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.

Isolation and characterization of miscellaneous terpenoids of Schisandra chinensis[Reference:
WebLink]
METHODS AND RESULTS:
Two new bisnortriterpenoids with 18-norschiartane skeleton, wuweizidilactones G (1) and H (2), four new highly oxygenated nortriterpenoids based on a schisanartane skeleton, schindilactones D–G (3–6), a pre-schisanartane skeleton, Pre-schisanartanin B (7), and a novel 3,4-seco-21,26-olide-artane triterpenoid wuweizilactone acid (8), along with 24 known terpenoids with different carbon frameworks, have been isolated from the acetone extract of the stems and leaves of Schisandra chinensis. The terpenoids produced by this plant have chemical diversity.
CONCLUSIONS:
The structures of new compounds 1–8 have been characterized by spectroscopic data interpretation. The cytotoxicity and anti-HIV-1 activity of all the Schisandra nortriterpenoids were evaluated.
