Studies on the chemical constituents from culbs of hybridized Bulbus Fritillariae Ussuriensis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of hybridized Bulbus Fritillariae Ussuriensis.</p><p><b>METHOD</b>The chemical constituents were isolated by silica column chromatography and their structures were identified by physical and chemical eveidences and spectral analysis (IR, 1H-NMR, 13C-NMR, 2D-NMR, MS).</p><p><b>RESULT</b>Seven compounds were obtained and identified as (20S,25S)5alpha, 14alpha, 17beta-cevanine-6beta-hydroxy-3-one (hupehenirine, ZF1), (20S,25S)5alpha, 14alpha, 17beta-cevanine-3beta-hydroxy-6-one (hupehenizine, ZF2), (20R,25S)5alpha, 14alpha-cevanine-3beta,20beta-dihydroxy-6-one (peiminine, verticinone, ZF3), (20S,25S)5alpha, 14alpha, 17beta-cevanine-3beta, 6beta-dihydroxy (hupehenine, ZF4), (20R,25S)5alpha, 14alpha-cevanine-3beta, 6beta, 20beta-trihydroxy (isoverticine, ZF5), (20R,25S)5alpha, 14alpha-cevanine-3beta, 6alpha, 20beta-trihydroxy (peimine, verticine, ZF6), (20S,25S)5alpha, 14alpha, 17beta-evanine-6beta-hydroxy-3beta-O-beta-D-glucoside (hupeheninoside, ZF7).</p><p><b>CONCLUSION</b>Compounds ZF1-7 were isolated from hybridized Bulbus Fritillariae Ussuriensis for the first time.</p>
