BACKGROUND: Chamomile (Matricaria recutita L.) has a long history of use in herbal medicine with various applications, and the flower heads contain numerous secondary metabolites which are medicinally active. In the major crop plants, next generation sequencing (NGS) approaches are intensely applied to exploit genetic resources, to develop genomic resources and to enhance breeding. Here, genotyping-by-sequencing (GBS) has been used in the non-model medicinal plant chamomile to evaluate the genetic structure of the cultivated varieties/populations, and to perform genome wide association study (GWAS) focusing on genes with large effect on flowering time and the medicinally important alpha-bisabolol content...

A simple and efficient multi residue method was developed, for the analysis of 160 pesticides by GC-MS/MS in herbal plants. The developed method employs pesticide residue extraction by EtAC/ n. hexane (6:4) with a cleanup step using florisil/ PSA mixture. The optimized conditions have resulted in lower co-extracted matrix components than those extracted using EtAC or MeCN (QuEChERS method), according to FTIR and full scan GC/MS analyses. In addition, the developed method (EtAC/ Hexane) eliminates the evaporation step that is usually performed when using MeCN as an extraction solvent prior to the GC-MS/MS injection...

Bisabolol (α-(-)-bisabolol) is a sesquiterpene which is a part of the essential oil of a variety of plants, but its common source is German chamomile. Several bioactivities including anti-inflammatory, anti-nociceptive, and anti-tumor effects were attributed to bisabolol. However, the neuropharmacological properties of bisabolol have not yet been reported. The present study evaluated behavioral effects of bisabolol using elevated plus maze (EPM), open field test (OFT), and rotarod test. Moreover, this study also examined whether the 5-HT1A and GABAA-benzodiazepine receptor systems are involved in the anxiolytic-like effects of bisabolol...
