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.

Studies on constituents of rootsanel leaves from Desmodium blandum and their cytotoxic activity against growth of several tumor cells.[Pubmed:
19160788]
To investigate the chemical constituents of Desmodium blandum and their cytotoxic activity against the growth of several tumor cells.
METHODS AND RESULTS:
Various chromatographic techniques including silica gel, Sephadex LH-20 column chromatography were employed for the isolation and purification of the constituents. The structures of compounds were elucidated by spectral analyses (IR, UV, NMR, MS). Their cytotoxic activity was then studied.
Eight compounds were isolated from the stems of D. blandum and identified as N, N-dimethyltryptamine (1), 5-methoxy-N, N-dimethyltryptamine (2), citrusinol (3), Yukovanol (4), (Z)-1-(4-hydroxy-2, 3-dimethoxyphenyl)-3-(4-hydroxyphenyl) propene (5), (Z)-1-(3-hydroxy-2, 4-dimethoxy-phenyl)-3-(4-hydroxy-3-methoxy-phenyl) propene (6), methylprotocatechuate (7), katuranin (8).
CONCLUSIONS:
Among these compounds, compound 6 was isolated from D. blandum for the first time. In the MTT test, compounds 2 and 6 exhibit cytotoxic activities against the KB cell, and compounds 3 and 6 exhibit the same activities against the HepG2 cell.

Chemical constituents against hepatic fibrosis from Phyllodium pulchellum roots.[Pubmed:
25174106]
To investigate the bioactive constituents against hepatic fibrosis from the roots of Phyllodium pulchellum.
METHODS AND RESULTS:
The chemical constituents of Phyllodium pulchellum roots were obtained by various chromatographic technologies and identified by several spectroscopic methods.
Ten compounds were elucidated as 3,5,2',4'-tetrahydroxy-2",2"-dimethylpyrano-[5",6",7,8] -flavanone (1), Yukovanol (2), citflavanone (3), 8-prenylated 5,7,3',4'-tetrahydroxyflavanone (4), pulchelstyrene A (5), pulchelstyrene B (6), pulchelstyrene D (7), 3-indolcarbaldehyde (8), 3-methoxyindole (9) and p-hydroxybenzoic acid (10). The effects to inhibit the proliferation of activated HSC-T6 cells of all isolated compounds were also evaluated.
CONCLUSIONS:
All compounds are isolated from this plant for the first time except for compounds 5 - 7. Compounds 2,4,5 and 6 can inhibit the proliferation of activated HSC-T6 cells in vitro.
