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.

Pharmacokinetics, bioavailability, and metabolism of Notoginsenoside Fc in rats by liquid chromatography/electrospray ionization tandem mass spectrometry.[Pubmed: 25770412
Notoginsenoside Fc (NGFc) is a protopanaxadiol-type (PPD-type) saponin from Panax notoginseng, which has perfect anti-platelet aggregatory effect. However, its pharmacokinetics and metabolism in vivo remain unknown.
METHODS AND RESULTS:
In this study, a simple and sensitive liquid chromatography/electrospray ionization tandem mass spectrometry (LC-MS/MS) method was first developed for the determination of NGFc in rat plasma. After methanol-mediated protein precipitation, separation was achieved on a C18 column with MS detection operated in negative SRM mode at m/z 604.56→m/z 783.90 and m/z 799.93→m/z 637.64 for NGFc and IS, respectively. The assay was linear over the concentration range (r>0.995) with the LLOQ of 0.002μg/ml. The intra- and inter-day precisions (R.S.D.) were 2.45-12.36% and 3.67-14.22%, respectively; whereas accuracy ranged from (R.R.) 93.90% to 99.41%. The extraction recovery, stability, and matrix effect were within the acceptable limits.
The validated LC-MS/MS method was successfully applied to the pre-clinical pharmacokinetic studies of NGFc in rat. After oral and intravenous administration, NGFc showed dose-independent pharmacokinetic behaviors with a t1/2 of >22h and its oral bioavailability was 0.10-0.14%. In addition, a total of 10 metabolites were detected and structurally characterized by UPLC-Q/TOF-MS technique, which suggested that deglycosylation was the major metabolic pathway for NGFc in rats.

Saponins in the fruit pedicels of Panax notoginseng (Burk.) F.H. Chen (continue).[Pubmed: 1294178
Six saponins were isolated from the fruit pedicels of Panax notoginseng.
METHODS AND RESULTS:
Five of them were identified as gypenoside-XVII, -XV, ginsenoside-Rb1, and notoginsenoside-Fc, -Fa on the basis of chemical methods, spectroscopic analysis and comparison with authentic standards.
Quantitative determination of the major saponins in fruit pedicels from the plant was made by thin layer chromatography-densitometry.
