Purpose: To isolate essential oil from the aerial parts of Scutellaria baicalensis using GS-MS, and to assess its insect-killing effect against booklice (Liposcelis bostrychophila).Methods: The S. was hydro-distilled subjected gas chromatographic mass spectroscopic (GC-MS) techniques. components with insectkilling potentials were fractionated through bioactivity-guided isolation, isolated scree...

Cytostatic therapy of patients with lung cancer is attended with decrease in the relative number of T-lymphocytes and their theophylline-resistant population. Patients who were given SB showed a tendency towards increase of these parameters during antitumor chemotherapy. The immunoregulation index (IRI) in this case was approximately twice the background values during the whole period of invest...

Scutellaria baicalensis has a wide range of biological activities and has been considered as an important traditional drug in Asia and North America for centuries. A partial-length cDNA clone encoding phytoene synthase (SbPSY) and full-length cDNA clonesencoding phytoene desaturase (SbPDS), ξ-carotene desaturase (SbZDS), β-ring carotene hydroxylase (SbCHXB), and zeaxanthin epoxidase (SbZEP)were...

Scutellaria is one of the largest genera in Lamiaceae with an estimated 400–500 species a nearly worldwide distribution. Most occur N hemisphere, Caucasus and wider Irano-Turanian region housing large number taxa, many them considered endemic. We present overall phylogeny monophyletic genus based on rapidly evolving plastid regions (matK-trnK, rpl16, trnL-F). Three well-supported clades are evi...

objective: scutellaria luteo-caerulea bornm. & snit. is one of the species of genus scutellaria, within the family of the lamiaceae, that is used for immune system stimulation and antibacterial effects in traditional medicine in iran. the aims of this study were to analyze essential oils and mineral element contents of leaves of  s. luteo-caerulea in flowering stage of development. materials an...
