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.

Production of lignans in calluses of Schisandra chinensis.[Pubmed:
21927855]
METHODS AND RESULTS:
Chloroform extracts of all induced calluses contained gomisin A and Gomisin F as major components. Gomisin A and Gomisin F contents of calluses that were cultured under the optimal conditions mentioned above were highest compared to the calluses incubated with other combinations of plant hormones and media. Subculture, by repeated transfer of cultured calluses to fresh medium, caused no decrease in the production of gomisin A and Gomisin F. Optimal conditions for lignan production were found to be 1/2 MS medium supplemented with 0.05 mg/1 Kin and 0.2 mg/l 2,4-D.
CONCLUSIONS:
Under these conditions, gomisin A and Gomisin F contents were 0.05 and 0.04% of callus dry weight, respectively.
