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.

Antiviral Matrine-Type Alkaloids from the Rhizomes of Sophora tonkinensis.[Pubmed:
26132528]
CONCLUSIONS:
Three new matrine-type alkaloids, (+)-5α-hydroxyoxysophocarpine (1), (-)-12β-hydroxyoxysophocarpine (2), and (+)-5α-hydroxylemannine (3), along with 14 known analogues, (-)-sophocarpine (4), (-)-5α-hydroxysophocarpine (5), (-)-9α-hydroxysophocarpine (6), (+)-12α-hydroxysophocarpine (7), (-)-12β-hydroxysophocarpine (8), (+)-oxysophocarpine (9), (+)-matrine (10), (+)-Sophoranol (11), (+)-9α-hydroxymatrine (12), (-)-14β-hydroxymatrine (13), (+)-oxymatrine (14), (+)-5α-hydroxyoxymatrine (15), (-)-14β-hydroxyoxymatrine (16), and (+)-sophoramine (17), were isolated from the rhizomes of Sophora tonkinensis. Their structures were elucidated via spectrometric data analyses, and the absolute configurations were established by single-crystal X-ray diffraction and ECD data.
CONCLUSIONS:
Alkaloids 2, 6, 11, and 13 exhibited antiviral activity against the Coxsackie virus B3 (CVB3), with IC50 values of 26.62-252.18 μM, and alkaloids 7, 8, and 17 inhibited influenza virus A/Hanfang/359/95 (H3N2) replication with IC50 values of 63.07-242.46 μM.

Quinolizidine alkaloids with anti-HBV activity from Sophora tonkinensis.[Pubmed:
16783704 ]
METHODS AND RESULTS:
A new matrine-type alkaloid, (-)-14 beta-hydroxyoxymatrine (1), was isolated from the roots and rhizomes of Sophora tonkinensis Gapnep. (Leguminosae), together with five known matrine-type alkaloids, (-)-14 beta-hydroxymatrine (2), (+)-oxymatrine (3), (+)-matrine (4), (+)-Sophoranol (5), and (-)-5 alpha-hydroxysophocarpine ( 6), as well as with two known cytisine-type alkaloids, (-)-cytisine (7) and (-)- N-methylcytisine (8). Their structures were elucidated by spectroscopic methods.
CONCLUSIONS:
Compounds 1, 5 and 7 showed potent anti-HBV activity with an inhibitory potency against HBsAg secretion of 22.6 %, 31.1 % and 33.2 %, and against HBeAg secretion of 30.4 %, 26.3 % and 27.8 %, respectively.
