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 ...

Dauricine production in cultured roots of Menispermum dauricum

Phytochemistry, 1994
Abstract Root Cultures of Menispermum dauricum were established from adventitious roots formed on the leaf segments. These roots produce dauricine as a major constituent and the optimum conditions for dauricine production in cultured roots were investigated.
