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.

Sesquiterpenoids of Coniogramme maxima.[Pubmed: 22792795]

METHODS AND RESULTS:
Fifteen compounds were separated by chromatography technique. Their structures were determined by spectral data, including 10 sesquiterpenoids as (3S)-pteroside D (1), Epipterosin L (2), pterosin D (3), onitin (4), pterosin Z (5), onitisin (6), onitisin-glucopyranoside (7), onitin-15-O-beta-D-glucopyranoside (8), (2S,3R)-pterosin-L-2'-O-beta-D-glucopyranoside (9) and (3R)-peterosin D-3-O-beta-D-glucopyranoside (10). The other compounds were uracil (11), 3,4-dihydroxybenzaldehyde (12), 5-hydroxymethyl-2-furancarboxaldehyde (13), beta-sitosterol (14) and daucosterol (15).
CONCLUSIONS:
The above 15 compounds are separated from C. maxima for the first time, including 9 compounds being first separated from genus Coniogramme.
