the volatile constituents of the aerial parts of varthemia. persica dc. var. persica, growing wild in iran, were investigated by gc-ms. sixty seven constituents were identified. ?-cadinene (9.7%), selin-11-en-4-?-ol (5.30%), germacrene d (4.9%), bicyclogermacrene (4.7%), ??muurolene (4.7%), ?-eudesmol (4.52%), ?-himachalen oxide (3.6%), ?-eudesmol (3.54%), ?-bourbonene (3.21%) were found to be ...

Three types of phenolic acids (caffeic, ferulic, and chlorogenic acid) were identified quantified in two halophytic plants (Salicornia bigelovii Salicornia sinus-persica). Analysis was performed using a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) system via the standard addition method. The matrix effect (ME), recovery efficiency (RE), process (PE) parameters ev...

sights into host–microbe interactions. Our report confirms a novel Borrelia IGS sequence type detected in situ from 2 relapsing fever patients. This species showed greatest homology with the relapsing fever borreliae from Africa, B. recurrentis and B. duttonii, but not with B. microti, which is transmitted by O. erraticus ticks, previously believed to be the only soft tick species in this regio...

Veronica persica Poiret (Family: Scrophulariaceae), the `Common Field Speedwella or `Persian speedwella, is a neophytic weed originally from south-west Asia and widely distributed in the temperate regions (USDA-ARS GRIN database, 1999; Fischer, 1987; Holm et al., 1979). The plants were garden weeds and collected in #ower near Aberystwyth (Tyn-y-Graig, Wales), and a voucher specimen (N9623) of t...

The influences of controlled atmosphere (CA) and storage time on ultrastructural degradation of chelate-soluble pectin (CSP) in yellow peaches (Prunus persica L. Batsch.) were investigated. Freshly harvested peaches were stored at 2 ◦C under CA (CA1, 2% O2 + 10% CO2; CA2, 5% O + 5% CO ) or regular atmosphere conditions. Qualitative and quantitative aspects of CSP polymers were studied by atomic...
