Atractyloside potassium salt | CAS:102130-43-8

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.

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.

Influence of Processing on the Content of Toxic Carboxyatractyloside and Atractyloside and the Microbiological Status of Xanthium sibiricum Fruits (Cang'erzi)[Pubmed: 26287695]

Abstract The dried ripe fruits of Xanthium sibiricum (Cang'erzi) are used in traditional Chinese medicine for the treatment of nasal congestion, nasal discharge, allergic rhinitis, sinusitis, and wind-cold headaches. Carboxyatractyloside and atractyloside are important constituents of the fruits because these diterpenoid glycosides are responsible for their toxicity. In order to evaluate procedures for reducing the amount of the more toxic carboxyatractyloside, the fruits were dried and heated with different methods. Carboxyatractyloside and atractyloside were analysed by a new reversed-phase high-performance liquid chromatographic method using liquid chromatography-diode array detector-tandem mass spectrometry analysis. The results revealed that temperature and drying methods have a strong influence on the content of carboxyatractyloside and atractyloside. Fruits which were treated at higher temperatures showed a lower content of carboxyatractyloside and an increased content of atractyloside, which is 50 times less toxic. This indicates that the roasting process can reduce toxicity effectively. The microbiological colonisation of Xanthium fruits is also reduced by roasting and by drying above 100 °C. For the safe use of Cang'erzi, the effect of processing should be monitored and analysis of carboxyatractyloside and atractyloside should be obligatory in quality control.
