Sophorine was isolated from Sophora alopecuroides (26). The nature of MS decay showed that sophorine is a quinolizidine alkaloid of the lupinine type. The IR spectrum suggests the presence of a franj-quinolizidine moiety (2675-2945 cm ) and an — NH—CO— group (1605 and 1683 cm ). On the basis of chemical shift analysis and signal multiplicity of H- and C-NMR spectra as well as biosynthetic considerations, structure 59 was proposed for sophorine. [Pg.144]

Sophoridine was isolated from Sophora alopecuroides L. (190,191), Lep-torhabdos parviflora Benth. (192), S. flavenscens Ait. (22), and Euchresta jap-onica Benth. (40). (-l-)-Sophoridine was also isolated from Leontice albertii Rgl. (196,197). The structure of the carbon-nitrogen skeleton was established with the formation of octodehydromatrine (177) on dehydrogenation over palladized... [Pg.169]

Neosophoramine was isolated from Sophora alopecuroides L. (191,207,222,223). There are no rons-quinolizidine bands in the IR spectrum, but there is a lactam carbonyl absorption band at 1650 cm. The MS spectrum is characterized by peaks of the molecular ions M (244) and M - 1 (243) and by ion peaks at miz 215, 149, 136, and others, typical for matrine alkaloids containing an a-pyiidine ring. A comparative study of UV, IR, H-NMR, and mass spectroscopic data of neosophoramine (194), sophoramine (195), and iso-sophoramine (196) showed that these alkaloids differ mainly in the configuration... [Pg.176]

Another six novel flavonostilbenes, alopecurones A-F (782-787), were isolated from the roots of Sophora alopecuroides. Their structures are composed of a flavanone condensed with a resveratrol (1). Absolute configurations of alopecurones A-F (782-787) were determined by means of CD compared with model compounds [342]. [Pg.552]
