A permeable cell system has been developed by treatment with saponin for studying in vitro replication of DNA and chromatin. DNA replication of simian virus 40 nucleoprotein complexes (SV40 chromatin) in saponin-treated permeable cells was found to be more efficient than that in digitonin-treated permeable cells. Autoradiography of the agarose-gel revealed that [alpha-32P]dCTP was incorporated ...
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 ...
Saponin permeabilization of tissue slices is increasingly popular for characterizing mitochondrial function largely because it is fast, easy, requires little tissue and leaves much of the cell intact. This technique is well described for mammalian muscle and brain, but not for liver. We sought to evaluate how saponin permeabilization reflects aspects of liver energy metabolism typically assesse...

Trigonella foenum-graecum, commonly called fenugreek, is a leguminous plant native to many Asian, Middle Eastern and European countries. Fenugreek oil is very effective in digestion. Identification of fenugreek genotype rich in saponins and fixed oil will be useful for pharmaceutical industries. In the present study, steroidal saponin and fixed oil content was analysed in 46 diverse fenugreek g...
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...
Background Indian traditional system of medicine uses Pithecellobium dulce for the treatment of diabetes mellitus. Objectives This study aims to develop an extract rich in saponins derived from seeds of the plant and to evaluate its antihyperglycemic potential in vitro and in vivo. Materials and Methods Defatted seeds were extracted with methanol and processed to afford saponin-enriched fra...
Saponins, a group of glycosidic compounds present in several plant species, have aglycone moieties that are formed using triterpenoid or steroidal skeletons. In spite of their importance as antimicrobial compounds and their possible benefits for human health, knowledge of the genetic control of saponin biosynthesis is still poorly understood. In the Medicago genus, the hemolytic activity of sap...
The aim of this study was to determine and compare the preventive effect of Korean White Ginseng and Red Ginseng on oxidative stress in H2O2-treated HepG2 cells. The roots of ginseng were extracted with 70% methanol and partitioned with butanol to obtain saponin fractions, which have been known as bioactive constituents of ginseng. 2',7'-Dichlorofluorescein diacetate (DCF-DA) assay and malondia...
Panax pseudo-ginseng subsp. pseudo-ginseng has a carrot like root with a small rhizome. It was shown that the saponin composition of roots and rhizomes of this subspecies collected in Tibet and China was extremely poor. From the roots and rhizomes collected in Central Nepal, (specimen-PNct), only a small amount of an oleanolic acid saponin, beta-D-glucopyranosyl-oleanolate (2) was isolated toge...
