Sensitive skin is a common condition that concerns many people in the world. This syndrome is defined by the occurrence of unpleasant sensations such as stinging and burning in response to stimuli that normally should not provoke such sensations. The main hypothesis attributed to the occurrence of sensitive skin is the disruption of the epidermal barrier and a greater penetration of substances such as irritants. In keratinocytes, the NF-κB pathway, which plays an important role in orchestrating inflammatory responses, is then activated. Regulation of this activation is a key issue to control inflammation. Due to the wide variety of sensory symptoms, neurosensory dysfunction also represents a mechanism to be considered. Some of the cutaneous nerve endings express TRPA1, a sensor of skin barrier insult, which is involved in a variety of physiological or cellular processes including nociception, itch and neurogenic inflammation. Regulation of such sensor activation is also an issue to consider to control neurosensory dysfunction. Coriander seed oil is a 100% virgin oil of coriander seeds and boasts a unique composition of fatty acids. The soothing effect of coriander seed oil on sensitive skins was investigated by studying its capacity to regulate NF-κB and TRPA1 activation. Coriander seed oil allowed the regulation of NF-κB activation induced by TNF-α in an in vitro model of inflammation in keratinocytes. It also regulated the activation of TRPA1 induced by allyl isothiocyanate in an in vitro model of keratinocytes-neurons co-culture. These results are in favor of a soothing effect of coriander seed oil.

Coriandrum sativum L. belongs to the Apiaceae family, which is cultivated in Dong Nai province, in this paper its seed oil of was studied. The essential oil was extracted by hydrodistillation. We used two methods for activating of hydrodistillation: conventional heating and microwave irradiating. Its physical and chemical indexes were measured. The chemical composition of this oil was identified by GC/MS and quantified by GC/FID. Linalool (75.51-77.21 %), and geranyl acetate (15.64-12.79 %) were the main constituents of the oil which were obtained in 0,32-0.39 % yield. The biological activity of this oil was reported.

Day by day cost of petroleum fuels are increasing and more consumption of fossil fuel leads to rapid drain. Its right time to concentrate on production of the alternate energy source from edible and non-edible oil seeds. Recent trend is that the biomass is converted into bio-fuel and biogases. The following emission characteristic of Hydrocarbon (HC), Nitrogen oxide(NO), Carbon dioxide(CO2), Particulate matters, Carbon monoxide(CO) are investigated in this paper. In this exploration coriander seed oil Methyl ester is prepared by transesterification method using single cylinder VCR engine . Potassium hydroxide is used as catalyst.

Aryl hydrocarbon receptor (AHR) is an important regulator of skin barrier function. It also controls immune-mediated skin responses. The AHR modulates various physiological functions by acting as a sensor that mediates environment–cell interactions, particularly during immune and inflammatory responses. Diverse experimental systems have been used to assess the AHR’s role in skin inflammation, including in vitro assays of keratinocyte stimulation and murine models of psoriasis and atopic dermatitis. Similar approaches have addressed the role of AHR ligands, e.g., TCDD, FICZ, and microbiota-derived metabolites, in skin homeostasis and pathology. Tapinarof is a novel AHR-modulating agent that inhibits skin inflammation and enhances skin barrier function. The topical application of tapinarof is being evaluated in clinical trials to treat psoriasis and atopic dermatitis. In the present review, we summarize the effects of natural and synthetic AHR ligands in keratinocytes and inflammatory cells, and their relevance in normal skin homeostasis and cutaneous inflammatory diseases.
