The aim of this study was to investigate the Stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. The volatile constituents from the aerial parts of Stachys turcomanica growing wild in Iran were obtained by hydrodistillation and analyzed by GC and GC-MS. In the GC-MS analysis, Forty-six components representing 81.1% of the oil were identifie...

The objective of this study is determination the volatile compounds of Matricaria chamomilla of an inorganic–organic hybrid material based on ZnO nanoparticles anchored to a composite made from polythiophene and hexagonally ordered silica (ZnO/PT/SBA-15) as a solid-phase fiber microextraction (SPME). Microextraction techniques with nanoparticles ZnO/PT/SBA-15 resulted in a more efficient analyt...

Abbreviations: Diabetic neuropathic pain (DNP), diabetic neuropathy (DN), diabetic mice (DM), oxidative stress (OS), inflammatory cytokines (IC), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), proinflammatory cytokines (pro-IC), neuropathic pain (NP), nuclear factor-κB (NF-κB), Reactive oxygen species (ROS), nitric oxide (NO), N-methyl-Daspartate (NMDA), mitogen-activated protein kina...

pycnocycla spinosa aerial parts were collected weekly during four-month growth. hydrodistillation and gas chromatography coupled with mass spectroscopy techniques were used for essential oil and sesquiterpenes investigation. thirty-four components were identified, of which the characteristic sesquiterpenes were a -copaene, caryophyllene, a -humulene, b-ionene, d-cadinene, a -calacorene, caryoph...

in this study, the relationship among four species of polygonum (including p. hyrcanicum (three samples), p. persicaria, p. avicular, and p. hydropiper) was investigated by gc profiling. furthermore, the major compounds of the ethylic ether extract of p. hyrcanicum were identified by gc/ms as: α-bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydrate (13.0%), α-elemol (10.5%) and trans-longip...

A series of supramolecular aggregates were prepared using a poly(propylene oxide)-poly(ethylene oxide)-poly(propylene oxide) (PPO-PEO-PPO) block copolymer and β- or α-cyclodextrins (CD). The combination of β-CD and the copolymer yields inclusion complexes (IC) with polypseudorotaxane structures. These are formed by complexation of the PPO blocks with β-CD molecules producing a powder precipitat...

The aim of the present study was to research the role of nitric oxide (NO) as a mediator of alpha (α)-asarone effect at the pentylenetetrazol (PTZ)-induced epileptiform discharge in rat. α-Asarone that was injected intraperitoneally twenty minutes before PTZ injection suppressed the clonic discharge effectively and the significant actions lasted for 30 min with no change of clonic amplitude. Ad...

Cryptolepine, an indoloquinoline alkaloid in Cryptolepis sanguinolenta, has anti-inflammatory property. In this study, we aimed to evaluate the effects of cryptolepine on lipopolysaccharide (LPS)- induced neuroinflammation in rat microglia and its potential mechanisms. Microglial activation was induced by stimulation with LPS, and the effects of cryptolepine pretreatment on microglial activatio...

A reatividade de duplas ligações terminal e trissubstituída de monoterpenos com HSCN foi examinada por CG evidenciando que fatores cinéticos são responsáveis pela adição quimiosseletiva em duplas ligações terminais em terpenos. O resultado mostra que a adição é cerca de 17 vezes mais rápida em duplas terminais do que em duplas trissubstituídas e que a presença do primeiro grupo SCN impede a ent...
