“…However, our results diverge from those published by other studies (18). Generally, the observed differences in chemical composition of rose geranium oils, when compared with those reported in previous studies could be due to a number of factors, including differences in climatic conditions and geographical locations, season at the time of collection, and fertilization (17, 19).…”

BackgroundSince the available anti-inflammatory drugs exert an extensive variety of side effects, the search for new anti-inflammatory agents has been a priority of pharmaceutical industries.AimsThe aim of the present study was to assess the anti-inflammatory activities of the essential oil of rose geranium (RGEO).MethodsThe chemical composition of the RGEO was investigated by gas chromatography. The major components were citronellol (29.13%), geraniol (12.62%), and citronellyl formate (8.06%). In the carrageenan-induced paw edema, five different groups were established and RGEO was administered orally in three different doses.ResultsRGEO (100 mg/kg) was able to significantly reduce the paw edema with a comparable effect to that observed with diclofenac, the positive control. In addition, RGEO showed a potent anti-inflammatory activity by topical treatment in the method of croton oil-induced ear edema. When the dose was 5 or 10 µl of RGEO per ear, the inflammation was reduced by 73 and 88%, respectively. This is the first report to demonstrate a significant anti-inflammatory activity of Algerian RGEO. In addition, histological analysis confirmed that RGEO inhibited the inflammatory responses in the skin.ConclusionOur results indicate that RGEO may have significant potential for the development of novel anti-inflammatory drugs with improved safety profile.

Essential oils of various plants can be effective at repelling mosquitoes. The repellent properties are often ascribed to their dominant constituents. Our objective was to analyse several essential oils by coupled gas chromatographic‐electroantennographic detection (GC‐EAD) on the premise that those compounds that are detected by the antennae of the yellow fever mosquito, Aedes aegypti L. (Diptera: Culicidae), are candidate repellents even though they may be minor constituents and thus be overlooked in GC‐mass spectrometric analyses of essential oils. In the essential oils of catnip, cinnamon, citronella, cumin, eucalyptus, geranium, ginger, melissa, peppermint, rosemary, and thyme, 42 components induced antennal responses, most commonly β‐caryophyllene, linalool, 1,8‐cineole, geraniol, and geranial. Some of these 42 components are known insect repellents, indicating that GC‐EAD screening of essential oils is a viable analytical technique to detect quantitatively minor constituents, which could be potent repellents when tested at an appropriate dose.

“…While China and Egypt are the major producers of pelargonium volatile oils, the Bourbon geranium from Reunion Island is considered as one of the highest quality essential oils [11][12][13][14][15][16]. The oils are characterized by high levels of citronellol, geraniol, isomenthone, linalool accompanied by wide range of esters, such as citronellyl formate, geranyl formate, geranyl acetate, geranyl propionate and sesquiterpenes, of which 10-epi-γ-eudesmol and guaia-6,9-diene are the most important [16,17]. Very valuable in high grade perfume chemical aromas obtained from Geraniaceae family is rhodinol (a mixture of geraniol, citronellol and other alcohols) [18].…”

Plants have been used for their aromatic and medicinal purposes for centuries. The genus Pelargonium contains about 250-280 species and cultivated around the world for the production of essential oils and absolutes. Pelargonium species are remarkable for their odour diversity, from fresh, lemon and minty scent, through floral, rose, fruity up to spicy and camphoreous smell as well as many health beneficial properties, that is why their essential oils are widely used in perfume, cosmetic, food and pharmaceutical industries. The aim of this study was to determine variability in populations of Pelargonium genus by evaluating their differences in quantitative and qualitative essential oils compositions. This study determined that of all the examined essential oil, the one of P. graveolens indoor cultivar has the closest C:G ratio (1.16) which makes it a very valuable product. In comparison with available literature, beside the geographical region of plant growth, all essential oils from P. graveolens contain a diverse range of compounds, nevertheless, in every single one, geraniol and citronellol are present in the most significant fraction of the total oil. The examined P. roseum essential oil was characterized by the highest level of citronellol (44.62 % of total oil), but it can be due to the chemical reactions (conversion geraniol into citronellol) occurring in stored product.
