Karyotype analysis of obtained tetraploid in medicinal plant (Platycodon grandiflorus)
Platycodon grandiflorus is an important medicinal plant in China. Induction of polyploidy was successfully attempted in this medicinal plant using 0.05% colchicine semi-solid under 72 h by apical shoot tip treatment of young seedlings, and then 50% mutant plants were obtained. It was testified by the chromosome number in mitosis and its karyotype analysis for diploid control and obtained mutants. The results showed that...

Alkaloid constitution of Nerium oleander using gas chromatography-mass spectroscopy (GC-MS)
Oleander is an evergreen shrub or small tree from 5 to 25-ft tall containing gummy sticky sap in the dogbane family Apocynaceae. In this study, the alkaloid compounds of Nerium oleander (NO) have been evaluated. The chemical compositions of the leaf ethanol extract of N. oleander were investigated using gas chromatography-mass specroscopy (GC-MS). GC-MS analysis of N. oleander alkaloid leaf ethanol extract revealed the...
