Acutudaurin from Cultured Roots of Menispermum dauricum
Planta Medica, 2001A new alkaloid, acutudaurin, was isolated from cultured roots of Menispermum dauricum, a rich source of the chlorine-containing alkaloid acutumine and its dechlorinated analogue dechloroacutumine. The structure of acutudaurin was determined to be 2',3'-dihydro-5-hydroxy-4,6',7'-trimethoxy- 1'-methylspiro[3-cyclohexene-1,10'-[3a,7a]propano[1H]indole]-2 ...

Isoquinoline and isoindole alkaloids from Menispermum dauricum
Phytochemistry, 2004Three isoquinoline alkaloids and an isoindole alkaloid, along with eight known compounds, were isolated from the roots of Menispermum dauricum (Menispermacese). The alkaloids were characterized as 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 and 6 ...

Biochemical Systematics and Ecology, 2020
Abstract The phytochemical investigations on the rhizome of Menispermum dauricum DC. led to the isolation of 18 compounds, including eleven alkaloids (1–11), four amides (12–15) and three fatty acids (16–18). All chemical structures were established on the basis of NMR (1H NMR and 13C NMR) spectroscopic data.

Oxoisoaporphines from Menispermum dauricum
Phytochemistry, 1999Two oxoisoaporphine alkaloids, 2,3-dihydrodauriporphine and tyraminoporphine, together with the known alkaloid dauriporphine, were isolated from Menispermum dauricum roots cultured in a medium containing ketoconazole, a cytochrome P-450 inhibitor. Structures of the alkaloids were established by spectroscopic, crystallographic and chemical methods.
