|| Hupehenine is a natural product from Fritillaria thunbergii Miq.|
||The bulbus of Fritillaria thunbergii Miq.
||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, 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: email@example.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.

|Analysis of Hupehenine in the Total Alkaloids from Fritillaria hupehensis by HPLC-ELSD[Reference: WebLink]|
|A reverse-phase high pressure liquid chromatography (HPLC) method with evaporative light scattering detection (ELSD) has been developed for the quantitative analysis of Hupehenine in the total alkaloids from Fritillaria hupehensis.
METHODS AND RESULTS:
Samples were analyzed on a reverse-phase column (Hypersil C-18) with a mobile phase of methanol:water:chloroform: triethylamine (85:15:1:0.6). The ELSD was set at the drift tube temperature of 68.3℃ and gas flow rate of 1.8 L/min. Hupehenine's retention time was 13.7 min with an asymmetry factor of 1.2. The validity of the method has been verified with linearity, limit of detection, accuracy and precision. The logarithmic linear curve was obtained from 8.936 to 134.04 μg/mL (r=0.9993). The detection limit (S/N＞3) of Hupehenine was 1.79 μg/mL on the column. Intra-day RSD was 1.42% and inter-day RSD was 2.26% (3 days within a week). The average recovery of Hupehenine was 101.50%, and RSD was 1.62%.
