Astrasieversianin VII Description
||The roots of Astragalus membranaceus (Fisch.) Bunge
||DMSO, Pyridine, Methanol, Ethanol, etc.
||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.
Need more advice on solubility, usage and handling? Please email to: firstname.lastname@example.org
||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.

|An isoflavan and saponins from Astragalus depressus L.[Reference: WebLink]|
| In this study, nine known secondary metabolites were isolated from ethyl acetate and n-butanol extracts of Astragalus depressus L. (Fabaceae family), including one isoflavan, namely pendulone (1) and eight saponins, namely cyclogaleginoside A (2), astrasieversianin II (3), astrasieversianin IV (4), Astrasieversianin VII (5), astrasieversianin VI (6), astrasieversianin XIV (7), dehydrosoyasaponin I (8) and soyasaponin I (9). The structures of compounds 1-9 were elucidated by using spectroscopic methods, including 1D and 2D NMR, ESI mass spectrometry and comparison with literature data.
