| Description: |
Bellidifolin has anti-oxidation, hepatoprotective, anti-inflammatory and antitumor actions, it may contribute to the protective effects associated with nerve injury initiated by hypoxia by mechanisms related to inhibition of cell apoptosis independent of the ERK pathway. Bellidifolin shows interesting inhibitory activity of monoamine oxidases (MAO) A, it could be useful for treating type-2 diabetes, likely via the improvement of insulin resistance (IR).
Bellidifolin also shows an antifungal effect (MIC values of 50 microg/mL). |

(Gentianaceae) is more commonly known as "Ganyan-cao" and used mainly as a traditional Chinese folk medicine for the treatment of acute bilious hepatitis, cholecystitis, fever, intoxification and jaundice.
METHODS AND RESULTS:
The active hepatoprotective constituents of Swertia punicea were purified using various column chromatography techniques. The structures of two isolated compounds were determined on the basis of spectroscopic data interpretation such as NMR analysis. The hepatoprotective activities of isolated compounds were evaluated by using hepatotoxicity in vitro and dimethylnitrosamine-induced rat hepatic fibrosis in vivo, respectively.
Two xanthones, 1, 7-dihydroxy-3, 4, 8-trimethoxyxanthone (1) and Bellidifolin (2) were isolated from the stems of Swertia punicea. The compounds 1 and 2 exhibited notable hepatoprotective activities against carbon tetrachloride (CCl4) -induced HepG2 cell damage, and effectively alleviated the levels of aspartate transaminase (AST), lactate dehydrogenase (LDH), superoxide dismutase (SOD) and malonic dialdehyde (MDA) induced by CCl₄ in a concentration-dependent manner. Co-treatment with compound 2 significantly increased the cell viability compared with N-acetyl-p-aminophenol (APAP) treatment. Compound 2 also alleviated APAP-induced hepatotoxicity by increasing glutathione (GSH) content and decreasing hydroxyl free radical (·OH) levels and reactive oxygen specises (ROS) production. In addition, the protective effect of compound 1 significantly alleviated DMN-induced liver inflammation and fibrosis. Oral administration of compound 1 recovered the reduction of albumin (ALB) and reversed the elevation of serum alanine transaminase (ALT), AST and total bilirubin (TBIL) in dimethylnitrosamine (DMN)-induced fibrotic rats. Severe oxidative stress induced in fibrotic rats was evidenced by a 1.5-fold elevation in MDA and a fall in the SOD activity, and treatment with compound 1 protected against these adverse effects. Recovery of rat liver tissue against DMN-induced hepatocellular necrosis, inflammatory changes and hepatic fibrosis by compound 1 is also confirmed by H&E and Masson stained histopathological evaluation of liver tissue.
CONCLUSIONS:
Two xanthones from Swertia punicea exhibited hepatoprotective activities in vitro (compounds 1 and 2) and in vivo (compound 1), respectively. | | Z Naturforsch C. 2012 Jan-Feb;67(1-2):29-38. | | Antimicrobial and antioxidant activities of Gentianella multicaulis collected on the Andean Slopes of San Juan Province, Argentina.[Pubmed: 22486039] | The infusion of the aerial parts of Gentianella multicaulis (Gillies ex Griseb.) Fabris (Gentianaceae), locally known as 'nencia', is used in San Juan Province, Argentina, as stomachic and as a bitter tonic against digestive and liver problems.
METHODS AND RESULTS:
The bioassay-guided isolation of G. multicaulis extracts and structural elucidation of the main compounds responsible for the antifungal and free radical scavenging activities were performed. The extracts had strong free radical scavenging effects in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay (45-93% at 10 microg/mL) and ferric-reducing antioxidant power (FRAP) assay at 200 microg/mL. DemethylBellidifolin (4) had high antioxidant activity in the DPPH and FRAP assay. The dermatophytes Microsporum gypseum, Trichophyton mentagrophytes, and T. rubrum were moderately inhibited by the different extracts (MIC values of 125-250 microg/mL). DemethylBellidifolin (4), Bellidifolin (5), and isoBellidifolin (6) showed an antifungal effect (MIC values of 50 microg/mL), while swerchirin (3) was less active with a MIC value of 100 microg/mL. In addition, oleanolic acid (1) and ursolic acid (2) were also isolated.
CONCLUSIONS:
These findings demonstrate that Gentianella multicaulis collected in the mountains of the Province of San Juan, Argentina, is an important source of compounds with antifungal and antioxidant activities. |

| Phytomedicine. 2010 Jun;17(7):533-9. | | Anti-diabetic effect of methylswertianin and bellidifolin from Swertia punicea Hemsl. and its potential mechanism.[Pubmed: 19962285 ] |
METHODS AND RESULTS:
In this study, we continued to investigate the hypoglycemic activity of Swertia punicea Helmsl., the hypoglycemic and hypolipidemic effects of methylswertianin and Bellidifolin from the active ethyl acetate (EtOAc) fraction, and the potential mechanism(s) underlying the improvement of insulin resistance.
Streptozotocin (STZ)-induced type 2 diabetic male BABL/c mice treated with methylswertianin and Bellidifolin at different doses (orally, 200 and 100mg/kg body wt./day) for 4 weeks were analyzed in comparison to untreated mice. The results proved that methylswertianin and Bellidifolin significantly reduced fasting blood glucose (FBG). The administration of both compounds also improved the oral glucose tolerance and lowered fasting serum insulin (FINS). Moreover, post-administration evaluation revealed lower serum total cholesterol (TC), low density lipoprotein cholesterol (LDL) and triglyceride (TG) levels and increased relative high density lipoprotein cholesterol (HDL) concentrations (HDL/TC). Methylswertianin and Bellidifolin appeared to improve insulin resistance by enhancing insulin signaling. The expression levels of insulin-receptor alpha subunit (InsR-alpha), insulin-receptor substrate-1 (IRS-1), and phosphatidylinositol 3-kinase (PI3K) were also increased after administration. Meanwhile, methylswertianin and Bellidifolin increased hepatic glycogen content, decreased glucokinase (GK) activities and increased glucose-6-phosphatase (G6Pase) activities.
CONCLUSIONS:
In conclusion, these result indicated that methylswertianin and Bellidifolin could be useful for treating type-2 diabetes, likely via the improvement of insulin resistance (IR). |
