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.

Estimation of twelve bacopa saponins in Bacopa monnieri extracts and formulations by high-performance liquid chromatography.[Pubmed:
16755069]
METHODS AND RESULTS:
A simple and sensitive reversed phase high performance liquid chromatographic (HPLC) method has been developed for the simultaneous determination of twelve bacopa saponins present in the extracts of the Indian Medicinal Plant, Bacopa monnieri. The separation was achieved on a reversed phase C(18) column (Luna C(18)), 5 microm by isocratic elution with 0.05 M sodium sulphate buffer (pH 2.3) and acetonitrile (68.5 : 31.5, v/v) as the mobile phase at a flow rate of 1.0 ml/min with an operating temperature of 30 degrees C. The method was validated for linearity, precision, intra- and inter-day precision and accuracy. Several Bacopa samples (plant materials, extracts and commercial formulations) were successfully analyzed. Major bacopasaponins were bacosides A(3) (3), bacopaside II (4), bacopaside I (5), bacopaside X (6), bacopasaponin C (7), bacopaside N2 (9) and the minor components were bacopasaponin F (1), bacopasaponin E (2), bacopaside N1 (8) bacopaside III (10), bacopaside IV (11) and Bacopaside V (12).
CONCLUSIONS:
The total saponin content in the samples, plant materials and extracts varied from 5.1 to 22.17% and 1.47 to 66.03 mg/capsule or tablet in the commercial formulations.
