The n-butanol extract of the leaves Polyscias fruticosa  (L) Harms (Araliaceae) was tested for its anti-inflammatory activity plethismometrically in egg white induced paw oedema in rats, antipyretic activity and analgesic activity by writhing method phenyl butazone, paracetamol and aspirin were used as positive controls for anti-inflammatory, antipyretic and analgesic activity screening studies...

Certain saponins are bioactive compounds with anticancer, antivirus and antioxidant activities. This paper discussed inhibitory effects of saponins from Xanthoceras Sorbifolia on tyrosinase, through the research of the rate of tyrosinase catalyzed L-DOPA oxidation. The inhibition rate of tyrosinase activity presented non-linear changes with the saponins concentration. The rate reached 52.0% whe...

Etioplasts, Prolamellar Bodies, Saponins, Chromatography Prolamellar body tubules in etioplasts are composed mainly of two saponins. The determination of these saponins in leaves, etioplasts or subfractions of etioplasts is re­ commended to evaluate the concentration of these tubules in a given fraction. Using a densitometer after TLC-separation of the saponins measurements are carried out in a...

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...

A new dolabellane diterpene glycoside, named squoside A, and three new cycloartane glycosides, named squarrosides V, VI, and VII, have been isolated from the dried aerial parts of Thalictrum squarrosum (Ranunculaceae). Their structures were determined by two dimensional (2D) NMR spectroscopic analysis and chemical evidence.

shrub widely distributed throughout China. The anomalous fruits of G. sinensis (AFGS) have long been known in traditional Chinese medicine as a saponin-rich herbal medicine for treating various diseases, such as apoplexy, headache, productive cough, asthma and scabies. In previous studies, we demonstrated that the 70% ethanol extract of AFGS attenuated immunoglobulin E (IgE)-mediated immediate ...
