Identification
Biological Activities
Lotus (Nelumbo nucifera) is a versatile aquatic plant recognized for its significant medicinal and nutritional value across various traditional medicine systems. Research highlights its potent antidiabetic properties, particularly through the use of rhizome extracts containing asteroidal triterpenoids. The plant also exhibits strong antioxidant activity due to the complex biosynthesis of phenolic compounds within its rhizome. Furthermore, studies on the alkaloid neferine demonstrate a promising antitumor effect by inhibiting cell proliferation and inducing apoptosis in experimental models. Beyond these specific functions, the whole plant has traditionally been utilized for its astringent and diuretic capabilities to treat various inflammatory and homeostatic conditions.
Compounds
Lotus plants are rich in diverse bioactive compounds that contribute to their significant medicinal and nutritional value. These plants contain flavonoids and various alkaloids, which play a crucial role in their pharmacological effects. Specifically, the lotus contains nuciferine and neferine, two major alkaloids known for their potential therapeutic benefits in treating metabolic and inflammatory conditions. Furthermore, the presence of bisbenzylisoquinolines underscores the complex chemical profile found within different parts of the plant. Finally, research into species like Lotus corniculatus highlights that lotus also contains PAS, or proanthocyanidins, which are regulated by specific genetic pathways.
Conditions
Preparations
Lotus is prepared as leaf black tea through a fermentation process to enhance its functional components and antioxidant activity. The plant is also prepared as lotus-derived EVs (LDEVs) through various isolation methods to explore their potential in modulating inflammation and wound healing.
