Six Sceletium (Mesembrine) alkaloids (l)-(6) are identified together with NN-dimethyltyramine (10) as constituents of Sceletium subvelutinum. The alkaloids (l)-(6) incorporate label from [7-14C]tyramine [as (8)]and 3-([35-3H2]-4-hydroxyphenyl)propionic acid (13) as expected; notably 3-([35-3H2]-4-hydroxyphenyl)propanal (15) is a more efficient alkaloid precursor than is the acid (13) and the aldehyde
鉴定出六个Sceletium(Mesembrine)生物碱(1)-(6)与N N-二甲基酪胺(10)一起作为Sceletium subvelutinum的成分。生物碱(1) - (6)从一体化标签[7- 14 C]酪胺[如(8)]和3 - ([35- 3 ħ 2 ] -4-羟基苯基)如预期丙酸(13); 尤其是3 - ([35- 3 ħ 2 ] -4-羟基苯基)丙醛(15)是一种更有效的前体生物碱比是羧酸(13)和醛被推断为在生物合成中的关键中间体Sceletium生物碱。N-甲胺(21)是Setletium生物合成中的重要晚期中间体生物碱或与该中间体密切相关。与(22)=(21)相比,胺(20)的掺入效率较低。
