“…The MS and NMR spectra of compounds 1-3 were in complete agreement with the literature data of stylopine, corydaline, and dehydrocorydaline ( Fig. 1), respectively [15][16][17][18][19][20]. The C NMR spectra are summarized in Table S1.…”

“…Methanol or ethanol often with addition of water (Bugatti et al, 1987 ; Han et al, 1991 ; Koriem et al, 2013 ) and hydrochloric (Kursinszki et al, 2006 ; Gu et al, 2010 ) or acetic acid (Paulsen et al, 2015 ) were used as extractants. The isolation from plant material was also achieved with the use of pure acidified water; further, the solution was alkalized with ammonia or sodium hydroxide to obtain base forms followed by liquid-liquid extraction with organic solvents such as dichloromethane, butanol or chloroform (Sārközi et al, 2006 ; Sárközi et al, 2007 ; Migas et al, 2012 ; Jesionek et al, 2016 ; Bogucka-Kocka and Zalewski, 2017 ). The isolation was conducted by percolation (Capistrano et al, 2015 ), maceration (Koriem et al, 2013 ; Borghini et al, 2015 ), heating under reflux (Gu et al, 2010 ; Yao et al, 2011 ; Seidler-Łozykowska et al, 2016 ), in water bath (Sārközi et al, 2006 ) or Soxhlet apparatus (Bugatti et al, 1987 ; Stuppner and Ganzera, 1995 ) as well as ultrasound assisted (UAE) (Kursinszki et al, 2006 ; Sárközi et al, 2007 ; Paulsen et al, 2015 ; Jesionek et al, 2016 ) or microwave energy (MAE) (Then et al, 2000 ; Zhou et al, 2012 ).…”

“…Silica was the most common stationary phase, often impregnated with salts (Ni, Zn, Cr, Co) to improve the selectivity (Wagner et al, 1984 ; Then et al, 2000 ; Waksmundzka-Hajnos et al, 2000 ; Sārközi et al, 2006 ; Sárközi et al, 2007 ; Petruczynik et al, 2008 ; Jesionek et al, 2016 ) Silica modified with octadecyl (C-18) and cyanopropyl (CN) groups and aqueous solutions of methanol or isopropanol with ammonia or diethylamine which prevented tailing of chromatographic bands were sporadically applied (Petruczynik et al, 2007 ). Petruczynik et al ( 2008 ) combined various types of stationary phases e.g., cyanopropyl silica with silica or octadecyl silica to obtain adsorbent gradient.…”

“…Because of the broad spectrum of action, C. majus alkaloids are a subject of interest for pharmacology and toxicology; therefore, the effective analytical methods for their investigation are still being developed. Spectrophotometry [ 5 , 6 ], capillary electrophoresis [ 7 , 8 ], and thin-layer chromatography [ 9 12 ] have been used for this purpose; however, high-performance liquid chromatography is the most common for qualitative and quantitative analyses of C. majus [ 5 , 13 17 ].…”
