Islet cell tumors of the pancreas found in rats given pyrrolizidine alkaloids from Amsinckia intermedia Fisch and Mey and from Heliotropium supinum L.

Pyrrolizidine Alkaloid– Containing Toxic Plants (<i>Senecio, Crotalaria, Cynoglossum, Amsinckia, Heliotropium, </i> and <i>Echium</i> spp.)

Pyrrolizidine alkaloids from Heliotropium transoxanum Bunge

Background and objectives: The plants belonging to the genus Heliotropium L. (Boraginaceae) are the main sources of toxic pyrrolizidine alkaloids (PAs). In the present study, we have investigated the PAs of the aerial parts of Heliotropium transoxanum Bunge, a perennial species native to Iran. Methods: Silica gel column chromatography and silica gel PTLC were applied ...

"Blinding" of shoots and a leaf gall in Amsinckia intermedia induced by Anguina amsinckia (Steiner and Scott, 1934) (Nemata, Tylenchidae), with a note on the absence of a rachis in A. amsinckia.

"Blinding" and a leaf gall induced on Amsinckia intermedia Fisch. and Mey. by Anguina amsinckia (Steiner and Scott) are described. A. amsinckia induced blinding by galling the terminal apical meristem of its host. The leaf gall was formed by a ventral curling of the distal edge of the leaf. The absence of a rachis in the ovary of A. amsinckia is noted.

Evaluation of Hepatotoxicity of Common Doses of Decoction of Echium Amoenum Fisch and C.A. Mey in Rats

Introduction: Dried violet–blue petals of Echium amoenum Fisch. and C.A. Mey. (Boraginaceae) have long been used as a tonic, tranquillizer, diaphoretic and as a remedy for coughing, sore throat and common cold. These dried violet–blue petals are known in traditional medicine of Iran as Gol-e- Gavzaban. Because the decoction of its dry petals has hepatotoxic pyrrolizidine alkaloids, in the prese...
