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.

A New Tetracyclic Diterpene from Jatropha curcas[Reference:
WebLink]
METHODS AND RESULTS:
Jatrophodione A (1), a new diterpene with four rings, together with nine known compounds, caniojane (2), jatropholone A (3), jatropholone B (4), jatrogrossidione (5), 2-epijatrogrossidione (6), Heudelotinone (7), gossweilone (8), (3α)-3-hydroxy-ent-pimara-8(14),15-dien-12-one (9), and 12-hydroxy-13-methylpodocarpa-8,11,13-trien-3-one (10), was isolated from the aerial parts of Jatropha curcas. Compounds 5, 6, 9, and 10 were found for the first time in this plant. Their structures were established by spectroscopic analysis, including 2D-NMR spectroscopic techniques. Cytotoxicities of compounds 1, 2, 7, 8, and 9 were tested on the three cancer cell lines A549, Hela, and SMMC-7721.
CONCLUSIONS:
Results showed that 7 exhibited cytotoxicity against SMMC-7721 with an IC50 value of 21.68 μM, whereas 7 and 8 were active against A549 with the IC50 values of 16.04 and 20.47 μM, and against Hela with the IC50 values of 10.67 and 22.83 μM, respectively.

New lathyrane and podocarpane diterpenoids from Jatropha curcas.[Pubmed:
15133216]
METHODS AND RESULTS:
Chemical investigation on Jatropha curcas resulted in the isolation of twenty constituents among which four diterpenoids were unknown and six compounds, tetradecyl-(E)-ferulate, 3-O-(Z)-coumaroyl oleanolic acid, Heudelotinone, epi-isojatrogrossidione, 2alpha-hydroxy-epi-isojatrogrossidione, and 2-methyanthraquinone had not been reported earlier from this species.
CONCLUSIONS:
The structures of the new compounds were established by extensive studies of their 1D- and 2D-NMR spectra.
