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.

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.

Structural Elucidation of Tectoruside Isolated from Iris tectorum Maxim.by NMR Spectroscopy.[Reference:
WebLink]
METHODS AND RESULTS:
The chemical constituents of Iris tectorum Maxim.were extracted with 95% alcohol,isolated by column chromatography on silica gel,and purified by recrystallization.
The structures of the compounds were analyzed on the basis of the spectral data.A phenolic diglycoside,Tectoruside,was isolated from the n-Butanol portion of the extract,and its structure was elucidated by various spectroscopic data,including 2D NMR.
CONCLUSIONS:
The 1H and 13C NMR chemical shifts of the compounds were assigned.Its structure was found to be 1-{3′-methoxy-4′-[O-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl]phenyl}ethanone.
