| In vitro | The xanthones gentiacaulein and gentiakochianin are responsible for the vasodilator action of the roots of Gentiana kochiana.[Pubmed: 14531031]Planta Med. 2003 Aug;69(8):770-2.
Gentiana kochiana Perr. et Song. (Gentianaceae), a plant used in the traditional medicine of Tuscany (Italy) as antihypertensive remedy, exerts a vasodilator action on in vitro aortic rings that is probably linked to the blocking of the ryanodine-sensitive Ca++ channels.

Xanthones from Swertia punctata.[Pubmed:12377236]
Phytochemistry. 2002 Oct;61(4):415-20.
Isolation of 1-O-primeverosyl-3,8-dihydroxy-5-methoxyxanthone and 1-O-gentiobiosyl-3,7-dimethoxy-8-hydroxyxanthone, along with five known xanthones, isobellidifolin, methylbellidifolin, isoswertianin, Methylswertianin and norswertianin-1-O-beta-D-glucoside, from the roots of Swertia punctata is reported. In the aerial parts four xanthones, bellidifolin, methylbellidifolin, swertianolin and mangiferin, and flavone-C-glucoside, isoorientin were identified. The chemotaxonomic and pharmacological significance of these results is discussed.
Nonprenylated Xanthones from Gentiana lutea, Frasera caroliniensis, and Centaurium erythraea as Novel Inhibitors of Vascular Smooth Muscle Cell Proliferation.[Pubmed:26580586]
Molecules. 2015 Nov 13;20(11):20381-90.
Aberrant proliferation of vascular smooth muscle cells (VSMC) plays a major role in restenosis, the pathological renarrowing of the blood vessel lumen after surgical treatment of stenosis. Since available anti-proliferative pharmaceuticals produce unfavorable side effects, there is high demand for the identification of novel VSMC proliferation inhibitors. A natural product screening approach using a resazurin conversion assay enabled the identification of gentisin (1) from Gentiana lutea as a novel inhibitor of VSMC proliferation with an IC50 value of 7.84 microM. Aiming to identify further anti-proliferative compounds, 13 additional nonprenylated xanthones, isolated from different plant species, were also tested. While some compounds showed no or moderate activity at 30 microM, 1-hydroxy-2,3,4,5-tetramethoxyxanthone (4), swerchirin (6), and Methylswertianin (7) showed IC50 values between 10.2 and 12.5 microM. The anti-proliferative effect of 1, 4, 6, and 7 was confirmed by the quantification of DNA synthesis (BrdU incorporation) in VSMC. Cell death quantification (determined by LDH release in the culture medium) revealed that the compounds are not cytotoxic in the investigated concentration range. In conclusion, nonprenylated xanthones are identified as novel, non-toxic VSMC proliferation inhibitors, which might contribute to the development of new therapeutic applications to combat restenosis.
Anti-inflammatory activity of compounds isolated from Swertia mussotii.[Pubmed:29117731]
Nat Prod Res. 2017 Nov 9:1-4.
Six compounds were isolated from an ethanol extract of Swertia mussotii and identified as 2-phenylethyl-beta-D-glucoside (1), amaroswerin (2), 1,3,7,8-tetrahydroxyxanthone (3), swertiamarine (4), 1,3,8-trihydroxy-5-methoxyxanthone (5) and Methylswertianin (6). Compounds 1, 2 and 6 were isolated from S. mussotii for the first time. The anti-inflammatory activities of the compounds were evaluated by determining their effect on the production of NO by LPS-stimulated RAW264.7 cells. Amaroswerin was the most potent inhibitor of NO release, with an IC50 value of 5.42 mug/mL. Treatment with amaroswerin inhibited expression of iNOS at both protein and mRNA levels. Amaroswerin also dose-dependently suppressed production of TNF-alpha, IL-6 and IL-1beta and reduced expression of mRNA for these LPS-stimulated pro-inflammatory mediators. Amaroswerin thus inhibits the expression of iNOS, TNF-alpha, IL-6 and IL-1beta by downregulating transcription in LPS-induced RAW264.7 macrophage cells, indicating that amaroswerin may be a valuable therapeutic agent for the treatment of inflammatory diseases.
[Chemical constituents from petroleum ether fraction of Swertia chirayita and their activities in vitro].[Pubmed:29235293]
Zhongguo Zhong Yao Za Zhi. 2017 Oct;42(19):3764-3769.
The present work is to study the chemical constituents from petroleum ether fraction of Tibetan medicine Swertia chirayita by column chromatography and recrystallization. The structures were identified by physical and chemical properties and spectral data as swerchirin (1), decussatin (2), 1,8-dihydroxy-3,5,7-trimethoxyxanthone (3), 1-hydroxy-3,5,7,8-tetramethoxyxanthone (4), bellidifolin (5), 1-hydroxy-3, 7-dimethoxyxanthone (6), Methylswertianin (7), 1-hydroxy-3,5-dimethoxyxanthone (8), erythrodiol (9), oleanolic acid (10), gnetiolactone (11), scopoletin (12), sinapaldehyde (13), syringaldehyde (14), and beta-sitosterol (15). Compounds 3, 4, 9, 11-14 were isolated from S. chirayita for the first time. Compounds 9 and 12 were firstly isolated from the genus Swertia. The cytotoxic activities of compounds 1, 2, 5, 7 and 8 against human pancreatic cancer cell lines SW1990 and BxPC-3,and the protective effects of these compounds against hydrogen peroxide (H2O2)-induced oxidative stress in human endothelium-derived EA.hy926 were investigated in vitro. The results showed no obvious effect at the high concentration of 50 mumol*L(-)(1).
