Cytotoxic spirostane-type saponins from the roots of Chlorophytum borivilianum.
Four new spirostane-type saponins named borivilianosides E-H (1-4) were isolated from an ethanol extract of the roots of Chlorophytum borivilianum together with two known steroid saponins (5 and 6).Expand
Cytotoxic acacic acid glycosides from the roots of Albizia coriaria.
TLDR
Two new oleanane-type saponins, coriariosides A and B, along with a known saponin, gummiferaoside C (3), were isolated from the roots of Albizia coriaria by extensive analysis of 1D and 2D NMR experiments and mass spectrometry. Expand
Three new triterpene saponins from two species of Carpolobia.
Three new acetylated triterpene saponins 1-3 were isolated from the roots of Carpolobia alba and C. lutea. Their structures were established mainly by 2D NMR techniques asExpand
Structure and cytotoxicity of steroidal glycosides from Allium schoenoprasum.
A phytochemical analysis of the whole plant of Allium schoenoprasum, has led to the isolation of four spirostane-type glycosides (1-4), and four known steroidal saponins. Their structures wereExpand
Two new triterpene saponins from Eryngium campestre.
TLDR
Two new triterpene saponins were isolated from the roots of Eryngium campestre (Apiaceae) and their structures were established mainly by 2D NMR techniques and mass spectrometry. Expand
Oleanolic acid and hederagenin glycosides from Weigela stelzneri.
TLDR
The majority of the isolated compounds were evaluated for their cytotoxicity against two tumor cell lines (SW480 and EMT-6), and for their anti-inflammatory activity, and 28-O-β-D-glucopyranosyl exhibited the strongest cytot toxicity on both cancer cell lines. Expand
New triterpenoid estersaponins from the root barks of Pittosporum verticillatum subsp. verticillatum and evaluation of cytotoxicities.
The phytochemical investigation of the root barks of Pittosporum verticillatum Bojer subsp. verticillatum led to the isolation of three new triterpene saponins,Expand
The Dioscorea genus: a review of bioactive steroid saponins
This review will summarize some of the important reports on the chemistry and the biological activities of Dioscorea steroid saponins from the literature data of recent years (2000–2006) and from theExpand
Antifungal steroid saponins from Dioscorea cayenensis.
TLDR
Compound 2 exhibited antifungal activity against the human pathogenic yeasts Candida albicans, C. glabrata and C. tropicalis (MICs of 12.5, 12. 5 and 25 micro g/mL, respectively) whereas 3 showed weak activity and 1 was inactive. Expand
Antiplasmodial activity of aspidosperma indole alkaloids.
TLDR
The antiplasmodial activity of twelve alkaloid with an aspidospermane skeleton was estimated in vitro on chloroquine-resistant and sensitive strains of Plasmodium falciparum and the cytotoxicity and the selectivity index of some alkaloids were also estimated. Expand
