| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

[Chemical constituents of Swertia patens].[Pubmed:27062819]
Zhongguo Zhong Yao Za Zhi. 2015 Oct;40(20):4012-7.
Chemical constituents of Swertia patens. The whole plant of air-dried Swertia patens was extracted with 90% EtOH. The water extract was suspended in H(2)O and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isola- ted and purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses (MS, (1)H-NMR, (1)(3)C- NMR). Eighteen compounds were isolated and elucidated as 3, 4-dihydro-1H,6H,8H-naptho [1,2-c:4,5-c', d'dipyrano-1, 8-dione (1), angelone (2), gentiogenal (3), erythricin (4), Erythrocentaurin (5), gentianine (6), swertiakoside B (7), swertiamarin (8), 2'-O-actylswertiamarin (9), amarogentin (10), 1, 3, 5-trihydroxyxanthone (11), 1, 3-dihydroxy-5-methoxyxanthone (12), 1-hydroxy- 2, 3, 5-trimethoxyxanthone (13), gentiocrucine (14), 3-hydroxyphenylketone (15), n-hexacosyl ester 4-hydroxy-trans-cinnamate (16), n-hexacosyl ester 4-hydroxy-cis-cinnamate (17), and cholest-4-en-3-one (18). Compounds 1-7, 9-18 were obtained from S. patens for the first time.
Rapid preparative isolation of erythrocentaurin from Enicostemma littorale by medium-pressure liquid chromatography, its estimation by high-pressure thin-layer chromatography, and its alpha-amylase inhibitory activity.[Pubmed:25504557]
J Sep Sci. 2015 Feb;38(4):592-8.
Erythrocentaurin is a relatively simple natural product present among the members of Gentianaceae. A preparative method for the isolation of Erythrocentaurin from the ethyl acetate fraction of Enicostemma littorale using medium-pressure liquid chromatography has been reported. The method consisted of a simple step gradient from 10 to 20% ethyl acetate in n-hexane. Using a 70 x 460 mm Si60 column, this method is capable of processing 20 g of material in <3 h (purity approximately 97%). The recovery of Erythrocentaurin was 87.77%. Estimation of Erythrocentaurin in extracts and fractions based on high-pressure thin-layer chromatography was carried out on silica gel 60 F(254) plates with toluene/ethyl acetate/formic acid (80:18:2 v/v/v) as the mobile phase. The densitometric analysis was performed at 230 nm. A well-separated compact band of Erythrocentaurin appeared at R(f )0.54 +/- 0.04. The analytical method showed good linearity in the concentration range of 200-1500 ng/band with a correlation coefficient of 0.99417. The limits of detection and quantification were found to be approximately 60 and approximately 180 ng/band, respectively. Erythrocentaurin exhibited a concentration-dependent alpha-amylase inhibition (IC(50) 1.67 +/- 0.28 mg/mL). The outcome of the study should be considered for pharmacokinetic and biotransformation studies involving E. littorale.
Phytochemical studies and antibacterial activity of Centaurium pulchellum Druce.[Pubmed:16854716]
Nat Prod Res. 2006 Aug;20(10):896-901.
Two isocoumarin derivatives, one new, erythricin (1) and a known Erythrocentaurin (2) were isolated from the whole plant of Centaurium pulchellum Druce. The 13C-NMR data of compound 2 are described. The structures of compounds 1, 2 were elucidated on the basis of spectral analysis including 2D-NMR experiments. Antibacterial and brine shrimp lethality assays are also described on the fractions of the plant extract.
