Seventeen-day-old Nile tilapia fry were fed a standard diet (C) or diets containing 50-700 mg kg(-1) Quillaja saponin (QS) extract (groups S50, S150, S300, S500 and S700). After the first 8 weeks, 30 randomly selected tilapia from each of the treatments were placed in separate aquaria and fed the standard diet without saponins from then on (these were designated S50/C, S150/C, S300/C, S500/C an...

There is growing interest in development of natural products as anti-cancer and chemopreventive agents. Many triterpenoids have been proved as potential agents for chemoprevention and therapy of breast cancer. Ginsenosides from ginseng, which mostly belong to dammarane-type triterpenoids, have gained great attention for their anti-breast cancer activity with diverse mechanisms. However, studies...

The chemical action of photodynamic substances is very wide. Not only do they cause alteration of the labile molecules of ferments and toxins, bu t they are definite and even intense protoplasmic poisons. Their action is, however, not limited to the complex structures and molecules of these bodies, bu t is capable of being exerted upon much simpler and, chemically speaking, more definite substa...

background: malignant melanoma is a highly aggressive malignant melanocytic neoplasm which resists against the most conventional therapies. sea cucumber as one of marine organisms contains bioactive compounds such as polysaccharide, terpenoid and other metabolites which have anti-cancer, anti-tumor, anti-inflammatory and antioxidant properties. the present study was designed to investigate the ...

The present study monitored the effect of 2, 10, and 50 mg/L of Panax notoginseng saponin exposure following hypoxia-reoxygenation injury in fetal rat cortical neurons. Results showed that varying doses of Panax notoginseng saponin significantly enhanced the cell viability of neurons, reduced malondialdehyde content, increased superoxide dismutase activity, inhibited mRNA and protein expression...

Saponin-rich GM extract was prepared by refluxing 25 g of GM with 250 ml of EtOH/H2O (1:1, v/v) for 3 h then filtering and distilling EtOH at 50 C. The refluxed extract was partitioned with equal volume of BuOH obtaining crude saponin-rich GM extract with 4.8 ± 0.6% DM of GM that was purified by RP-HPLC eluting 20%, 60% and 100% MeOH fractions with 2.04 ± 0.32%, 0.91 ± 0.16% and 1.55 ± 0.15% DM...

The genus Allium is a rich source of steroidal saponins, and its medicinal properties have been attributed to these bioactive compounds. The saponin compounds with diverse structures play a pivotal role in Allium's defense mechanism. Despite numerous studies on the occurrence and chemical structure of steroidal saponins, their biosynthetic pathway in Allium species is poorly understood. The mon...

Saponins are used in medicine due to their pharmacological and immunological effects. To better understand interactions of saponins with model membranes and natural membranes of, for example, erythrocytes, Langmuir film balance experiments are well established. For most saponins, a strong interaction with cholesterol was demonstrated in dependence of both the aglycone part and the sugar moietie...

Etioplast, Protochlorophyllide, Prolamellar Body, Saponin, Red Light Exposure to red light of high intensities leads to saponin and prolamellar body degradation in etiolated Avena sativa seedlings. Exposure to red light of low intensities increases the saponin percentage found in prolamellar bodies without changing the overall saponin content. Proto­ chlorophyllide is assumed to act a decisive ...

AIM This investigation aimed to assess the hepatoprotective effect of saponin fraction isolated from the fruit pericarp of Sapindus mukorossi on carbon tetrachloride (CCl(4))-induced hepatotoxicity. METHODS Fruit of S. mukorossi was collected and authenticated, and dried pericarp powder subjected to extraction with cold ethanol (70%) by maceration followed by isolation of total saponin fracti...
