Epi-Cryptoacetalide Description
Source: The roots of Salvia miltiorrhiza
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: 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.

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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Yao xue xue bao,2011, 46(7):818-821.
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.
