Usage

Uses

Tormentic Acid is isolated from Tormentil rhizomes and has inhibitory effect on carcinognenesis. In addition, Tormentic Acid has been implicated to be a potential therapeutic candidate for the prevention of APAP-induced liver injury by inhibiting oxidative stress and inflammation.

Bioactive Triterpenoids from the Twigs of Chaenomeles sinensis

Chaenomeles sinensis has been consumed traditionally for the treatment of throat diseases, diarrhea, inflammatory diseases, and dry beriberi. Repeated chromatography of the CHCl3-soluble fraction from the 80% MeOH extract of C. sinensis twigs led to the isolation of three new triterpenoids, sinenic acid A (1), 3β-O-cis-feruloyl-2α,19α-dihydroxyurs-12-en-28-oic acid (2), and 3β-O-cis-caffeoylbetulin (3), together with 20 analogues. The chemical structures of 1-3 were determined using diverse NMR techniques and HRMS data analysis, chemical methods, and computational approaches supported by advanced statistics (CP3). All the purified compounds were evaluated not only for their cytotoxicity against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and HCT-15) but for their potential neuroprotective effects through induction of nerve growth factor in C6 glioma cells. Their anti-inflammatory effects were also assessed by measuring nitric oxide levels in lipopolysaccharide-insulted murine microglia BV2 cells.

Hepatoprotective triterpenes from traditional Tibetan medicine Potentilla anserina

A methanol extract from the tuberous roots of Potentilla anserina (Rosaceae) exhibited hepatoprotective effects against d-galactosamine (d-GalN)/lipopolysaccharide-induced liver injuries in mice. Six triterpene 28-O-monoglucopyranosyl esters, potentillanosides A-F, were isolated from the extract along with 32 known compounds, including 15 triterpenes. The structures of potentillanosides A-F were determined on the basis of spectroscopic properties and chemical evidence. Four ursane-type triterpene 28-O-monoglycosyl esters, potentillanoside A (IC50 = 46.7 μM), 28-O-β-d- glucopyranosyl pomolic acid (IC50 = 9.5 μM), rosamutin (IC 50 = 35.5 μM), and kaji-ichigoside F1 (IC50 = 14.1 μM), inhibited d-GalN-induced cytotoxicity in primary cultured mouse hepatocytes. Among these four triterpenes, potentillanoside A, rosamutin, and kaji-ichigoside F1 exhibited in vivo hepatoprotective effects at doses of 50-100 mg/kg, p.o. The mode of action was ascribable to the reduction in cytotoxicity caused by d-GalN.
