||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.

|Two New Compounds from the Roots of Rheum palmatum.[Reference: WebLink]|
|To study the constituents of Rheum palmatum.|
METHODS AND RESULTS:
Chromatographic separations of silica gel and polyamide were used. All the structures were elucidated on the basis of chemical and spectroscopic analysis. Nine compounds were isolated and their structure were identified as 2, 5-dimethyl-6, 8-dihydroxy-chromone (1), 1-methyl-2, 8-dihydroxy- 3-carboxy −9, 10-anthraquinone (2), citreorosein (3), 4-(4-hydroxyphenyl)-2-butanone (4), 4-(4-hydroxyphenyl)-2-butanone-4′-O-β-D- (2″-galloyl-6″-O-p-coumaroyl)-glucopyranoside (5), trans-3, 5, 4′-trihydroxystilbene-4′-O-β-D-(6″-galloyl)-glucopyranoside (6), 4-(4- hydroxyphenyl)-2-butanone-4′-O-β-D-(6″-O-cinnamoyl)-glucopyranoside (7), 4-(4-hydroxyphenyl)-2-butanone-4′-O-β-D-(6″-O-p-coumaroyl)-glucopyranoside (8), trans-3, 5, 4′-trihydroxystilbene-4′-O-β-D-glucopyranoside (9).
Compounds 1 and 2 were newly isolated from Rheum palmatum.
