| 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 Polygala tenuifolia root].[Pubmed:25857159]
Zhong Yao Cai. 2014 Sep;37(9):1594-6.
OBJECTIVE: To study the chemical constituents from the root of Polygala tenuifolia. METHODS: Silica gel,Sephadex LH-20 and ODS chromatographic techniques were used to study the chemical constituents of Polygala tenuifolia, and the chemical structures were elucidated by application of spectral data. RESULTS: Eight-compounds were obtained and their structure were identified as 7-hydroxy-1-methoxy-2,3-methylenedioxyxanthone(1), 1, 7-dihydroxy-2, 3-dimethoxyxanth one(2), 1,3,6-trihydroxy-2, 7-dimethoxyxanthone(3),7-hydroxy-1,2, 3-trimethoxyxanthone(4), 1,2,3,6, 7-pentamethoxyxanthone(5), 1,3, 7-trihydroxy-2, 6-dimethanoxyxanthone (6),7-hydroxy-1-methoxyxanthone(7) and 1,7-dihydroxy-3,4-dimethoxyxanthone(8). CONCLUSION: Compounds 1,6,7 and 8 are isolated from Polygala tenuifolia for the first time.
