Two similar pathways have been reported (79) for the total synthesis of a pseudobenzylisoquinoline-type alkaloid, rugosinone (43), isolated as a minor component of Thalictrum rugosum. As shown in Scheme 8 the anion of N-benzoyl-l-cyano-6,7-methylenedioxy-l,2-dihydroisoquinoline (28) was reacted... [Pg.6]

Another alkaloid of Thalictrum rugosum is thaligosinine (313), 38 42 2 7 > colorless crystals, mp 233-234.5°C (dec.) (ether), [a] 1 —58.5° (c 0.316, MeOH), HRMS m/e 638.3005. Diazomethane converted 313 to thalrugosami-nine (309, Section II,C, 134), a known alkaloid of T. rugosum. The complete structure of thaligosinine was apparent from the mass spectrum, m/e 426 (15%, cleavage at a), which showed that the sole phenolic function is in the lower portion of the molecule (146). [Pg.85]

Protopine, cryptopine, and allocryptopine have been isolated from Papaver rupifragum,75 protopine and allocryptopine from Glaucium vitellinum,109 Corydalis ophiocarpa,71 and C. cava,70 and protopine from Nandina domestica110 and Thalictrum rugosum,12... [Pg.95]

Until now, bioreactors of various types have been developed. These include loop-fluidized bed [14], spin filter, continuously stirred turbine, hollow fiber, stirred tank, airlift, rotating drum, and photo bioreactors [1]. Bioreactor modifications include the substitution of a marine impeller in place of a flat-bladed turbine, and the use of a single, large, flat paddle or blade, and a newly designed membrane stirrer for bubble-free aeration [13, 15-18]. Kim et al. [19] developed a hybrid reactor with a cell-lift impeller and a sintered stainless steel sparger for Thalictrum rugosum cell cultures, and cell densities of up to 31 g L1 were obtained by perfusion without any problems with mixing or loss of cell viability the specific berberine productivity was comparable to that in shake flasks. Su and Humphrey [20] conducted a perfusion cultivation in a stirred tank bio-... [Pg.4]

The selectivity of the target product to undesired product by encapsulated XAD-7 was examined by the competitive adsorption of berberine and dopamine produced in Thalictrum rugosum culture [18]. To investigate the degree of separation, the separation factor, a, was considered ... [Pg.74]

As trial system to test the application of the proposed model the ability of encapsulated XAD-7 was evaluated for the selective separation of berberine from dilute aqueous mixtures of berberine and dopamine, the target secondary metabolite, and an undesirable intermediate metabolite of Thalictrum rugosum plant cell culture [18]. Competitive adsorption experiments were performed in dilute aqueous mixtures of berberine and dopamine, both at initial concentrations of 60 mg l-1, which is representative of actual plant cell culture. Experimental and theoretical results for normalized bulk concentration profiles of berberine and dopamine are shown in Fig. 10. The bulk berberine concentration was reduced to approximately 4.6% of the initial concentration, which indicates that 95.4% of the berberine in the initial mixed solution was adsorbed. Encapsulated XAD-7, therefore, selectively concentrated the berberine from dilute aqueous mixtures of berberine and dopamine. [Pg.85]

A new alkaloid, protothalipine (142 R = H), isolated from Thalictrum rugosum, gives muramine (142 R = Me) upon O-methylation. The location of the phenolic hydroxy-group was deduced with the aid of ASIS studies. [Pg.139]

The known phenanthrene alkaloid thaligludnone has been found in Thalictrum rugosum, and it exhibits antimicrobial activity against Microbacterium smegmatis. The presence of a methylenedioxy-group at C-3,4 in a phenanthrene alkaloid results in the H n.m.r. spectrum showing an upheld shift of the C-5 proton. ... [Pg.165]
