||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.
Need more advice on solubility, usage and handling? Please email to: firstname.lastname@example.org
||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.

|[Glucosides from Pleurospermum rivulorum].[Pubmed: 12585084]|
|To study the chemical constituents of Pleurospermum rivulorum.
To separate the constituents of P. rivulorum by using various kinds of chromatography and identify their structures on the basis of spectral analysis.
Four glucosides were isolated from P. rivulorum. Their structures were established as marmesinin (I), tert-O-beta-D-glucopyranosyl-heraclenol (II), 1'-O-beta-D-glucopyranosyl (2R, 3S)-3-hydroxynodakenetin (III) and 8-hydroxy-5-O-beta-D-glucopyranosyl-psoralen (IV) based on the analysis of spectral data of IR, UV, MS, 1D and 2D-NMR.
Compounds III and IV are new compounds. All of the four compounds were isolated from this plant for the first time.
