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 Salvia przewalskii Maxim.[Reference:
WebLink]
The investigation on Salvia przewalskii Maxim was carried out to find the relationship of the constituents and their pharmacological activities.
METHODS AND RESULTS:
The isolation and purification were performed by various chromatographies such as silica gel,Sephadex LH-20,RP-C18 column chromatography,etc.Further investigation on the fraction of the 95% ethanol extract of Salvia przewalskii Maxim yielded przewalskin Y-1(1),anhydride of tanshinone-ⅡA(2),sugiol(3),
Epi-Cryptoacetalide(4),cryptoacetalide(5),arucadiol(6),1-dehydromiltirone(7),miltirone(8),cryptotanshinone(9),tanshinone ⅡA(10) and isotanshinone-Ⅰ(11).Their structures were elucidated by the spectral analysis such as NMR(Nuclear Magnetic Resonance) and MS(Mass Spectrometry).
CONCLUSIONS:
Compound 1 is a new compound.Compounds 4 and 5 are mirror isomers(1∶3).Compounds 4,5,6,8,11 were isolated from Salvia przewalskii Maxim for the first time.
