| Description: |
Przewalskinic acid A is a rare, water-soluble, and highly biologically active ingredient found, thus far, only in the Salvia przewalskii Maxim herb. |
Przewalskinic acid A Description
| Source: |
The roots of Salvia miltiorrhiza Bge. |
| 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. 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. |

| Structure Identification: |
| J Ind Microbiol Biotechnol. 2014 May;41(5):887-92. | | Preparation of przewalskinic acid A from salvianolic acid B using a crude enzyme from an Aspergillus oryzae strain.[Pubmed: 24615145 ] | Przewalskinic acid A is a rare, water-soluble, and highly biologically active ingredient found, thus far, only in the Salvia przewalskii Maxim herb; however, the content in S. przewalskii herb is very low.
METHODS AND RESULTS:
In order to obtain useful quantities of Przewalskinic acid A, the biotransformatin of salvianolic acid B from Salvia miltiorrhiza root (danshen in Chinese) into Przewalskinic acid A was studied using a crude enzyme produced from Aspergillus oryzae D30s strain. The crude enzyme from the A. oryzae strain hydrolyzed salvianolic acid B into Przewalskinic acid A and danshensu. The preparation afforded 31.3 g Przewalskinic acid A (91.0 % purity) and 13.1 g danshensu (95 % purity) from 75 g salvianolic acid B. The preparation of Przewalskinic acid A was therefore very successful with a yield of over 86 %, but the yield of danshensu was only 33 %.
CONCLUSIONS:
The product Przewalskinic acid A was identified using ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) and NMR. |
