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: service@chemfaces.com
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.

Steroidal glycosides from the rhizomes of Anemarrhena asphodeloides and their antiplatelet aggregation activity.[Pubmed:
22307934]
METHODS AND RESULTS:
Five new steroidal glycosides, timosaponin J ( 1), timosaponin K ( 2), (25 S)-karatavioside C ( 5), timosaponin L ( 6), and (25 S)-officinalisnin-I ( 8), together with eight known steroidal saponins, timosaponin E (1) ( 3), purpureagitosid ( 4), timosaponin BII ( 7), timosaponin B III ( 9), Anemarrhenasaponin I ( 10), Anemarrhenasaponin III ( 11), anemarrhenasaponin A (2) ( 12), and timosaponin A III ( 13), were isolated from the rhizomes of Anemarrhena asphodeloides.
Their structures were elucidated on the basis of spectroscopic and chemical evidence.
CONCLUSIONS:
The aglycones of compounds 1 and 2 are new aglycones. Compounds 1- 13 were evaluated for their platelet aggregation activities, and compound 13 exhibited the strongest inhibitory effect on adenosine diphosphate (ADP)-induced platelet aggregation.

Effect of six steroidal saponins isolated from anemarrhenae rhizoma on platelet aggregation and hemolysis in human blood.[Pubmed:
10556655]
METHODS AND RESULTS:
Six steroidal saponins were isolated from Anemarrhena asphodeloides Bunge (Liliaceae), a traditional chinese medicine, and named Anemarrhenasaponin I (An-I), Anemarrhenasaponin Ia (An-Ia), timosaponin B-I (TB-I), timosaponin B-II (TB-II), timosaponin B-III (TB-III), and timosaponin A-III (TA-III). The effects of these six compounds on platelet aggregation and hemolysis in human blood were studied. All these compounds provoked remarkable inhibiting effect on platelet aggregation, and activated partial thromboplastin times (APTT) are sensitive to the presence of these six compounds. Using an in vitro system, APTT was delayed with the increment of the concentrations of these six compounds. In these six compounds, only timosaponin A-III appeared a strong effect on hemolysis, and Anemarrhenasaponin Ia had a slight effect on hemolysis, other had no effect on hemolysis.
CONCLUSIONS:
These results suggested that these steroidal saponins isolated from Anemarrhena asphodeloides Bunge (Liliaceae) might be used as a novel antithrombotic therapeutic agents in post-myocardial infarction.

Effects of different processing methods on five main chemical constituents of Anemarrhena asphodeloides Bge. studied by high performance liquid chromatography.[Pubmed:
23593885]
METHODS AND RESULTS:
A high performance liquid chromatographic (HPLC) method has been developed for the simultaneous determination of neomangiferin, mangiferin, timosaponin B III, Anemarrhenasaponin I and timosaponin A III in the products of Anemarrhena asphodeloides Bge. processed by different methods. By comparing and analyzing the variation of the contents of the five components, the effects of processing on chemical constituents of Anemarrhena asphodeloides Bge. were explored, which provided evidences for the relevance between processing and the property changes of Anemarrhena asphodeloides Bge. The chromatographic separation was performed on an Alltima C18 column (250 mm x 4.6 mm, 5 microm) with a gradient elution of acetonitrile (A) and 0. 1% formic acid (B) (0 - 10 min, 5% A - 20% A; 10 - 15 min, 20% A - 25% A; 15 -30 min, 25% A - 80% A; 30 -35 min, 80% A - 100% A) at a flow rate of 0.8 mL/min. Neomangiferin and mangiferin were detected by an ultraviolet detector at 265 nm and room temperature. Timosaponin B III, Anemarrhenasaponin I and timosaponin A III were detected by an evaporative light scattering detector with the drift temperature at 50 degrees C and gas pressure at 179.1 kPa (26 psi). To some extent, the contents of the major components varied in different processed products of Anemarrhena asphodeloides Bge.
CONCLUSIONS:
The results indicated that different processing methods caused significant differences in the contents of the major components of Anemarrhena asphodeloides Bge. It is of great use for further researching the relevance of the processing methods to pharmacodynamics of Anemarrhena asphodeloides Bge.

Steroidal saponins from Anemarrhena asphodeloides and their effects on superoxide generation.[Pubmed:
10617410]
METHODS AND RESULTS:
A new steroidal saponin, timosaponin F, along with six known compounds was isolated from the rhizomes of Anemarrhena asphodeloides Bge. On the basis of chemical and spectroscopic evidence, the structure of timosaponin F was elucidated as (5beta, 25 S):-spirostan-3beta,15alpha,23alpha-triol-3-O-beta- glucopyranosyl-(1--->2)-beta-galactopyranoside.
CONCLUSIONS:
The six known compounds were Anemarrhenasaponin I, Anemarrhenasaponin Ia, timosaponin BI, timosaponin BII, timosaponin B, timosaponin AIII; their effects on superoxide generation are also reported.
