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.

Simultaneous determination of 4 alkaloids and a flavonoid in Picrasmae Ramulus et Folium by RP-HPLC.[Pubmed: 25095379]

METHODS AND RESULTS:
A RP-HPLC method was developed to evaluate the quality of Picrasmae Ramulus et Folium by simultaneous determination of five constituents including 1-hydroxymethyl-beta-carboline (1), 1-methoxicabony-beta-carboline (2), 4-methoxy-5-hydroxy-canthin-6-one (3), 4, 5-dimethoxy-canthin-6-one (4) and maackiain (5) in Picrasmae Ramulus et Folium. The samples were separated on a Kromasil RP-C18 (4.6 mm x 250 mm, 5 microm) column eluted with acetonitrile and 0.1% phosphoric acid as mobile phases in gradient mode. The detection wavelength was set at 254 nm. The calibration curves and linearity of the above five standards were determined as (1) Y = 6 525.6X + 37.25 (0.009-1.780 microg, r = 0.996 8), (2) Y = 3 662.3X + 41.55 (0.005-0.920 microg, r = 0.999 5), (3) Y = 3763.1X + 146.87 (0.015-3.060 microg, r = 0.999 0), (4) Y = 2 174.1X + 21.52 (0.003-0.620 microg, r = 0.999 5), and (5) Y = 276.25X + 7.65 (0.010-1.960 microg, r = 0.998 9), respectively.
CONCLUSIONS:
The method is simple and repeatable, and can be used for the quality assessment of Picrasmae Ramulus et Folium.
