||The roots of Polygala tenuifolia.
||DMSO, Pyridine, Methanol, Ethanol, etc.
||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: email@example.com
||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.

|Simultaneous determination of phenols in Radix Polygalae by high performance liquid chromatography: quality assurance of herbs from different regions and seasons.[Pubmed: 17722189 ]|
|Radix Polygalae, roots of Polygala tenuifolia or of Polygala sibirica, is a Chinese herbal medicine commonly used to prevent dementia. Reliable chemical markers for quality assurance of this herb are missing. |
METHODS AND RESULTS:
Here, a high performance liquid chromatography method coupled with diode array detection was developed to simultaneously determine nine different phenols in Radix Polygalae, including sibiricose A(5), sibiricose A(6), glomeratose A, tenuifoliside A, glomeratose D, 3',6-di-O-sinapoyl sucrose ester, mangiferin, polygalaxanthone III, and Polygalaxanthone XI.
By using two different detection wavelengths in the HPLC analysis, the developed method was able to determine the phenols with excellent resolution, precision, and recovery.
This established method was therefore applied to determine the amounts of phenols in thirty-two samples from different cultivation regions and harvest seasons in China, and significant variations were revealed. The amounts of phenols in the roots of P. tenuifolia collected in Shanxi and Shannxi Provinces were markedly higher than in roots collected from other Provinces. Moreover, the samples harvested in the spring contained higher contents of phenols than those collected in other seasons.
