Eighty-seven methanol extracts of medicinal plants, most of them are currently used in Vietnamese oriental medicine, were screened for NF-κB inhibitory activity. Seven methanol extracts showed strong to moderate inhibitory activity. These include the extracts of Crinum latifolium (leaves), Evodia rutaecarpa (fruits), Polygonum cuspidatum (rhizoma), Perilla ocymoides (leaves), Rubia cordifolia (...

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...
