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: service@chemfaces.com
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.

Insecticidal metabolites from the rhizomes of Veratrum album against adults of Colorado potato beetle, Leptinotarsa decemlineata.[Pubmed:
25146763 ]
METHODS AND RESULTS:
The dried rhizomes of Veratrum album were individually extracted with CHCl3 , acetone, and NH4 OH/benzene to test the toxic effects against the Colorado potato beetle, Leptinotarsa decemlineata, which is an important agricultural pest. Fifteen compounds in various amounts were isolated from the extracts using column and thin-layer chromatography. The chemical structures of 14 compounds were characterized as octacosan-1-ol (1), β-sitosterol (2), stearic acid (3), diosgenin (4), resveratrol (5), Wittifuran X (6), oxyresveratrol (7), β-sitosterol 3-O-β-D-glucopyranoside (8), diosgenin 3-O-α-L-rhamnopyranosyl-(1 → 2)-β-D-glucopyronoside (9), oxyresveratrol 3-O-β-D-glucopyranoside (10), jervine (11), pseudojervine (13), 5,6-dihydro-1-hydroxyjervine (14), and saccharose (15) using UV, IR, MS, (1) H- and (13)C-NMR, and 2D-NMR spectroscopic methods. However, the chemical structure of 12, an oligosaccharide, has not fully been elucidated. Compounds 4, 6, 9, and 10 were isolated from V. album rhizomes for the first time in the current study. The toxic effects of three extracts (acetone, CHCl3 , and NH4 OH/benzene) and six metabolites, 2, 2+4, 5, 7, 8, and 11, were evaluated against the Colorado potato beetle. The assay revealed that all three extracts, and compounds 7, 8, and 11 exhibited potent toxic effects against this pest.
CONCLUSIONS:
This is the first report on the evaluation of the toxic effects of the extracts and secondary metabolites of V. album rhizomes against L. decemlineata. Based on these results, it can be concluded that the extracts can be used as natural insecticides.

Bioactive 2-arylbenzofuran derivatives from Morus wittiorum.[Pubmed:
20362036]
METHODS AND RESULTS:
Investigation of an ethanol extract from the stem bark of Morus wittiorum led to the isolation of five new 2-arylbenzofuran derivatives that were named wittifuran S, wittifuran T, wittifuran V, wittifuran W and Wittifuran X (1-5). Structures were determined on the basis of spectroscopic analysis.
CONCLUSIONS:
Two new wittifurans and five previously isolated compounds were assayed for antioxidant and anti-inflammatory activity.
