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.

Antioxidative action of diterpenoids from Podocarpus nagi.[Pubmed:
9225601 ]
METHODS AND RESULTS:
Diterpenoids, totarol (1), totaradiol (2), 19-hydroxytotarol (3), totaral (4),
4beta-Carboxy-19-nortotarol (5), sugiol (6), isolated from Podocarpus nagi, were evaluated as antioxidants. Microsomal lipid peroxidation induced by Fe(III)-ADP/NADPH and mitochondrial lipid peroxidation induced by Fe(III)-ADP/ NADH were inhibited by these terpenoids. They inhibited linoleic acid autoxidation but not generation of superoxide anion. Totarol (1) protected mitochondrial respiratory enzyme activities against NADPH induced oxidative injury.
CONCLUSIONS:
Totarane diterpenes from P. nagi were shown to be effective to protect biological systems and function against various oxidative stresses.
