Macrophage apoptosis is salient in advanced atherosclerotic lesions and is induced by several stimuli including endoplasmic reticulum (ER) stress. This study examined that α-asarone present in purple perilla abrogated macrophage injury caused by oxysterols via ER stress- and autophagy-mediated mechanisms. Nontoxic α-asarone at 1-20 μM attenuated 7β-hydroxycholesterol-induced activation of eukar...
Response surface methodology (RSM), based on a central composite design, was used to determine the best liquid-to-raw material ratio (10:3-15 mL/g), extraction time (1-3 h), and ethanol concentration (50%-100%) for maximum content of α-asarone from Perilla frutescens (PF) extract. Experimental values of α-asarone were 9.51-46.36 mg/g; the results fitted a second-order quadratic polynomial model...
Acori Tatarinowii Rhizome (ATR; the dried rhizome of Acori tatarinowii Schott) is a well-known herb being used for mental disorder in China and Asia. Volatile oil is considered as the active ingredient of ATR, and asarones account for more than 90% of total volatile oil. Here, the protective effects of ATR oil and asarones, both α-asarone and β-asarone, were probed in cultured rat astrocytes. T...
Emerging evidence suggests that activated astrocytes play important roles in AD, and β-asarone, a major component of Acorus tatarinowii Schott, was shown to be a potential therapeutic candidate for AD. While our previous study found that β-asarone could improve the cognitive function of rats hippocampally injected with Aβ, the effects of β-asarone on astrocytes remain unclear, and this study ai...
A sensitive and specific gas chromatographic-mass spectrometry with selected ion monitoring (GC-MS/SIM) method has been developed for simultaneous identification and quantification of α -asarone, β-asarone, and methyl eugenol of Acorus tatarinowii Schott in rat plasma. Chromatographic separation was performed on a Restek Rxi-5MS capillary column (30 m × 0.32 mm × 0.25 μm), using 1-naphthol as i...
The aim of this research was to determine the chemical composition of the essential oil of Acorus calamus rhizomes, its insecticidal activity against the booklouse, (Liposcelis bostrychophila) and to isolate any insecticidal constituents from the essential oil. The essential oil of A. calamus rhizomes was obtained by hydrodistillation and analyzed by GC-FID and GC-MS. A total of 32 components o...
ABSTRACT The Asian traditional medicinal plant Acorus calamus and its component α-asarone exhibited various biological activities, such as antiinflammation antioxidant effects. In the present study, we investigated in vitro effects of A. extract on oxidative stress- endoplasmic reticulum (ER) stress–induced cell death hippocampal HT22 cells. both significantly suppressed induced by stress induc...
This study focused on five different subspecies of Portuguese Daucus carota L., to identify the main compounds in essential oils umbels from each subspecies. The isolation was performed by hydrodistillation methods followed further composition analysis gas chromatography-mass spectrometry, ultimately demonstrating that had major compounds. concluded found subsp. maritimus were geranyl acetate, ...
چکیده : دو گیاه perovskia abrotanoides karel و zeravschania aucheri در سایه تحت جریان ملایم هوا خشک شدند. اسانس گیری از گیاهان خشک شده توسط دو روش تقطیر با آب و میکرواستخراج فاز جامد در فضای فوقانی انجام گرفت و اسانس ها با استفاده ار روش کروماتوگرافی گازی- طیف سنج جرمی (gc-ms) مورد تجزیه و تحلیل قرار گرفتند. ترکیبات عمده شناسایی شده در اسانس برگ و گل و ساقه گیاه p.abrotanoides عبارتند از: ...
