Biological Activity
Description: (+/-)-Puerol B shows inhibitory activity on AGEs formation in vitro.
In vitro:
Arch Pharm Res. 2010 Oct;33(10):1651-4.
Phenolic compounds from Pueraria lobata protect PC12 cells against Aβ-induced toxicity.[Pubmed: 21052940 ]

METHODS AND RESULTS:
Bioassay-guided fractionation of the EtOAc-soluble extract of Pueraria lobata based on the inhibition of Aβ-induced toxicity in PC12 cells resulted in the isolation of four known active compounds, genistein (8), biochanin A (9), sissotrin (10), and Puerol B (11). Of these, genistein (8) and biochanin A (9) exhibited potent neuroprotective effects with ED(50) values of 33.7 and 27.8 μM, respectively. In addition, a new coumestan, 2-(α,α-dimethylallyl)coumestrol (1) was isolated and characterized, but proved to be inactive, as were additional seven known compounds. The structure of new compound 1 was determined using spectroscopic techniques.
Arch Pharm Res. 2006 Oct;29(10):821-5.
Constituents of the roots of Pueraria lobata inhibit formation of advanced glycation end products (AGEs).[Pubmed: 17121174 ]

METHODS AND RESULTS:
Two isoflavone C-glucosides, puerarin (1) and PG-3 (2), a but-2-enolide, (+/-)-Puerol B (3), two isoflavone O-glucosides, daidzin (4) and genistin (5), and three pterocarpans, (-)-medicarpin (6), (-)-glycinol (7) and (-)-tuberosin (8), were isolated from a MeOH extract of the roots of Pueraria lobata, using an in vitro bioassay based on the inhibition of the formation of advanced glycation end products (AGEs) to monitor chromatographic fractionation. The structures of 1-8 were determined by spectroscopic data interpretation, particularly by 1D- and 2D-NMR studies, and by comparison of these data with values in the literature. All of the isolates (1-8) were evaluated for their inhibitory activity on AGEs formation in vitro.
CONCLUSIONS:
Of these, puerarin (1), PG-3 (2), and (+/-)-Puerol B (3) exhibited more potent inhibitory activity than the positive control aminoguanidine.
Puerol B Description
Source: The stem barks of Sophora japonica.
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
