Genus Equisetum L: Taxonomy, toxicology, phytochemistry and pharmacology.

Introduction: The genus Equisetum (Equisetaceae) is cosmopolitan in distribution, with 41 recognized species. Several species of Equisetum are widely used in treating genitourinary and related diseases, inflammatory and rheumatic problems, hypertension, and wound healing in traditional medicine practices worldwide. This review intends to present information on the traditional uses, phytochemical components, pharmacological activities, and toxicity of Equisetum spp.

Therapeutic potential of phytoconstituents of edible fruits in combating emerging viral infections.

Plant-derived bioactive molecules display potential antiviral activity against various viral targets including mode of viral entry and its replication in host cells. Considering the challenges and search for antiviral agents, this review provides substantiated data on chemical constituents of edible fruits with promising antiviral activity. The bioactive constituents like naringenin, mangiferin, α-mangostin, geraniin, punicalagin, and lectins of edible fruits exhibit antiviral effect by inhibiting viral replication against IFV, DENV, polio, CHIKV, Zika, HIV, HSV, HBV, HCV, and SARS-CoV.

Vasorelaxant property of Plectranthus vettiveroides root essential oil and its possible mechanism.

Ethnopharmacological Relevance: Plectranthus vettiveroides (Jacob) N.P. Singh & B.

Root essential oil of relaxes rat isolated thoracic aorta - an approach.

Root of (L.) Roberty has been used in Siddha system of medicine to treat hypertension. The present study was therefore to investigate the vasorelaxation effect of root essential oil of using rat isolated thoracic aortic rings.

Chemical characterization, antioxidant, antibacterial and enzyme inhibitory properties of Canthium coromandelicum, a valuable source for bioactive compounds.

The present study aimed at chemical characterization of Canthium coromandelicum leaf extracts (CCLE) and their in vitro pharmacological (antioxidant, enzyme inhibitory, and antibacterial) activities. Chemical characterization includes chemical profile of six extracts of CC by Gas chromatography - Mass spectrometry (GC-MS) analysis and total phenolics and flavonoids by spectrophotometric methods. Antioxidant activity was determined using eight assays.

Evaluation of chemical composition, antioxidant and anti-hyperglycemic activities of the essential oil based nanoemulsions of .

In the present study, antioxidant and anti-hyperglycemic activities of nanoemulsions of the leaf essential oils of Thwaites collected from two different locations in the Western Ghats namely, Kannikatty, Kalakad Mundandurai Tiger Reserve, Tamil Nadu (Cl) and Karamanayar, Agasthyamalai hills, Kerala (Cl), India were studied. Essential oils were extracted from the leaves and characterized by GC-FID and GC-MS. Slight variation in the composition of leaf essential oils was observed.

Cumin scented leaf essential oil of Cinnamomum chemungianum: compositions and their in vitro antioxidant, α-amylase, α-glucosidase and lipase inhibitory activities.

As part of our work on prospecting of Cinnamomum of the Western Ghats, chemical compositions, antioxidant, α-amylase, α-glucosidase and lipase inhibitory activities of leaf essential oil (EO) of Cinnamomum chemungianum were evaluated. Chemical characterisation of the cumin scented leaf EO from five locations in the southern Western Ghats revealed that they were highly varied. EO from Kannikatti (CC) exhibited good α-amylase inhibitory activity with IC value of 5.

Variation in volatile constituents of Cinnamomum keralaense, endemic to the Western Ghats, India.

Leaf essential oils (EOs) of Cinnamomum keralaense, an endemic species to Southern Western Ghats, India, were investigated. Leaves were collected from three distinct populations and hydro-distilled to obtain EOs, which were analysed by GC-FID and GC-MS. A total of 68 constituents was identified from three EOs.

Characterization of the leaf essential oils of an endemic species Cinnamomum perrottetii from Western Ghats, India.

Essential oils from the leaf of Cinnamomum perrottetii Meissn. collected from three distinct populations in the southern Western Ghats, India were analysed by GC-FID and GC-MS. A total of 56 volatile constituents representing 92.
