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.

Antioxidants from rape (Brassica campestris vir. Japonica Hara) oil cake.[Pubmed:
15143833 ]
METHODS AND RESULTS:
A simple but novel compound, S-1-methoxy-1-(3,5-dimethoxy-4-hydroxyphenyl)ethane, was isolated as a moderately antioxidative compound from rape (Brassica campestris L. subsp. napus) oil cake together with 5 known compounds.
CONCLUSIONS:
Three of these compounds, indolacetonitrile, 4-hydroxyindolacetonitrile, and 4-Hydroxyphenylacetonitrile, showed strong antioxidative activity evaluated by the ferric thiocyanate method.

Volatile and non-volatile chemical constituents of Moringa oleifera Lam., Moringaceae.[Reference:
WebLink]
Phytochemical analysis of the ethanol extract from leaves of Moringa oleifera Lam., Moringaceae, yield the benzylnitriles: niazirine, niazirinine and 4-Hydroxyphenylacetonitrile, while of fruit shells only octacosane was isolated.
METHODS AND RESULTS:
The essential oils from leaves, flowers and fruits were examined by gas chromatography-mass spectrometry. The major constituents identified were: phytol (21.6%) and thymol (9.6%) in the leaves oil, octadecane (27.4%) and hexadecanoic acid (18.4%) in the flowers oil, docosane (32.7%) and tetracosane (24.0%) in the fruits oil.
CONCLUSIONS:
The structures of all compounds were identified by spectroscopic analyses (NMR, IR and MS). 4-Hydroxyphenylacetonitrile is reported for the first time to the Moringa genus and the essential oils of flowers and fruits are reported for the first time to the species M. oleifer.
