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.

Antioxidant and anticancer constituents from the leaves of Liriodendron tulipifera.[Pubmed:
24705566]
METHODS AND RESULTS:
Sixteen compounds were extracted and purified from the leaves of Liriodendron tulipifera. These compounds include aporphines, oxoaporphine, coumarin, sesquiterpene lactone, benzenoids, cyclitol and steroids. (+)-Norstephalagine (2) (an aporphine) and scopoletin (8) (a coumarin) were isolated from Liriodendron tulipifera leaves from the first time. The identified compounds were screened for their antiradical scavenging, metal chelating and ferric reducing power activities. The results have showed that these compounds have antioxidative activity. The study has also examined the chemopreventive property of the isolated compounds against human melanoma cells A375. The results shown that (-)-anonaine (1), (-)-liridinine (3), (+)-Lirinidine (6), lysicamine (7) and epitulipinolide diepoxide (9) significantly inhibited the proliferation of melanoma cells.
CONCLUSIONS:
These results revealed that these compounds have antioxidative activity and chemopreventive activity in skin melanoma cells.

Two new 7-dehydroaporphine alkaloids and antiplatelet action aporphines from the leaves of Annona purpurea.[Pubmed:
9883592]
METHODS AND RESULTS:
Bioactivity-directed fractionation led to the isolation of two new 7-dehydroaporphine alkaloids, 7-hydroxy-dehydrothalicsimidine (1) and 7-formyl-dehydrothalicsimidine (2), along with the five known alkaloids, thalicsimidine (3), norpurpureine (4), N-methyllaurotetanine (5), Lirinidine (6) and N-methylasimilobine (7), from the leaves of Annona purpurea.
CONCLUSIONS:
Structural elucidation of these compounds was established by mass and spectroscopic analyses. Among them, 1, 3, 4, 6 and 7 exhibited significant inhibition of collagen, arachidonic acid and platelet activating factor-induced platelet aggregation; 1 also showed inhibition against thrombin-induced platelet aggregation.
