quillaic acid/gypsophila

Two new triterpenoid saponins (1, 2) were isolated from the roots of Gypsophila altissima L. (Caryophyllaceae), together with a known compound (3). The structures of new saponins were established as quillaic acid 3-O-beta-D-xylopyranosyl-(1-->3)-beta-D-glucuronopyranoside (1), and

A cytotoxic triterpenoid saponin was isolated from the under-ground parts of Gypsophila pilulifera Boiss.& Heldr. (Caryophyllaceae) naturally grow in the southwestern region of the Turkey. The structures of saponin was elucidated as

Glucuronide Oleanane-type Triterpenoid Carboxylic Acid 3, 28-Bidesmosides (GOTCAB) saponins are bioactive natural compounds spread in Caryophyllidae. The high complexity of GOTCAB occurring as closely related isobaric and positional isomers is a challenge in their separation and identification. A

Three new triterpenoid saponins were isolated from the roots of Gypsophila oldhamiana. Their structures were elucidated, using a combination of homonuclear and heteronuclear 2D nmr and fabms, as 3-0-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranolyl-(1-->3)] -beta-D-glucuronopyranosyl quillaic

Two new triterpenoids (1-2) were isolated and elucidated from the roots of Gypsophila oldhamiana, together with four known triterpenoids (3-6). Their structures were identified to be 3β-hydroxyolean-13(18)-ene-23, 28-dioic acid (1), 3β, 12α-dihydroxy-23-carboxyolean-28, 13β-olide (2), 3β,

A new saponin, gypoldoside A (1), was isolated from the roots of Gypsophila oldhamiana. On the basis of in-depth NMR-spectroscopic and mass-spectrometric analysis, in combination with chemical evidence, its structure was established as

Two new monodesmosidic triterpene saponins were isolated from the roots of Gypsophila oldhamiana (Caryophyllaceae). Their structures were elucidated on the basis of spectral data to be quillaic acid,

Three new triterpenoid saponins, gypsosaponins A-C (1-3), were isolated from the roots of Gypsophila oldhamiana (Caryophyllaceae). Their structures were established as 3-O-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-beta-D-glucuronopyranosyl quillaic acid

Four new triterpenoid saponins were isolated from the roots of Gypsophila paniculata and G. arrostii. Their structures were elucidated using a combination of homo- and heteronuclear 2D NMR techniques, without having recourse to chemical degradation or modification. The saponins investigated are:

Three new sulfated triterpenoids (1-3), along with one known compound (4), were isolated from the roots of Gypsophila pacifica Kom. The structures of the new compounds were established as 3β-O-sulfate gypsogenin 28-O-β-d-glucopyranosyl ester (1), 3β-O-sulfate gypsogenin (2), and 3β-O-sulfate

A bioassay-guided phytochemical analysis of the triterpene saponins from under ground parts of Gypsophila arrostii var. nebulosa allowed the isolation of two triterpene saponins; nebuloside A, B based on gypsogenin and quillaic acid aglycone. Two new oleanane type triterpenoid saponins (nebuloside

BACKGROUND Saponins have been reported to possess antitumor properties, to inhibit angiogenesis and to induce tumor apoptosis. OBJECTIVE To test the possible cytotoxic effect of crude extracts from four Caryophyllaceae species including Gypsophila paniculata L., Gypsophila trichotoma Wend.,
