摘要：
Oxindole alkaloids are the main constituents of Uncaria tomentosa (Willd.) DC and are regarded as marker compounds of this plant. A trichloroethylene extract of crushed bark from Uncaria tomentosa was chromatographed by TLC on unmodified silica gel and on silica gel chemically modified with polar and non-polar groups to determine the best separation of the alkaloids present in the extract.
