Saponinum album (SAP) is a complex mixture of triterpene saponins from Gypsophila paniculata L. Although most of the saponins from SAP are characterized, the separation of pure saponins remains time consuming and costly, involving different chromatographic techniques. Recently it was shown that SAP

Gypsogenin (L(1); 3-hydroxy-23-oxoolean-12-en-28-oic acid), a natural saponin, was isolated from the boiling water extract of Gypsophila arrostii roots. In addition, the derivatives gypsogenin thiosemicarbazone (L(2); 23-[(aminocarbonothioyl)hydrazono]-3-hydroxolean-12-en-28-oic acid) and gypsogenin

Alcohol abuse is one of the major causes of liver fibrosis, which shows a sharply increasing trend worldwide, yet effective therapeutic options for advanced alcohol fibrosis are limited. Recently we investigated the effect of anti-fibrosis by isoorientin-2″-O-α-L-arabinopyranosyl (IOA) isolated from

BACKGROUND Gypsophila trichotoma Wend. (Caryophyllaceae) is a medicinal plant which is protected in Bulgaria by the Biodiversity Law. Previous studies have showed the presence of triterpene saponins, sterols, flavonoids, triterpens, etc. OBJECTIVE Gypsogenic acid, isolated from Gypsophila trichotoma
