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.

Stimulation of osteogenic activity in human osteoblast cells by edible Uraria crinita.[Pubmed:
24785825]
Uraria crinita is an edible herb used as a natural food for childhood skeletal dysplasia.
METHODS AND RESULTS:
Ethyl acetate, n-butanol, and aqueous fractions of a 95% ethanol crude extract of U. crinita were obtained and the active ingredients isolated and purified using a bioguided method. In this manner, we isolated and identified a new active flavone glycoside, apigenin 6-C-β-d-apiofuranosyl(1→2)-α-d-xylopyranoside (3) and 10 known components with stimulatory activity on human osteoblast cells. The new compound 3 at 100 μM significantly increased alkaline phosphatase activity (114.10 ± 4.41%), mineralization (150.10 ± 0.80%), as well as osteopontin (1.39 ± 0.01-fold), bone morphogenetic protein-2 (BMP-2, 1.30 ± 0.04-fold), and runt-related transcription factor 2 (Runx2, 1.43 ± 0.10-fold) mRNA expression through the activation of the BMP-2/Runx2 pathway. Two other components, dalbergioidin (1) and Byzantionoside B (9), displayed similar effects.
CONCLUSIONS:
These results show that U. crinita and its active compounds may have the potential to stimulate bone formation and regeneration.

Structural revisions of blumenol C glucoside and byzantionoside B.[Pubmed:
20190461]
METHODS AND RESULTS:
The absolute stereochemistry of blumenol C glucoside and Byzantionoside B was revised here as (6R,9S)- and (6R,9R)-9-hydroxymegastigman-4-en-3-one 9-O-beta-D-glucopyranosides, respectively, by modified Mosher's method. The empirical rules of (13)C-NMR chemical shift to determine the absolute stereochemistry of C-9 of 9-hydroxymegastigmane 9-O-beta-D-glucopyranoside were also discussed.

[Chemical constituents from the seed coat of Juglans regia].[Pubmed:
22860453]
METHODS AND RESULTS:
Fifteen compounds were isolated from the seed coat of Juglans regia by silica gel, MCI gel and Sephadex LH-20 gel column chromatography, as well as high preparative performance liquid chromatography.
CONCLUSIONS:
Their structures were identified as salidroside (1), (6S, 9S)-roseoside (2), (6S, 9R)-roseoside (3), blumenol C glucoside (4), Byzantionoside B (5), 5-hydroxy-2-methoxy-1, 4-naphthoquinone (6), gallic acid (7), glycerol 1-(9Z-octadecenoate)-2-(9Z, 12Z-octadecadienoate)-3-(9Z, 12Z, 15Z-octadecatrienoate) (8), glycerol 1, 2, 3-tri-(9Z, 12Z-octadecadienoate) (9), glycerol 1, 2, 3-tri-(9Z, 12Z, 15Z-octadecatrienoate) (10), glycerol 1-hexadecanoate-2, 3-di-(9Z, 12Z-octadecadienoate) (11) on the basis of EI-MS, FAB-MS and NMR spectra. Moreover, 35 volatile compounds were identified by GC-MS.
