General tips:For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging:1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition:Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

In vivo

Absorption and pharmacokinetics of radix rehmanniae in rats.[Pubmed: 24358782]

Yao Xue Xue Bao. 2013 Sep;48(9):1464-70.

In this paper, absorption and pharmacokinetic study of Radix Rehmanniae was studied by liquid chromatography coupled with mass spectrometry method after oral administration to rats.
METHODS AND RESULTS:
By comparing the chromatograms of ultraviolet, full scan, extracted ion and selective reaction monitoring (SRM) of standard solution, Radix Rehmanniae, blank plasma and rat plasma post drug administration, catalpol and ajugol were found to be the main compounds absorbed from Radix Rehmanniae. Plasma concentrations of aucubin, dihydrocatalpol, Rehmannioside A (or rehmannioside B/ melittoside) and rehmannioside D were very low. Quantitative method for catalpol and aucubin and semi-quantitative method for other compounds in rat plasma were established. The pharmacokinetic study of those absorbed components was conducted after oral administration of 6 g x kg(-1) Radix Rehmanniae water extract to rats.
CONCLUSIONS:
Cmax, t(1/2) and AUC(0-infinity) of catalpol and ajugol were (2349.05 +/- 1438.34) and (104.25 +/- 82.05) ng x mL(-1), (0.86 +/- 0.32) and (0.96 +/- 0.37) h, (4407.58 +/- 2734.89) and (226.66 +/- 188.38) ng x h x mL(-1), respectively. tmax was at 1.00 h for catalpol and ajugol. Both catalpol and ajugol were absorbed and excreted rapidly.

Isolation and identification of the chemical constituents from Rehmannia glutinosa L.[Reference: WebLink]

To study the chemical constituents from Rehmannia glutinosa.
METHODS AND RESULTS:
Compounds were isolated by chromatography on silica gel,Sephadex LH-20 and PHPLC.Their structures were confirmed on the basis of physico-chemical constants and spectroscopic analysis.Ten compounds were isolated and their structures were identified as 7-isoquinolinol(1),5-hydroxy-2-pyridinemethanol(2),6-methyl-3-pyridinol(3),salidroside(4),rehmanniosid C(5),Rehmannioside A(6),adenosine(7),adenine(8),uridine(9)and β-sitosterol(10),respectively.
CONCLUSIONS:
Compounds 1-4 are isolated from Rehmannia genus for the first time.
