From the root bark of the apocynacea Hedranthera barteri (Hook. f.) Pichon were isolated the known indole alkaloids vobtusine (1), voacamine (2), callichiline (3), voacangine (4) and conoflorine (5), as well as the unknown plant bases amataine, goziline and owerreine, and also beninine and 1, 2-dehydrobeninine. The structures of the two last mentioned alkaloids were shown in an earlier publication

吲哚生物碱vobtusine(1),voacamine(2),callichiline(3),voacangine(4)和conoflorine(5)。未知的植物基础是
金刚烷,戈兹林和麦角茶碱,还有贝宁和1,2-脱氢贝宁。在较早的出版物中,最后提到的两种
生物碱的结构分别为6和7, 分别。Amataine,goziline和owerreine是双-
吲哚生物碱,其中它们的
化学和光谱的基础上(特别是质谱)属性被分配得到结构8,9和10分别。
