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.

Biologically active carbazole alkaloids from Murraya koenigii.[Pubmed:
10563914]
METHODS AND RESULTS:
The bioassay guided fractionation of the acetone extract of the fresh leaves of Murraya koenigii resulted in the isolation of three bioactive carbazole alkaloids, mahanimbine (1), Murrayanol (2), and mahanine (3), as confirmed from their (1)H and (13)C NMR spectral data. Compound 2 showed an IC(50) of 109 microg/mL against hPGHS-1 and an IC(50) of 218 microg/mL against hPGHS-2 in antiinflammatory assays, while compound 1 displayed antioxidant activity at 33.1 microg/mL.
CONCLUSIONS:
All three compounds were mosquitocidal and antimicrobial and exhibited topoisomerase I and II inhibition activities.
