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.

Chemical constituents of the leaves of Menispermum dauricum

Chemistry of Natural Compounds, 2013
Menispermum dauricum is widely distributed in the Peoples Republic of China. The rhizomes of the plant, known in traditional Chinese medicine as Bei-Dou-Gen, are officially listed in the Chinese Pharmacopoeia and used for treating sore throat, colitis, dysentery, and rheumatic arthralgia [1].

Cytotoxic Oxoisoaporphine Alkaloids from Menispermum dauricum

Journal of Natural Products, 2001
Four new oxoisoaporphine alkaloids, daurioxoisoporphines A-D (1-4), were isolated from the rhizomes of Menispermum dauricum. The structures of these alkaloids were established by spectroscopic methods. The cytotoxic evaluation of 1 and 2 is reported against four cancer cell lines.

(+)-Strigol, a witchweed seed germination stimulant, from Menispermum dauricum root culture

Phytochemistry, 2003
(+)-Strigol was isolated from Menispermum dauricum root culture filtrate. Its identity was confirmed by HPLC, 1H NMR, UV and MS, and on the basis of its CD spectrum. This is the first report on isolation of strigolactone from aseptic plant culture.

Early Steps of Dauricine Biosynthesis in Cultured Roots ofMenispermum dauricum

Bioscience, Biotechnology, and Biochemistry, 1996
Cultured roots of Menispermum dauricum, a rich source of the bisbenzylisoquinoline alkaloid dauricine (1), were fed with l-[U-(14)C] tyrosine, L-[3-(13)C] tyrosine, and [2-(13)C] tvramine independently, and the incorporation of possible early precursors into 1 was studied.

Rare oxoisoaporphine alkaloids from Menispermum dauricum with potential anti-inflammatory activity

Phytochemistry
Eleven alkaloids including four previously undescribed oxoisoaporphine alkaloids, menisoxoisoaporphines A-D (1-4), four known analogues (5-8), and three aporphine alkaloids (9-11), were isolated and identified from the rhizomes of Menispermum dauricum. Their structures were elucidated by extensive spectroscopic data and single-crystal X-ray diffraction

[A new alkaloid of Menispermum dauricum DC--dauriciline].

Yao xue xue bao = Acta pharmaceutica Sinica, 1992
A new phenolic dauricine-type alkaloid, named "dauriciline", was isolated from the rhizome of Menispermum dauricum DC. It is a pale yellow powder. Based on spectrometric analysis (UV.FAB-MS and 1HNMR) and chemical reaction the structure of the new alkaloid was elucidated as RR,7,7'-demethyldauricine (VI).
