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.

[Studies on chemical constituents of phenols in fresh Houttuynia cordata][Pubmed:
17655149]
Objective: To study the aqueous constituents of Houttuynia cordata.
Method: Various columns including Diaion HP-20, Sephadex LH-20, ODS and silica gel were employed for the isolation and purification of compounds from H. cordata. The structures of the compounds were identified by physiochemical properties and spectral analysis.
Result: Five compounds were isolated, and their structures were identified as chlorogenic methyl ester (1), (E)-4-Hydroxy-4-[3'-(beta-D-glucopyranosyloxy) butylidene]-3, 5, 5-trimethyl-2-cyclohexen-1-one (2), 2-(3, 4-dihydroxyphenyl) ethyl-beta-D-glucopyranoside (3), p-hydroxyphenethyl-beta-D-glucoside (4), 4-(beta-D-glucopyranosyloxy)-3-hydroxy-Benzoic acid (5).
Conclusion: All compounds were isolated from this plant for the first time.
