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.

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.

Photo-activated DNA binding and antimicrobial activities of furoquinoline and pyranoquinolone alkaloids from rutaceae.[Pubmed:
15229804]
To find novel photo-active compounds of potential use in photochemotherapy from higher plants, photo-activated antimicrobial and DNA binding activities of the furoquinolines, skimmianine, kokusaginine, and Haplopine, and a pyranoquinolone, flindersine, from two species of Rutaceae plants were investigated.
METHODS AND RESULTS:
TLC overlay assays against a methichillin-resistant strain of Staphylococcus aureus and Candida albicans were employed to test antimicrobial properties. All of the tested compounds showed photo-activated antimicrobial activity against S. aureus in the order of kokusaginine > Haplopine, flindersine > skimmianine. Weaker activity was found for C. albicans. Photo-activated DNA binding activity of these compounds was investigated by a method using restriction enzymes and a specially designed 1.5 kb DNA fragment. Kokusaginine showed inhibition against all of the 16 restriction enzymes. Haplopine showed a similar inhibition pattern but the binding activity against Asc I and Sma I with restriction sequences consisting only of G and C was very weak. Skimmianine showed binding activity against Xba I, BciV I, Sal I, Pst I, Sph I and Hind III, but very weak or no activity was found for the other restriction enzymes. A pyranoquinolone, flindersine, showed no activity against any of the restriction enzymes.
CONCLUSIONS:
Photo-activated DNA binding activity of furoquinolines was therefore in the order of kokusaginine > Haplopine > skimmianine, which was the same order as their photo-activated antimicrobial activity against S. aureus.

Melanogenesis-Inhibitory and Cytotoxic Activities of Limonoids, Alkaloids, and Phenolic Compounds from Phellodendron amurense Bark.[Pubmed:
28425165 ]
Four limonoids, 1 - 4, five alkaloids, 5 - 9, and four phenolic compounds, 10 - 13, were isolated from a MeOH extract of the bark of Phellodendron amurense (Rutaceae).
METHODS AND RESULTS:
Among these, compound 13 was new, and its structure was established as rel-(1R,2R,3R)-5-hydroxy-3-(4-hydroxy-3-methoxyphenyl)-6-methoxy-1-(methoxycarbonylmethyl)indane-2-carboxylic acid methyl ester (γ-di(methyl ferulate)) based on the spectrometric analysis. Upon evaluation of compounds 1 - 13 against the melanogenesis in the B16 melanoma cells induced with α-melanocyte-stimulating hormone (α-MSH), four compounds, limonin (1), noroxyhydrastinine (6), Haplopine (7), and 4-methoxy-1-methylquinolin-2(1H)-one (8), exhibited potent melanogenesis-inhibitory activities with almost no toxicity to the cells. Western blot analysis revealed that compound 6 inhibited melanogenesis, at least in part, by inhibiting the expression of protein levels of tyrosinase, TRP-1, and TRP-2 in α-MSH-stimulated B16 melanoma cells. In addition, when compounds 1 - 13 were evaluated for their cytotoxic activities against leukemia (HL60), lung (A549), duodenum (AZ521), and breast (SK-BR-3) cancer cell lines, five compounds, berberine (5), 8, canthin-6-one (9), α-di-(methyl ferulate) (12), and 13, exhibited cytotoxicities against one or more cancer cell lines with IC50 values in the range of 2.6 - 90.0 μm.
CONCLUSIONS:
In particular, compound 5 exhibited strong cytotoxicity against AZ521 (IC50 2.6 μm) which was superior to that of the reference cisplatin (IC50 9.5 μm).

In vivo and in vitro production of alkaloids by Haplophyllum patavinum.[Pubmed:
11990434]
A protocol for shoot induction from callus of Haplophyllum patavinum was established.
METHODS AND RESULTS:
Two known furoquinoline (skimmianine and Haplopine), and three quinolone (edulinine, ribalinine and isoplatydesmine) alkaloids were isolated for the first time from plant material, callus and shoot cultures of this species. The structures of these compounds have been characterised on the basis of spectroscopic evidence.
