✦ Synopsis

Prompted by reports of the anti-tumor activity of Palicourea species1 and the isolation of alkaloids of unknown structures*, Palicourea alpina* (SW.) DC (Rubiaceae) was extracted for alkaloids. Counter-current separation yielded in addition to harman, a new alkaloid, which we have named palinine, m.p. 166.5 -168Oc, Iarj;8 -252.3O (f%OIi) and which analysed for C27H32N2010. We now report evidence supporting the 6-carboline glycosidic structure (2). s R=H lb: R=Ac *Voucher No.31.130
