|Source:||The herbs of Salvia plebeia R.Br.|
|Biological Activity or Inhibitors:||1. Nepetin-7-glucoside has antioxidant activity in human HL60 cells assessed as reduction of cytochrome-c release, DPPH free radical scavenging activity, and inhibition of TPA-induced free radical formation.
|Solvent:||Pyridine, Methanol, Ethanol, 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. 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.

|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.|

|Chemical fingerprint and quantitative analysis of Salvia plebeia R.Br. by high-performance liquid chromatography.[Pubmed: 18678457]|
|To control the quality of Salvia plebeia R.Br., a simple and reliable method of high-performance liquid chromatography coupled with photodiode array detector (HPLC-DAD) was developed both for fingerprint analysis and quantitative determination of seven bioactive compounds, namely caffeic acid, luteolin-7-glucoside, Nepetin-7-glucoside, homoplantaginin, luteolin, nepetin and hispidulin. In fingerprint analysis, twelve peaks were selected as characteristic peaks. In quantitative analysis, seven compounds showed good regression (R2>0.9995) within test ranges and the recovery of the method was in the range of 91.7-103.2%. The content ranges (mg/g) of seven compounds in the collected samples of S. plebeia were 0.80-1.67 (hispidulin), 2.18-5.75 (homoplantaginin), 0.52-1.22 (nepetin), 1.56-3.48 (Nepetin-7-glucoside), 0.12-0.24 (luteolin), 0.97-2.22 (luteolin-7-glucoside) and 0.21-0.44 (caffeic acid), respectively. From the results obtained, the content of homoplantaginin was the highest. In addition, luteolin and luteolin-7-glucoside were isolated for the first time from S. plebeia.|
