadiol-type saponin, PDS; and protopanaxatriol-type saponin, PTS) and two major individual ingredients (ie ginsenoside Rg1 and Rb1) from P. notoginseng on the endothelial inflammator...

Let f be a transcendental meromorphic function and U be an invariant Baker domain of f . We use estimates for the hyperbolic metric to show that there is a relationship between the size of U and the proximity of f in U to the identity function, and illustrate this by discussing how the dynamics of transcendental entire functions of the following form vary with the parameter a: f(z) = az + bzke−...

A glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) was purified from human serum and used for studies on the release of GPI-anchored Thy-1 glycoprotein from mouse T lymphoma cells Y191. Previous studies have shown that whereas GPI-PLD is highly active against detergent-solubilized GPI-anchored proteins, it is normally unable to release GPI-containing proteins anchored in a lipid ...

Root growth and saponin production in the root culture of Panax ginseng C. A. Meyer were investigated under various pH values, concentrations of sucrose, nitrogen and phosphate and elicitors. The pH of a medium did not have a significant effect on root growth, but apparently affected the saponin content. The maximum saponin content of 0.26 % was obtained at pH 6.0. The optimal concentrations of...

Four new saponins, 3-O-[beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl]-16a lpha-hydroxyoleanolic acid 28-O-beta-D-glucopyranosyl ester (called aralia-saponin I), 3-O-[beta-D-glucopyranosyl(1-->3)-alpha-L-arabinopyranosyl]-16a lpha-hydroxyhederagenin 28-O-beta-D-glucopyranosyl ester (aralia-saponin II), 3-O-[beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranosyl(1-->3)-alpha-L-+ ++arabinopyr...

Background Saponins identified from fenugreek (Trigonella foenum-graecum) seeds are reported effective on dyslipidemia. However, the definite mechanism is still not elucidated systematically. In this study, we evaluate the effects of saponin extract on cholesterol absorption, metabolism, synthesis, and reverse cholesterol transport in vivo. Methods Saponin extract was prepared according to a ...

Tea saponin of functional ingredients extracted from camellia meal, is China's unique natural functional molecules. With silicone oil containing hydrogen and unsaturated polyether silicon hydrogenation reaction, and then esterification with tea saponin, and the tertiary amine hydrochloride reaction of tea saponin was modified organosilicon quaternary ammonium salt and its conversion rate reache...

The rubidium efflux from hypothermic rat hearts perfused by the Langendorff method at 20°C was studied. At this temperature 87Rb-NMR efflux experiments showed the existence of two 87Rb pools: cytoplasmic and mitochondrial. Rat heart mitochondria showed a very slow exchange of mitochondrial Rb+ for cytoplasmic K+. After washout of cytosolic Rb+, mitochondria kept a stable Rb+level for >30 min. R...
