Linaria, transiliensis

Vasicinone (37) is an oxidation product of vasicine. Mehta et al. 136) have found that the crude total alkaloids from Adhatoda vasica contain predominantly vasicine, but that gradual conversion of vasicine to vasicinone takes place during countercurrent distribution and partition chromatography, probably as a result of autooxidation. Pure vasicine similarly undergoes autooxidation to vasicinone. (37) has also been isolated from the seeds 121, 122, 136) and other parts 163, cf. 775) of Peganum harmala as well as Linaria transiliensis 164). The physical properties are as follows uv, max 227, 272, 302 and 315 nm ir, the short wavenumber part of the spectrum contains absorptions at 3115, 2924, 1658, 1454, 1385, 1331, 1291, 1209, 1179, 1104, 1080, 1028, 987, 970, 896, 883, 867, 854, 774, 749, 720, 694 cm H-nmr (CF3COOH), 5 7.3—7.8, aromatic protons 8.05, C8-H 5.56, C3-H 2.64-h2.21, C2-H2 3.92-h4.32, CI-H2.
