It can be found in roots, rhizomes, stems, barks, or seeds of many herbal plants such as Caulophyllum thalictroides (blue cohosh), Arisolochai bracteate, P. amurense, S. acutum, Tinospora crispa, Coptidis rhizome, etc. Magnoflorine constitutes approximately 65 % of the total alkaloids in roots and rhizomes of blue cohosh. It is also known as thalictrine and escholine.

Magnoflorin has been used to test its contractile effects on isolated mouse uterine smooth muscle tissues and on isolated strips of Mus musculus distal colon smooth muscle tissues.

Magnoflorine possesses several biochemical and pharmacological properties such as antioxidant, anti-inflammatory, immunomodulatory, anti-diabetic, anti-fungal, cardiovascular protective, and neuropsychological. It also acts as an α-tyrosinase inhibitor. It helps to increase pro-inflammatory responses induced by lipopolysaccharide (LPS). It exerts antitumor, anti-cancer activities by inhibiting gastric cancer progression gastric cancer cell xenograft mouse model.
