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.

Cytotoxic tirucallane triterpenes from the stem of Luvunga scandens.[Reference: WebLink
METHODS AND RESULTS:
Two tirucallane triterpenes, namely flindissol (1) and 3-Oxotirucalla-7,24-dien-21-oic acid (2), were isolated from the dichloromethane extract of the stem of Luvunga scandens (Roxb.) Buch-Ham ex Wight & Arn, Rutaceae. This is the first report of their isolation from this plant. Their structures were constructed by high resolution mass and 2D NMR spectroscopic data. The cytotoxic potential of the two pure compounds 1 and 3-Oxotirucalla-7,24-dien-21-oic acid were determined by MTT assay against human breast adenocarcinoma cell line (MCF-7).
Compounds 1 and 3-Oxotirucalla-7,24-dien-21-oic acid showed potent cytotoxicity against MCF-7 cell line with IC50 values of 13.8 μM and 27.5 μM, respectively. This result suggested their potential activity as antitumor agents.

Study on Chemical Constituents of Petroleum Ether Fraction from Rubus alceaefolius.[Pubmed: 26214876
To investigate the chemical constituents of Rubus alceaefolius.
METHODS AND RESULTS:
Nine compounds were isolated and purified from the petroleum ether extract of 95% alcohol extract of Rubus alceaefolius by repeated column chromatography on silica, Sephadex LH-20 and structurally identified by spectral analysis.
The compounds were identified as chrysophanol(1), physcion (2), β-sitosterol(3), 3-oxotirucalla-7, 24-dien-21-oic acid(4), myricadiol(5), 19-α-hydroxy-3-acetyl-ursolic acid(6), N-benzoylphenylalaninyl-N-benzoylphenylalaninate(7), aurantiamide acetate(8) and euscaphic acid(9).
Compounds land 4~8 are isolated from this plant for the first time, and compounds 4 - 8 are found in plants of Rubus genus for the first time.
