background & aim: papaver bracteatum lindl.  (papaverace) is an important pharmaceutical plant which contains isoqinoline alkaloids. isoqinoline alkaloids constitute one distinct group of secondary metabolites of the papaverace family. codeine and thebaine are important alkaloids of papaver bracteatum which use widely due to its medicinal properties. therefore it is necessary to determinati...

A requirement for understanding morphogenesis is being able to quantify expansion at the cellular scale. Here, we present new software (RootflowRT) for measuring the expansion profile of a growing root at high spatial and temporal resolution. The software implements an image processing algorithm using a novel combination of optical flow methods for deformable motion. The algorithm operates on a...

Papaver bracteatum Lindly (Papaveraceae) is an endemic species of Iran which has economic importance in drug industries. The main alkaloid of the plant is thebaine which is used as a precursor of the semi-synthetic and synthetic compounds including codeine and naloxone, respectively. This systematic review focuses on main component of Papaver bracteatum and methods used to determine thebaine. ...

Glucosyloxybenzyl 2-isobutylmalates are one group of important active constituents in the tubers of Gymnadenia conopsea R. Br. and Coeloglossum viride (L.) Hartm. var. bracteatum (Willd.). For the purpose of quality evaluation of these two Chinese herbal medicines, it is necessary to use a rapid and reliable assay that is suitable for the determination of their active constituents. A high-perfo...

The genus Alyssum L. belongs to the subtribe Alyssinae, tribe Alysseae and family Cruciferae (Brassicaceae). This genus is one of the largest genera of the family of Cruciferae in Iran, and seems to be the most problematic genus in which the boundary of certain species is not completely clear due to the polymorphism of morphological characters. The main objective of this research is to stud...

Recently there has been an increase in the demand of polysaccharides. Polysaccharides from plants have the advantage over those from animals because of their friendly image towards consumers. A lot of work has been done to study the chemical composition and functionality of polysaccharides. However, there is still place in the polysaccharide market for new sources of plant polysaccharides. Acan...
