Saponins are widely distributed in the plant kingdom and have been shown to be active components of many medicinal herbs. In this study, a two-dimensional purification method based on reversed-phase liquid chromatography coupled with hydrophilic interaction liquid chromatography was successfully applied to purify saponins from leaves of Panax notoginseng. Nine saponin reference standards were u...

Sea cucumbers are prolific producers of a wide range of bioactive compounds. This study aimed to purify and characterize one class of compound, the saponins, from the viscera of the Australian sea cucumber Holothuria lessoni. The saponins were obtained by ethanolic extraction of the viscera and enriched by a liquid-liquid partition process and adsorption column chromatography. A high performanc...

In the present study the adaptogenic activities of the saponin fractions of the leaves and roots of Polyscias fruticosa (L) Harms (Araliaceae) were studied in comparision wit white panax ginseng root saponins. The antibacterial activity of the polyacetylenic compound in leaves were also studied. The adaptogenic activity studies showed that polyscias fruticosa leaf and root saponins have effecti...

The production of low-molecular-weight antimicrobial molecules within plants is one component of defense against pathogens. Among them, preformed antimicrobial compounds (phytoanticipins) are the first biochemical barriers against pathogens. Saponins (a group of phytoanticipins) are present constitutively in plants and play important roles in plant defense. A variety of biological roles have be...

Direct detection of saponins in medicinal plants using Fourier Transform Infrared (FTIR) spectroscopy is reported in this paper. Crude dry plant powders were mixed with potassium bromide (KBr) powder and compressed to a thin pellet for infrared examination. FTIR spectra of the test samples showed -OH, -C=O, C-H, and C=C absorptions characteristic of oleanane triterpenoid saponins. The C-O-C abs...
