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.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

A Phenylpropanoid Glycoside as a Calcineurin Inhibitor Isolated from Magnolia obovata Thunb.[Pubmed: 26174771 ]

J Microbiol Biotechnol. 2015 Sep;25(9):1429-32.


METHODS AND RESULTS:
To identify plant-derived cell signaling inhibitors with antifungal properties, a twocomponent screening system using both wild-type Cryptococcus neoformans and a calcineurin mutant was employed owing to their counter-regulatory actions on the Hog1 mitogenactivated protein kinase and calcineurin pathways. Of the 2,000 plant extracts evaluated, a single bioactive compound from M. obovata Thunb. was found to act specifically on the calcineurin pathway of C. neoformans.
CONCLUSIONS:
This compound was identified as Magnoloside A, and had potent antifungal activities against various Cryptococcus strains with minimum inhibitory concentration values ranging from 1.0 to 4.0 μg/ml.

An HPLC-DAD Method for Simultaneous Quantitative Determination of Four Active Hydrophilic Compounds in Magnoliae Officinalis Cortex.[Pubmed: 25085894]

Magnoliae officinalis cortex (MOC), derived from Magnolia officinalis and its variation M. officinalis var. biloba, is an important traditional Chinese medicine.
METHODS AND RESULTS:
In our previous work, 11 hydrophilic ingredients of MOC were isolated and structurally elucidated and four, namely syringin (SG), Magnoloside A (MA), magnoloside B (MB) and magnoflorine (MF), showed bioactive effects. Herein, we describe an HPLC-DAD method for the simultaneous quantitative determination of MA, MB, MF and SG in MOC for the first time. The chromatographic separation of samples was performed on an Agilent Zorbax SB-C18 column (250 × 4.6 mm i.d., 5 µm) by gradient elution with water-acetic acid (pH 3.0) and methanol at a flow rate of 1.0 mL/min. The wavelengths were set at 265 nm for MF and SG, and 328 nm for MA and MB. The average recovery of the four compounds was from 97.63 to 103.84%. Nearly 100 MOC samples harvested from eight habitats were analyzed in which the contents of the tested compound varied in the range of 0.016-0.350% (MF), 0.010-0.337% (SG), 0.017-3.009% (MB) and 0.077-2.529% (MA).
CONCLUSIONS:
The analysis also indicated that MOC contains a significant amount of phenylethanoid glycosides. This was an unexpected finding because previously lignan was considered to be the main component of MOC.
