The present study was to analyze the occurrence of mycorrhizal diversity in 20 medicinal plants of Vriddhachalam, Cuddalore District, Tamil Nadu and to explore for structures correlated to the possible functional position of the symbiosis. Arbuscular mycorrhizal fungal colonization ranged from 24-81%. The highest infection was found in Justicia gendarussa and lowest in Naregamia alata. AM fungal spore population with a range of 140 to 620 in100 g of rhizosphere soils was detected. The maximum spore population was observed in the species, Maranta arundinaceae (620/100g of soil) and the minimum in Achyranthes aspera (140/100g of soil). The AMfungal species were isolated which belongs to four genera (Aculospora, Gigaspora, Glomus and Scutellospora) and among them, Glomus was dominant genera. The soil pH was also...

Pterospermum acerifolium is a common to plant in India is considered carminative, stimulant and emmenagogue. In the present study, the ethanol extract of the bark of Pterospermum acerifolium has been evaluated for Neurochemical study. Treatment with ethanolic extract of Pterospermum acerifolium was found to significantly decrease the serum levels of adrenocorticotropic hormone (ACTH), corticosterone (CORT) and -endorphin (-EP) as well as the brain and serum level of norepinephrine (NE). Furthermore, ethanolic extract of Pterospermum acerifolium was able to significantly reverse the chronic stress by decreasing the brain and serum levels of the monoamine neurotransmitters dopamine (DA), 5-hydroxytryptamine (5-HT). The results obtained from this study suggested that the memory-enhancing effect of ethanolic extract of Pterospermum acerifolium was mediated through regulations of neurochemical and neuroendocrine systems. From the present study, it was concluded that herbal drugs could be potentially used to control the state of CNS disorders. Further investigations are, however, necessary to explore mechanism(s) of action involved in these pharmacological activities....

The antioxidant properties of 20 herbs and 28 herbal teas were analyzed in comparison with those of Camellia sinensis based on total phenolic content (TPC), free radical scavenging (FRS) activity, ferric reducing power (FRP) and ferrous ion chelating (FIC) ability. The main objective was to find out if there are herbs and herbal teas with antioxidant properties comparable to or superior to those of C. sinensis. Results showed that TPC, FRS, and FRP of C. sinensis leave outperformed all herbs. FIC values were, however, weaker than those of banaba and cashew leaves. TPC, FRS, and FRP of C. sinensis teas outperformed all herbal teas except those of banaba, lemon myrtle and stevia. Eleven herbal teas displayed stronger FIC values than C. sinensis teas with those of banaba, spearmint, and peppermint being the most potent. Overall, C. sinensis leaves and teas remain the king of antioxidants based on phenolic content and primary antioxidant properties of FRS and FRP, but not on secondary antioxidant properties of...

Many herbal remedies have been employed in various medical systems for the treatment and management of different diseases. The plant Lagenaria siceraria, a plant belonging to the family Cucurbitaceae, has been used in the different system of traditional medication for the treatment of diseases and ailments of human beings. The n-hexane extract of Lagenaria siceraria was screened for antimicrobial activity against a wide range of both gram-positive and gram-negative bacteria by the disc diffusion method. The results obtained were compared with that of a standard antibiotic, kanamycin. The n-hexane extract showed significant antimicrobial activity against Escherichia coli (17.25 mm), and Salmonella typhi (17.80 mm). But there was no antimicrobial activity against Vibrio cholera, Bacillus cereus, Bacillus subtilis, and Staphylococcus...

2-Amino-1-aryl-1, 4, 5, 6, 7, 8-hexahydro-4-phenyl-quinoline-3-carbonitrile derivatives were synthesized by the reaction of cyclohexanone (1) with 2-benzylidine-malononitrile (2) and the appropriate of aniline derivatives. The reactivity of some of these newly synthesized derivatives toward carbon disulfide and further toward hydrazonoyl halides were also studied. Also, the antimicrobial activity of the newly synthesized derivatives was...
