Glyphomerus aylax sp. n. (Hymenoptera: Torymidae) from Bulgaria

Glyphomerus aylax sp. n. (Hymenoptera: Torymidae) from Bulgaria The new species Glyphomerus aylax is described and illustrated on the basis of specimens that emerged from galls of Aylax hypecoi Trotter (Cynipidae) on Hypecoum imberbe (Hypecoaceae). A key to all species of Glyphomerus is presented. Biological notes of the new species are given.

Five alkaloids from Hypecoum leptocarpum

Five new alkaloids, leptocarpinine, leptopine, leptopinine, leptopidine and leptopidinine were isolated, together with protopine, isohyperectine and oxohydrastinine, from Hypecoum leptocarpum . The structures were elucidated by spectral evidence.

(±)-8-oxohypecorinine from Hypecoum procumbens var. glaucescens

A new secoberbine alkaloid, (±)-8-oxohypecorinine, together with (±)-hypecorinine, isocorydine, allocryptopine, cryptopine and protopine were isolated from Hypecoum procumbens var. glaucescens and spectroscopically characterized.

Feruloyltyramine from Hypecoum

Feruloyltyramine amide has been isolated from Hypecoum parviflorum and from H. imberbe.

Alkaloids of Hypecoum erectum structure of hypecorine and hypecorinine

Two new alkaloids (hypecorine and hypecorinine) have been isolated fromHypecoum erectum L., and their structures have been determined.
