| 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 investigation of the roots of Polygala sibirica L.[Pubmed:24702811]
Chin J Nat Med. 2014 Mar;12(3):225-8.
AIM: To investigate the chemical constituents of the roots of Polygala sibirica L. (Polygalaceae) METHOD: The isolation was performed by solvent extraction and various chromatographic techniques, including silica gel, Sephadex LH-20, ODS, semi-preparative HPLC, and preparative TLC. The chemical structures were elucidated based on extensive spectroscopic analysis, including HR-ESI-MS and 1D- and 2D-NMR spectroscopic data. RESULTS: A total of sixteen compounds, including five xanthones (5, 7-10), five saccharide esters (1, 3, 4, 12, 13), two flavonoids (14, 16), two triterpenoids (11, 15), one phenylpropanoid (6), and one benzophenone glycoside (2) were isolated. Their structures were determined as sibiricose A7 (1), sibiriphenone A (2), polygalatenoside A (3), polygalatenoside C (4), lancerin (5), 3, 4, 5-trimethoxycinnamic acid (6), 6-hydroxy-1, 2, 3, 7-tetramethoxyxanthone (7), 1, 3, 7-trihydroxy-2-methoxyxanthone (8), Onjixanthone II (9), 1, 2, 3, 6, 7-pentamethoxyxanthone (10), presenegenin (11), 3'-O-3, 4, 5-trimethoxycinnamoyl-6-O-4-methoxy benzoyl sucrose (12), tenuifoliside C (13), 5, 3'-dihydroxy-7, 4'-dimethoxyflavonol-3-O-beta-D-glucopyranoside (14), tenuifolin (15), and rhamnetin 3-O-beta-D-glucopyranoside (16). CONCLUSION: Compounds 1 and 2 are two new compounds from P. sibirica.
