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.

Chromenone Glucosides Acylated with Monoterpene Acids from the Leaves of Eucalyptus camaldulensis var. obtusa[Reference:
WebLink]
METHODS AND RESULTS:
Three new chromenone glucosides acylated with monoterpene acids, eucamaldusides A (1), B (2), and C (3), were isolated from the leaves of Eucalyptus camaldulensis var. obtusa, together with the five known compounds ursolic acid lactone, Obtusilin, β-sitosterol glucoside, 4-hydroxybenzoic acid, and cypellocarpin C. The structures of the new compounds were established by exhaustive 1D- and 2D-NMR spectroscopic studies.
CONCLUSIONS:
Their configuration was determined by measuring the [α]D of the known methyl esters of the monoterpene acids obtained by methanolysis of 1–3.
