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.

Chemical constituents of ethyl acetate extract from Polygonum perfoliatum.[Pubmed:
23252271]
METHODS AND RESULTS:
The chemical constituents of Polygonum perfoliatum were isolated and purified by chromatography on silica gel, Sephadex LH-20 and Semi-preparative HPLC. The structures of compounds were elucidated and identified by physicochemical properties, H-NMR, 13C-NMR and ESI-MS. Ten compounds were isolated and identified as 5-hydroxymethyl-2-furaldEhyde (1), methyl caffeoate (2), protocatechuic aldehyde (3), quercetin (4), pinocernbrin (5), catechin (6), taxifolin (7), Taxifolin 3-O-beta-D-xylopyranoside (8), 13-epitorulosal (9), coumarin-7-O-beta-D-glucose glycosidic (10).
CONCLUSIONS:
Compounds 6-9 are isolated from this plant for the first time.
