The derivatives are concrete and absolute. The concrete is prepared
in approximately 1.5 to 2.0% yields by solvent extraction (ben zene, petroleum ether) of the freshly cut flowering herb. It is a
dark-green, viscous mass. An absolute is obtained in approxi mately 45% yields by distillation of the concrete with diethylene
glycol.
