Source:	The herbs of Thesium chinese
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.

Structure Identification:

2007 IEEE/ICME International Conference on Complex Medical Engineering-CME2007

Isolation and Structure Elucidation of the Chemical Constituents from Thesium chinense Turcz[Reference: WebLink]

METHODS AND RESULTS:
Phytochemical investigation of Thesium chinense Turcz, led to the isolation of seven compounds from the ethyl acetate extract using column chromatography and preparative TLC. The structures of these compounds were identified as, kaempferol-3-O-beta-D-glucopyranosyl (1rarr2)-O-beta-D-6- acetlyglucopyranoside (I), Kaempferol 5-methyl ether (II), apigenin-5-O- [-L-Rhamnopyranosyl- (1rarr4)-beta-D-glucopyranoside] (III), kaempferol-3-O-glucoside (IV), apigenin-7-O-glucoside (V), kaempferol (VI) and 4'-hydroxy acetophenone (VII) using UV,1H-NMR,13C-NMR and ESI-MS analysis.
CONCLUSIONS:
Compounds I, II, III and VII were isolated from this plant for the first time.
