Two new diterpenes, named sibiriquinone A (1) and B (2), along with four known diterpenes have been isolated from the aerial part of Veronicastrum sibiricum. Their structures were elucidated by spectroscopy. The isolated compounds showed significant immunosuppressive activities.
The rapid spread of invasive plants makes their management increasingly difficult. Remote sensing offers a means of fast and efficient monitoring, but still the optimal methodologies remain to be defined. The seasonal dynamics and spectral characteristics of the target invasive species are important factors, since, at certain time of the vegetation season (e.g., at flowering or senescing), plan...

background: iran is a land of great heritage of ancient medical scholars. herbal medicines, as a basement of treatment of diseases have been clearly described in the medical texts of these scholars including rhazes, avicenna, and others. numerous plants are introduced in these texts to treat those diseases likely to be infective ones. few attempts have been made to evaluate ethnopharmacological...
Immunogenetic mechanisms operating within the immune system are known to influence cytokine profiles and disease susceptibility. Yet the role of the individual's neurohormonal background in these processes remains undefined. Hormonal imbalances are documented in immune-related diseases, but it is unclear whether this represents a secondary phenomenon or a primary "defect" related to specific ne...
The fluorescent in situ hybridization (FISH) technique has been applied to somatic chromosomes in the medicinally important species, Bunium persicum, to elucidate its karyotypes. The bicolour FISH technique involving 18S-5.8S-26S and 5S ribosomal RNA genes as probes was used to assign physical localization and measurement of rDNA sites on homologous pairs of chromosomes. The two 18S-5.8S-26S rR...
This work is focused on nine Heracleum taxa (Apiaceae): H. sphondylium, sibiricum, montanum, ternatum, pyrenaicum subsp. pollinianum, orsinii and verticillatum, belonging to the sphondylium group, orphanidis, all from sect. Heracleum, as well austriacum siifolium Wendia. The aim was isolate headspace (HS) fractions 17 fruit samples (collected taxa) 13 root eight Heracleum), investigate their co...
