| 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. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

[Flavonoids from roots of Flemingia philippinensis].[Pubmed:19624015]
Zhongguo Zhong Yao Za Zhi. 2009 Mar;34(6):724-6.
OBJECTIVE: To investigate the chemical constituents of the roots of Flemingia philippinensis. METHOD: Silica gel, ODS silica gel and Sephadex LH-20 column chromatography were employed for the isolation and purification. The structures were identified on the basis of spectral data (MS, 1H-NMR and 13C-NMR) and chemical evidence. RESULT: Seven compounds were isolated from the 75% ethanolic extract of the roots of F. philippinensis and identified as follows: flemiphilippinin D (1), dorsmanins I (2), osajin (3), Eriosematin (4), lupinalbin A (5), genistein (6) and 3'-O-methylorobol (7). CONCLUSION: The compounds 2, 3 and 4 were isolated from the genus Flemingia for the first time. The compounds 2 and 4 were obtained from the Flemingia philippinensis for the first time.
