Dechlorodauricumine from cultured roots of Menispermum dauricum

Phytochemistry, 2005
Dechlorodauricumine, a possible organic substrate for biochlorination, was isolated from cultured roots of Menispermum dauricum, a rich source of chlorinated alkaloids. Its structure was established by spectroscopic and chemical methods.

Chemical constituents of Menispermum dauricum

Chinese Journal of Natural Medicines, 2012
Abstract Aim To study the chemical constituents of Menispermum dauricum DC. Methods Compounds were isolated by repeated chromatography on silica gel and Sephadex LH-20. The structures were identified by spectral analysis and comparison with literature data.

Isoquinoline and isoindole alkaloids from Menispermum dauricum

Phytochemistry, 2004
Three 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 ...

Acutudaurin from Cultured Roots of Menispermum dauricum

Planta Medica, 2001
A 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 ...

Menispermum dauricum DC.

1992
Beiduogen, Rhizoma Menispermi, is the dry rootstock of Menispermum dauricum DC. (Menispermaceae), which occurs widely in China. It is a traditional Chinese medicine and is now officially listed in the Chinese Pharmacopoeia. Beiduogen Pian, Tabellae Menispermi, is another official item produced from the total alkaloidal extract of M. dauricum.

Chlorinated Alkaloids in Menispermum dauricum DC. Root Culture

The Journal of Organic Chemistry, 2001
Feeding experiments using (36)Cl showed that Menispermum dauricum root culture produces four alkaloids containing chlorine. They included the novel alkaloids dauricumine and dauricumidine as well as the known alkaloids acutumine and acutumidine. The structures of novel alkaloids were established by spectroscopic, crystallographic, and chemical methods.
