Colitis is an inflammatory disease of the intestine with unknown etiology involving multiple immune, genetic, and environmental factors. We were interested to examine the effect of total extract from Dracocephalum kotschyi (D. kotschyi) Boiss. on the experimental colitis. D. kotschyi hydroalcoholic
Tilianin, a representative flavonoid ingredient of Dracocephalum moldavica L., has been used to treat several diseases for centuries, including atherosclerosis (AS). However, pharmacological mechanisms underlying its biological functions remain elusive. In the present study, we investigated
BACKGROUND
Dracocephalum kotschyi is traditionally used for its anti-inflammatory effects. We aimed to investigate the effects of ethyl acetate extract of D. kotschyi on the expression of key inflammatory mediators and main signaling molecules involved in the regulation of
Cerebral ischemia is a common disease and one of the most common causes of death and disability worldwide. The lack of glucose and oxygen in neuronal tissue leads to a series of inflammatory events, culminating in neuronal death. Eriodictyol is a flavonoid isolated from the Chinese herb
BACKGROUND
Dracocephalum moldavica Linn (Labiatae) is one of the ethnomedicinal drugs of Uygur in Xinjiang, China. This herb is mainly used in treating cardiovascular diseases, such as atherosclerosis. However, the mechanism of pharmacological activity of D. moldavica has been poorly
Separation of ethyl acetate fractionation of Dracocephalum peregrinum afforded three new flavonoid glucosides (1-3), and a new cyanogenic glucoside (4). Their structures were elucidated based on HR-electron spray ionization (ESI)-MS, EI-MS, UV, IR, 1D-, and 2D-NMR data. 1-4 were tested in vitro for
A chemical investigation of methanol extract from the roots of Dracocephalum taliense led to the isolation of a new aromatic abietane diterpenoid, 12-methoxy-18-hydroxy-sugiol (1), and one highly-oxygenated ursane triterpenoid, 2α,3α-dihydroxy-11α,12α-epoxy-urs-28,13β-olide (2), together with 15
BACKGROUND
Dracocephalum heterophyllum was a traditional Tibetan medicine possesses various pharmacological effects involved in anti-inflammatory, antibacterial activities. However, its anti-hepatitis, antioxidant activity and bioactive compounds have not been reported, the objective of this
Human pharyngeal squamous cell carcinoma is highly invasive and proliferative, and exhibits an extremely low 5-year survival rate due to poor understanding of the underlying pathogenic mechanisms, and lack of efficient treatment. It has been shown that the immunosuppressive microenvironment created
Immunomodulation using medicinal plants provides an alternative to conventional chemotherapy for several diseases, especially when suppression of inflammation is desired. The "Canon of Medicine", the epochal work of Avicenna, the great Persian scientist of the middle ages, provides comprehensive
Background:Dracocephalum peregrinum L., a traditional Kazakh medicine, has good expectorant, anti-cough, and to some degree, anti-asthmatic effects. Diosmetin (3',5,7-trihydroxy-4'-methoxyflavone), a natural flavonoid found in traditional Chinese herbs, is the main flavonoid in
Previously, total flavones of Dracocephalum (TFD), derived from Dracocephalum, were found to exert protective effects in cerebral ischemia reperfusion injury (CIRI) in middle cerebral artery occlusion (MCAO) rat model. However, the mechanisms underlying these observed effects of TFD on MCAO-induced
Previously, total flavones of Dracocephalum (TFD), derived from Dracocephalum, were found to exert protective effects in cerebral ischemia reperfusion injury (CIRI) in middle cerebral artery occlusion (MCAO) rat model. However, the mechanisms underlying these observed effects of TFD on MCAO-induced
BACKGROUND
A number of medicinal plants have been used to treat various immunological diseases. Nitric oxide (NO) has an important regulatory role in the various types of inflammatory processes.
OBJECTIVE
To investigate the NO modulatory activity of the extracts of several medicinal plants native to
