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.

DIURETIC AND ANTI-DIURETIC BIOACTIVITY DIFFERENCES OF THE SEED AND SHELL EXTRACTS OF ALPINIA OXYPHYLLA FRUIT[Pubmed:
28487890]
Background: Alpinia oxyphylla fruit (AOF, Yizhi in Chinese) is a well-known traditional Chinese medicine as an anti-diuretic agent and composed of two parts i.e. seed and shell. These two parts have different components, but the bioactivity differences of the two parts are not clear. This study aims to evaluate the different anti-diuretic effects of the seed and shell of AOF.
Materials and methods: The potential bioactive components were analyzed by UPLC-Q-TOF-MS. The diuretic and anti-diuretic activity was determined with saline-loads rats.
Results: The results showed that the 200 mg/kg and 400mg/kg of SREAO displayed a short-time anti-diuretic activity 1h after administration and then a significant diuretic activity was being observed at 5-6 h in 400mg/kg group of SREAO. And the 400mg/kg doses of SREAO also showed a remarkable increase for electrolyte excretion of K. Three sesquiterpene compounds, namely oxyphyllol A (1), Oxyphyllol B (2), and nootkatone (3) were identified from the active SREAO fraction by UHPLC-ESI-Q-TOF/MS. +
Conclusion: The seed part of Alpinia oxyphylla possessed pronounced diuretic and anti-diuretic effect. The sesquiterpene components are the major constituents and possibly contributed the diuretic and anti-diuretic activity.
