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.

Effect of Baccharis dracunculifolia D.C. (Asteraceae) extracts and its isolated compounds on macrophage activation.[Pubmed:
17331351]
Baccharis dracunculifolia D.C. (Asteraceae), a shrub which grows wild in Brazil, is the main botanical source of Brazilian green propolis.
METHODS AND RESULTS:
Since Brazilian propolis shows an immunomodulatory activity, the goal of this work was to evaluate the action of B. dracunculifolia extracts and some of its isolated compounds on reactive oxygen intermediate (H(2)O(2)) production by macrophages obtained from male BALB/c mice. The results showed that the leaf (Bd-L) (25, 50, and 100 microg mL(-1)), leaf rinse (Bd-LR) (25 microg mL(-1)), and the root (Bd-R) (25 microg mL(-1)) extracts enhanced H2O2 release by macrophages. A phytochemical study of the root and leaves of B. dracunculifolia was carried out. The chromatographic fractionation of Bd-R, using several techniques, afforded the isolation of baccharis oxide (1), Friedelanol (2), viscidone (11), 11-hydroxy-10,11-dihydro-euparin (12), and 6hydroxy-tremetona (13), while Bd-LR gave the following isolated compounds: baccharis oxide (1), Friedelanol (2), isosakuranetin (3), aromadendrin-4'-methyl ether (4), dihydrocumaric acid (5), baccharin (6), hautriwaic acid lactone (7), hautriwaic acid acetate (8), drupanin (9), and cumaric acid (10). Among the isolated compounds, baccharis oxide (1) and Friedelanol (2) increased H2O2 production at a concentration of 100 microM.
CONCLUSIONS:
This is the first time that the presence of compounds 7, 8, 12, and 13 in B. dracunculifolia has been reported. Based on these results it is suggested that the crude extracts and some isolated compounds from B. dracunculifolia display an immunomodulatory action.

Chemical Constituents of Lecythispisonis (Lecythidaceae)--A New Saponin and Complete 1H and 13C Chemical Shift Assignments.[Pubmed:
26197504]
METHODS AND RESULTS:
A novel triterpenoid saponin 3-O-β-D-glucuronopyranosyl-(1' --> 3)-2α,19α-dihydroxyolean-12-en-28-oic acid [3-O-β-D-glucuronopyranosyl-(1' --> 3)-arjunic acid, 1], ten known compounds [six triterpenoids: α-amyrin (2), β-amyrin (3), germanicol (4), lupeol (5), friedelin (6), Friedelanol (7); four steroids--campesterol (8), stigmasterol (9), sitosterol (10), cholesterol (11)], and a long chain alcohol n-eicosan-1-ol (12) were identified in the bark of Lecythis pisonis.
CONCLUSIONS:
The structures were established by 1D and 2D NMR spectroscopy (1H and 13C-NMR, DEPTQ, 1H-1H-COSY, NOESY, HSQC and HMBC), low (CG-MS) and high resolution mass spectrometry (HR-ESI-MS), and infrared (IR) spectral data involving comparison with the literature.
