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.

Chemical constituents from stem barks of Vernonia cumingiana.[Pubmed: 20822012]

The chemical constituents from the stem barks of Vernonia cumingiana were investigated.
METHODS AND RESULTS:
Various chromatographic techniques such as silica gel chromatography, Sephadex LH-20, ODS column chromatography and HPLC were used to isolate and purify the constituents. The structures were elucidated by spectral methods. Twelve compounds were isolated from the 95% ethanol extract and their structures were elucidated as methyl 3,5-dicaffeoylquinate (1), mEthyl 3,4-dicaffeoylquinate (2), Ethyl 3,4-dicaffeoylquinate (3), methyl 3,4,5-tricaffeoylquinate (4), stigmasterol (5), alpha-spinasterol (6), beta-sitosterol (7), 24-methylene-lanosta-9 (11)-en-3beta-acetate (8), ethyl gallate (9), di-n-butyl-phthalate (10), stearic acid (11) and palmitic acid (12).
CONCLUSIONS:
Compounds 1-12 were isolated from this plant for the first time.
