Description

“Pet poisonous” – Toxic parts: fruit, roots Menispermum dauricus is a plant of the family Menispermaceae . It is a climbing plantfrom Southeast Asia. It is known in traditional Chinese medicine as Bei-Dou-Gen. It is a vine that reaches 5 m. Its stems are woody at the base. The leaves are peltate, 3-5 lobed, rounded, gray-blue color. It is a cold-resistant plant. Its fruits have an endocarp in the shape of a horseshoe, surrounded on the contour with excavated faces .; presents a single dorsal ridge, a lateral ridge and a smooth surface with short spines on the dorsal and ventral edges; the dorsal aspect has two lateral concavities; there is also one final extremity more inward than the other; The condyle is double external, not perforated, making a large central area with a visible hollow near a limb. Length, 7.5 mm, width, 6.2 mm. The roots of Bei-Dou-Gen have been used in traditional Chinese medicine to treat sore throats, colitis, dysentery and rheumatic arthralgia . Several studies have shown the presence of different alkaloids belonging to several types of tetrahydroisoquinoline derivatives, such as bisbenzylisoquinolines, aporphins, proportions, protoberberines, and oxoisoaporphins. The latter have chemotaxonomic interest , because they seem to be exclusive to this species of plants, except lakshminina , which has been found in Sciadoternia toxifera . Have also been reported isoquinolines , benzylisoquinolines ,isoindoles and phenolic derivatives. Examples of compounds isolated from these plants are 7-hydroxy-6-methoxy-1 ( 2H ) -isoquinolinone, 6,7-dimethoxy- N- methyl-3,4-dioxo-1 (2H) -isoquinolinone, 1- ( 4-hydroxybenzoyl) -7-hydroxy-6-methoxy-isoquinoline, 6-hydroxy-5-methoxy- N- methylphthalimide, N- Demethyldorifornine, N- desmethyldorifornine , menisporfin , tiraminoporfin and daurioxoisoporphins .Menispermum dauricum was described by Augustin Pyrame de Candolle and published in Regni Vegetabilis Systema Naturale 1: 540. 1818 [1817]. Asian månfröranka ( Menispermum dauricum ) is a dicot plant species which was described by Dc .. According Catalog of Life Included Asian månfröranka the genus menispermum and family Menispermaceae , but according Dyntaxa, the affinity is instead genus menispermum and the Menispermaceae family . The species has not been found in Sweden. No subspecies are listed in the Catalog of Life.
