| 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. |

[Studies on the chemical constituents in root of Gentiana macrophylla from Shaanxi].[Pubmed:16335823]
Zhongguo Zhong Yao Za Zhi. 2005 Oct;30(19):1519-22.
OBJECTIVE: To in vestigate the constituents in root of Gentiana macrophylla. METHOD: Various column chromatographic techniques were used for isolation and purification of the principles. The structures were elucidated on the basis of spectral data (UV, IR, MS, 1H-, 13C-NMR etc.) and identified by comparing with standard substance. RESULT: Eight compounds were identified. Four compounds isolated from the chloroform fraction are: 5-carboxyl-3,4-dihydrogen-1H-2-benzopyran-1-one (1), Erythrocentauric acid (2), roburic acid (3), oleanolic acid (4). Water fraction gave four known secoiridoid glucosides. They were: gentiopicroside (5), swertiamarine (6), sweroside (7), 6'-O-beta-D-glucosylgentiopicroside (8). CONCLUSION: 1 is a novel compound. It was named as Erythrocentauric acid. 2 was isolated from genus Gentiana and 8 was isolated from G. macrophylla for the first time.
