The leaves contain contractile proteins similar to myosin. The oil content of the seed is about 17%, which is similar to soybean oil. The fatty acids in the oil are linolenic acid 0.4%, turbidity acid 51%, oleic acid 31%, stearic acid 8.7% and stearic acid 8.9%, and the unsaponifiable substance 2.5%, mainly sterols.

[pharmacological action] plants containing Mimosa alkaloids can cause hair loss when eaten by animals such as horses and donkeys. Mimosamine can be regarded as a toxic amino acid, and its structure is similar to tyrosine. Its toxic effect is due to inhibiting the enzyme system using tyrosine, or replacing the position of tyrosine in some important proteins. When the feed contains 0.5-1.0% Mimosa alkali, the growth of rats or mice will stop, hair loss and cataract. When people eat plants containing this alkaloid, their hair may suddenly fall off. It can slightly inhibit alkaline phosphatase, but not metal containing enzyme system. Its low iron complex is far less toxic. Tyrosine can antagonize the inhibitory effect of Mimosa on the growth of rats.
