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

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.

Separation and identification of new sucrose esters from root of Polygala tenuifolia Willd[Reference: WebLink]

To study the constituents of the extract from the root of Polygala tenuifolia Willd.
METHODS AND RESULTS:
The chemical constituents were isolated by silica,Sephadex LH-20 gel column chromatography and HPLC.Chemical characters and spectroscopic analysis were employed for the structural identification. Eleven compounds were obtained and their structures were identified as sibiricose A5(1),tenuifolioside A(α-D-glucopyranoside,3-O-[(2Z)-3-(4-hydroxy-3-methoxyphenyl)-1-oxo-2-propen-1-yl]-β-D-fructofuranosyl,2),tenuifolioside B(α-D-glucopyranoside,3-O-[(2E)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]-β-D-fructofuranosyl,3),tenuifolioside C(α-D-glucopyranoside,3-O-[(2Z)-3-(3,4-dimethoxyphenyl)-1-oxo-2-propen-1-yl]-β-D-fructofuranosyl,4),sibiricose A6(5),glomeratose A(6),sibiricaxanthone B(7),polygalaxanthone Ⅺ(8),1,2,3,7-Tetramethoxyxanthone(9),onjixanthoneⅡ(10),and polygitol(11).
CONCLUSIONS:
Compounds 24,named tenuifolioside A-C respectively,are new sucrose esters which have not been reported before.
