Rauwolfia serpentina also known as Sarpagandha is an integral part of Ayurvedic medical system for over centuries for the treatment of various ailments. The leaves and roots of Rauwolfia serpentina contain alkaloids which are secondary metabolites. Major alkaloids identified are Reserpine, Rauwolfine, Serpentine, Sarpagine, Ajmaline, Yohimbine and Ajmalicine. Insulin binds to insulin receptors ...
Ergot alkaloids, produced by the plant parasitic fungi Claviceps purpurea are important pharmaceuticals. The chemistry, biosynthesis, bioconversions, physiological controls, and biochemistry have been extensively reviewed by earlier authors. We present here the research done on the organic synthesis of the ergot alkaloids during the past two decades. Our aim is to apply this knowledge to the sy...
Amaryllidaceae is a well-known family for its high alkaloidal content. These alkaloids comprise a unique group of bases that have been found to occur in this family. The Amaryllidaceae alkaloids represent a large and still expanding group of isoquinoline alkaloids, the majority of which are not known to occur in any other family of plants. This article reports on the phytochemical investigation...
Alkaloids induce programmed cell death in bloodstream forms of trypanosomes (Trypanosoma b. brucei).
The potential induction of a programmed cell death (PCD) in Trypanosoma b. brucei by 55 alkaloids of the quinoline, quinolizidine, isoquinoline, indole, terpene, tropane, steroid, and piperidine type was studied by measuring DNA fragmentation and changes in mitochondrial membrane potential. For comparison, the induction of apoptosis by the same alkaloids in human leukemia cells (Jurkat APO-S) w...
background: plants infection with microorganisms as well as physical factors such as osmotic stresses especially drought stress induced particular secondary metabolite production. objective: plant root and shoot hyoscyamine (hyo) and scopolamine (sco) variations were investigated under three water deficit stress (wds) levels as 30 (w1), 60 (w2) and 90 % (w3) water depletion of field capacity an...

background and objectives: hyoscyamus reticulatus contains two distinguished tropane alkaloids, hyoscyamineand scopolamine and both of the compounds possesspotential acute or chronic toxicity. in the present study, a simple and efficient transformation system was established for in vitro hairy roots induction in hyoscyamus reticulatus. methods: effect of different factors including agrobacteriu...
Pilocarpus microphyllus (Rutaceae), popularly known as jaborandi, is the only commercial source of an imidazole alkaloid named pilocarpine. In the present study, the variation in the profile of imidazole alkaloids in different seasons and in different parts of the P. microphyllus plant during the summer was analyzed by electrospray ionization mass spectrometry in the positive ion mode [ESI(+)-M...
BACKGROUND The Macleaya spp., including Macleaya cordata and Macleaya microcarpa, are traditional anti-virus, inflammation eliminating, and insecticide herb medicines for their isoquinoline alkaloids. They are also known as the basis of the popular natural animal food addictive in Europe. However, few studies especially at genomics level were conducted on them. Hence, we performed the Macleaya ...
