The plant Buxus sempervirens has been well investigated chemically. During late 1980s, Dildar Ahmed while working on his PhD thesis under the supervision of Prof Atta-ur-Rahman, isolated a number of steroidal alkaloids from the leaves of the plant. A new system of nomenclature for buxus alkaloids was also proposed based on buxane nucleus. He also isolated a flavonoid glycoside, and named it galactobuxin based on the fact that it contains a galactose ring.
