Analyzing thç alkaloids
triggered
Discovery of reserpine in the root of the Indian plant, Rauwolfia serpentina, has the search for similar alkaloids. Reserpine crystals shown magnified hundreds of times.

Automatic Recording Spectrophotometer a n a l y z e s f r a c t i o n s 12 t i m e s f a s t e r O n e of the most exciting stories in pharmaceutical research today is the search for biologically active alkaloids similar to reserpine—the remarkable tranquilizing drug extracted from the root of a plant. Using leaves, flowers, and roots from every part of the world, r e s e a r c h e r s collect e x t r a c t s , s e p a r a t e them chromatographically, and test the fractions on animals. When an active fraction is found, a spectral curve is run on an automatic recording spectrophotometer, as an aid in determining the structural formula. DK cuts analysis to S minutes per run
More time for more progress in research...
with the Beckman DK-2 Recording Spectrophotometer
Previously, with manual instruments, plotting each curve took an hour or more. With the Beckman automatic recording DK, however, the complete curve is traced in 5 minutes —adding many productive hours to the researcher's day, and speeding the discovery of useful new drugs. Where many measurements are needed in the ultraviolet— as in quality control of steroids—the DK makes other dramatic savings in time. And near-infrared analysis — also available with the DK—is proving of great value. To discover how a Beckman DK can help break through your "time barrier"—in advanced research or in quality control — ask your Beckman dealer for a demonstration, or write for Data File L-30-15.
