β-Asarone (2, 4, 5-trimethoxy-(Z)-1-propenylbenzene) was obtained from Acorus calamus. Nitration of β-asarone with AgNO2/I2 in ether yielded 1-(2, 4, 5-trimethoxy phenyl)-2-nitropropene (1) but with NaNO2/I2 in ethylene glycol obtained 1-(2, 4, 5-trimethoxy phenyl)-1-nitropropene (2). Compound 2 was prepared for the first time and characterized using IR, (1)H-NMR, (13)C-NMR, and GC-MS spectra a...
Rhizosphere oxygen profiles are the key to understanding the role of wetland plants in ecological remediation. Though in situ determination of the rhizosphere oxygen profiles has been performed occasionally at certain growing stages within days, comprehensive study on individual roots during weeks is still missing. Seedlings of Acorus calamus, a wetland monocot, were cultivated in silty sedimen...
BACKGROUND Asaronaldehyde (2, 4, 5-trimethoxybeznaldehyde) is an active component of Acorus gramineus rhizome. This study aims to evaluate the anti-Candida efficacy of asaronaldehyde and its three structural isomers, namely, 2, 3, 4-trimethoxybenzaldehyde, 3, 4, 5-trimethoxybenzaldehyde, and 2, 4, 6- trimethoxybenzaldehyde. METHODS Susceptibility testing of test compounds was carried out usin...
Anticonvulsant property of Acorus calamus is known. Since combination therapy can lower the dose of individual drug and dose related toxicities, in this study, the effect of co-administration of hydroalcoholic extract of A. calamus (HAEAC) on conventional antiepileptic drugs (AEDs), sodium valproate and carbamazepine was determined using pentylenetetrazole-induced seizures model in rats. On com...

This investigation was aimed to provide a pharmacologic basis to the medicinal use of Acorus calamus in cardiovascular disorders. In normotensive anesthetized rats, crude extract of Acorus calamus and its ethylacetate and nHexane fractions caused a fall in mean arterial pressure. In rabbit aorta rings, crude extract was more potent against high K (80 mM), ethylacetate against phenylephrine (1 m...
AIM: Prolonged exposure to stress mainly affects the cognitive functions of the brain by inducing neuronal damage mediated through oxidative stress. Acorus calamus (AC) has long been used in Indian folk medicine for various central nervous system (CNS) abnormalities. Hence the present study investigates the effect AC on learning and memory in rats. MATErIAL and METHods: Adult Wistar male rats w...
