The aim of the present work was to examine the immunopharmacological (anti-microbial and anti-inflammatory) effect of saponin on human peripheral blood mononuclear cells (PBMC) that are isolated as well as purified from infected (virally) and non-infected (normal) human whole blood samples. However, there is little information available concerning the effect of crude saponin on human PBMC in ca...

A total of 3 experiments (Exp), in vitro and in vivo, were conducted to investigate the effects of saponin extracts from Quillaja saponaria (QS), Yucca schidigera (YS) and Camellia sinensis (TS) on CH4 emissions from steers. The in vitro Exp was carried out to determine the effects of saponin inclusion on ruminal methanogenesis and fermentation parameters. Two doses (0.5% and 2.0% of substrate ...

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...

Ophiocoma erinaceus Muller &Troschel (Ophiocomidae) is part of the extensive group of echinoderm that contains bioactive metabolites. As, the anti cancer potential of brittle star saponin has not been reported against cervical cancer, the present study was conducted to evaluate the anticancer effect of extracted crude saponin. Saponin extraction was conducted using conventional method such as f...

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...

A spectrophotometric method was developed for the determination of saponin in Yucca extract or its preparation for food additive use. A saponin fraction of Yucca extract was prepared by column chromatography with porous polymer, and hydrolyzed with a 2 mol/L mixture of hydrochloric acid-ethanol (1 + 1) to generate sapogenin. Sapogenin amounts were determined by measuring absorbance at 430 nm, b...

Dietary karaya saponin and Rhodobacter capsulatus (R. capsulatus) are known to have hypocholesterolemic actions, as reported in our previous studies. This study examined possible synergistic hypocholesterolemic effects of karaya saponin and R. capsulatus in broilers. A total of 150 broilers were allocated into 10 treatments: control, saponin 25 mg, saponin 50 mg, saponin 75 mg, saponin 25 mg+R....

The present study indicates the efficacy of the saponins fraction of the fruit mesocarp extract of Balanites aegyptiaca Del. (Zygophyllace) as a larvicidal agent against the common dengue vector – Aedes aegypti mosquito. A series of concentrations of fruit mesocarp extract of B. aegyptiaca fruit, its crude saponin extract and pure saponin fraction were tested against the laboratory-reared third...

The present paper focused on antioxidant and cytotoxicity assessment of crude and total saponin fraction of Chlorophytum borivilianum as an important medicinal plant. In this study, three different antioxidant activities (2,2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH), ferrous ion chelating (FIC), and β -carotene bleaching (BCB) activity) of crude extract and total saponin fraction of ...

Vaccination is the main strategy for preventing influenza infection. However, vaccine efficacy is influenced by several factors, including age and health status. The efficacy of the influenza vaccine is much lower (17% to 53%) in individuals over 65 yr of age compared with young adults (70% to 90%). Therefore, increasing vaccine efficacy remains a challenge for the influenza vaccine field. In t...
