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. |

Three biflavonoids from ethanol extract of the root of Daphne genkwa.[Pubmed:16220789]
Yao Xue Xue Bao. 2005 May;40(5):438-42.
AIM: To investigate the chemical constituents of the secondary metabolites of the roots of Daphne genkwa. METHODS: The roots of D. genkwa were extracted with 95% ethanol at 60-70 degrees C for 7 days to obtain the crude extract. The crude extract was purified by silica gel and Sephadex LH-20 column chromatography as well as the HPLC techniques. The structures of the isolates were elucidated by combined spectroscopic methods including 1D and 2D NMR, MS, UV, IR and CD. RESULTS: Three new biflavonoids were isolated from the ethanol extract of the roots of D. genkwa and their structures were identified as Daphnodorin H-3-methyl ether (1), Daphnodorin H-3"-methyl ether (2) and daphnodorin G-3"-methyl ether (3). CONCLUSION: Compounds 1, 2 and 3 are three new biflavonoids.
