Identification
Morphology
Spirodela polyrhiza is a diminutive herb that maintains a self-supporting growth form. This tiny aquatic plant is characterized by its extremely small stature, reaching a maximum height of only 0.008 m. Even at its absolute peak, the height of the species does not exceed 0.01 m. Such minimal dimensions allow it to thrive effectively within its specific ecological niche.

Biological Activities
Spirodela polyrhiza contains a unique protease that demonstrates significant medicinal potential. Research indicates that this plant possesses both fibrinolytic and antithrombotic activities. The purified enzyme is capable of hydrolyzing fibrinogen by specifically cleaving its Aalpha and Bbeta chains. Furthermore, its anticoagulating properties were confirmed through the measurable delay of APTT, TT, and PT test times. These findings suggest that the bioactive components of the plant could play a vital role in managing blood clotting processes.
Compounds
Conditions
Spirodela polyrhiza contains a purified protease that demonstrates significant fibrinolytic activity by hydrolyzing both fibrin and fibrinogen. This enzyme exhibits measurable anticoagulating activity through its ability to delay clotting processes. Specifically, the plant's protease acts upon activated partial thromboplastin time (APTT) by delaying the results. It also impacts prothrombin time (PT) by extending the duration of these tests. Through these biochemical mechanisms, the plant effectively interacts with key components of the coagulation cascade.
