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.

Source of Epimagnolin A
The dried flower buds of Magnolia biondii Pamp.
Biological Activity of Epimagnolin A
| Description | Epimagnolin A affects the transport activity of ABCB1(a major transmembrane efflux pump belonging to the ABC transporter superfamily), it also exhibits growth inhibitory activity against larvae of Drosophila melanogaster. |
| Targets | ATPase | ABCB1 |
| In vitro |
An insect growth inhibitory lignan from flower buds of Magnolia fargesii.[Reference: WebLink] Phytochemistry, 1994, 35(00):611–613. Bioassay-guided isolation afforded a new lignan, (+)-Epimagnolin A, from the flower buds of Magnolia fargesii. This lignan exhibited growth inhibitory activity against larvae of Drosophila melanogaster. The structure of a new lignan was determined on the basis of spectral methods. |
Protocol of Epimagnolin A
| Kinase Assay |
Preparation of epimagnolin A, a tetrahydrofurofuranoid lignan from Magnolia sp., and evaluation of anti-drug-resistance activity.[Reference: WebLink] Planta Med 2016; 82(S 01): S1-S381. Herbal products have been used to treat or prevent health problems for a long time. Although the biological effects of these products have been reported, their safety still remains to be elucidated. Therefore, studies are required to ensure their safe use. Among the herbal products listed in the Korean, Chinese, and Japanese Pharmacopoeias, Shin-i (Xin-yi/Flos magnoliae), dried flower buds of Magnolia fargesii or M. flos are one of the most commonly used traditional herbs for the treatment of allergic rhinitis, emphysema, headache, nasal congestion, and sinusitis. Tetrahydrofurofuranoid lignans, such as aschantin, dimethoxyaschantin, dimethylliroresinol, dimethylpinoresinol, Epimagnolin A, fargesin, and magnolin extracted from Shin-i have effects, such as anti-angiogenic, anti-allergic, anti-diabetic, anti-inflammatory, anti-microbial, and anti-rheumatoid arthritis. Among them, the pharmacokinetics of Epimagnolin A and magnolin have been reported, but not their molecular mechanisms. |

Isolation and purification of lignans from Magnolia biondii Pamp by isocratic reversed-phase two-dimensional liquid chromatography following microwave-assisted extraction.[Pubmed:17628872]
J Sep Sci. 2007 Oct;30(15):2370-81.
The dried flower buds of Magnolia biondii Pamp are one of the most widely used medicinal plants officially listed in the Chinese Pharmacopoeia. A 2-D column-switching system without sample loop trapping, where two columns were switched directly via a six-port two-position switching valve, was successfully applied for the first time to the isolation and purification of five lignans including pinoresinol dimethyl ether, magnolin, epi-magnolin A, fargesin, and demethoxyaschantin from M. biondii Pamp after microwave-assisted extraction. The introduction of the six-port switching valve instead of sample loop assured 100% recovery from the first dimension to the second, and the injection volumes of the second dimension could reach 12 mL. In this mode of operation, the solvent consumption of the 2-D approach was less than 30% that of conventional gradient methods with even larger sample size. The simultaneous operations of the two dimensions allowed the cycle time to be less than 16 min, compared to 90 min in the gradient elution single-dimension mode of operation. All of the five lignans were isolated at high purities of over 99% with approximately 95% recoveries.
