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.

Novel steroidal saponins from Liriope graminifolia (Linn.) Baker with anti-tumor activities.[Pubmed:
21163470 ]
Phytochemical investigation of the underground parts of Liriope graminifolia (Linn.) Baker resulted in the isolation of two new steroidal saponins lirigramosides A (1) and B (2) along with four known compounds.
METHODS AND RESULTS:
The structures were determined by extensive spectral analysis, including two-dimensional (2D) NMR spectroscopy and chemical methods, to be 3-O-[β-d-xylopyranosyl-(1→3)-α-l-arabinopyranosyl-(1→2)-[α-l-rhamnopyranosyl-(1→4)]-β-d-glucopyranosyl-(25S)-spirost-5-ene-3β,17α-diol (1), 1-O-[α-l-rhamnopyranosyl-(1→2)-β-d-xylopyranosyl]-(25R)-ruscogenin (2), 1-O-β-d-xylopyranosyl-3-O-α-l-rhamnopyranosyl-(25S)-ruscogenin (3), 3-O-α-l-rhamnopyranosyl-1-O-sulfo-(25S)-ruscogenin (4), methylOphiopogonanone B (5), and 5,7-dihydroxy-3-(4-methoxybenzyl)-6-methyl-chroman-4-one, (Ophiopogonanone B, 6), respectively. Compound 1 has a new (25S)-spirost-5-ene-3β,17α-diol ((25S)-pennogenin) aglycone moiety.
CONCLUSIONS:
The isolated compounds were evaluated for their cytotoxic activities against Hela and SMMC-7721 cells.
