“…Previous studies have also revealed that the chemical polymorphism of essential oils of Hyptis, 33 Thymus, 34 Baccharis, 35 Lychnophora, 36 and Eugenia species vary significantly under different environmental abiotic factors, 37 such as temperature, latitude, moisture, and chemical soil composition. It has also been reported that abiotic conditions such as soil nutrients, water stress, pollution, light, and altitude can affect the production of plant phenols and tannins.…”

“…Such misclassification could be caused by a higher level of a-eudesmol and b-eudesmol in the sample, which is a feature of the S1 sampling site. Percentages of oil constituents/total phenol and tannin contents, as well as soil parameters in clustered samples are shown in a supplementary information file (see SI, Tables S4 and S5, respectively).Previous studies have also revealed that the chemical polymorphism of essential oils of Hyptis, 33 Thymus, 34 Baccharis, 35 Lychnophora, 36 and Eugenia species vary significantly under different environmental abiotic factors, 37 such as temperature, latitude, moisture, and chemical soil composition.

O conteúdo foliar de fenóis totais e de taninos, bem como a composição química dos óleos essenciais em populações de Myrciaria cauliflora cultivadas em seis diferentes sítios de amostragem indicou a presença de quatro grupos de amostras de acordo com as características químicas da folha e do solo de cultivo. O grupo I incluiu as amostras oriundas do solo franco-arenoso (S1), caracterizado pela maior e menor percentagem de g-eudesmol (11,55%) e germacreno D (20,48%), respectivamente, e alto conteúdo de fenóis totais (136,68 mg g -1 ) e taninos (60,72 mg g -1 ). O grupo II, rico em elemol (4,61%), incluiu as amostras cultivadas nos solos franco-arenoso-argilosos (S2, S3 e S6), enquanto que as amostras dos solos argilosos S4 (grupo III) e S5 (grupo IV) apresentaram as mais elevadas percentagens de germacreno D (III: 27,20%; IV: 26,83%) e os mais baixos teores de elemol (2,12-2,55%), fenóis totais (79,69 e 111,77 mg g -1 ) e taninos (34,04 e 44,51 mg g -1 ). A análise de redundância canônica revelou como o balanço de nutrientes do solo e das folhas influenciou a distribuição dos constituintes químicos nos diferentes agrupamentos. A variação química parece ser determinada por fatores ambientais.Foliar contents of total phenols and tannins and the essential oil composition of Myrciaria cauliflora populations cultivated in six sampling sites have shown the presence of four clusters related to soil types and foliar nutrients. Cluster I included samples which originated from sandy loam soil (S1) with the highest and lowest percentages of g-eudesmol (11.55%) and germacrene D (20.48%), respectively, as well as high total phenol (136.68 mg g -1 ) and tannin (60.72 mg g -1 ) contents. Cluster II, rich in elemol (4.61%), included all the samples cultivated from clay sand loam soils (S2, S3, and S6), whereas clay soils S4 (cluster III) and S5 (cluster IV) had the highest amounts of germacrene D (III: 27.20%; IV: 26.83%) and the lowest levels of elemol (2.12-2.55%), total phenols (79.69 and 111.77 mg g -1 ), and tannins (34.04 and 44.51 mg g -1 ). The canonical redundancy analysis revealed the relationship between chemical balances in the soil and leaf nutrients in different clusters. Chemovariations may be environmentally determined.Keywords: Myrciaria cauliflora, essential oil, phenol, chemical variability, environmental influence, multivariate analysis Introduction Jaboticaba, also known as guaperu or sabara, is a small native Brazilian fruit of the cauliflorus Myrtle (Myrtaceae). It is grape-like in appearance and texture, although its skin is thicker and tougher, and its color varies from grown to deep purple or black due to high anthocyanin content. 1 The ripened berries are highly perishable -postharvest decay occurs within 2-3 days -which is a problem for both transport and storage. 2 The plant is distributed in southern and central Brazilian regions and consists of about nine species of trees and shrubs, among which Myrciaria cauliflora (Mart.) O. Berg. and M. jaboticaba (Vell.) O. Berg. are the most widely cultivated ...

“…Tous ces facteurs peuvent avoir influencé sensiblement les paramètres physico-chimiques et le profil chimique de l'huile essentielle du Pelargonium asperum comorien. D'ailleurs, les huiles essentielles de plusieurs espèces de plantes ont présenté des compostions chimiques différentes selon leur origine (Rajeswara et al, 1996 ;Boira & Blanquer, 1997 ;Barnola & Cedeno, 1999 ;Loziene & venskutonis, 2004 ;Curado et al, 2006 ). Ainsi, l'huile essentielle de Pelargonium asperum des Comores n'aura pas les mêmes propriétés physico-chimques et la même bioactivité que celle des autres pays.…”

Résumé.-Les parties aériennes de Pelargonium asperum ou Pelargonium graveolens (géranium Bourbon) récoltées en pleine floraison à Ndrondroni-Mvouni, Grande Comore, ont donné un rendement de 0,4% d'huile par rapport à la matiè-re sèche. Soixante et un composés ont été identifiés par CPG et CG-SM et constituent un total de 99,96% de l'huile de géranium Bourbon. Les principaux constituants sont le citronellol (29,98%), le géraniol (14,12%), le formiate de citronellyle (9,09%), l'isomenthone (7,80%) et le linalol (5,97%). L'activité antifongique de l'huile essentielle est plus importante que l'activité antibactérienne. L'huile de géranium s'est révélée fortement antioxydante par inhibition des radicaux libres.Mots clés : Pelargonium asperum -rendement -antifongique -antibactérien -radicaux libres -antioxydant -composition chimique.Abstract.-The aerial parts of Pelargonium asperum or Pelargonium graveolens (geranium Bourbon) harvested in full bloom in Ndrondroni-Mvouni, Grande Comore, provide a yield of 0.4% of oil in relation with dry material. Sixty-one compounds were identified by GC and GC-MS and constitute 99.96% of the geranium bourbon oil. The main constituents are citronellol (29.98%), geraniol (14.12%), citronellyl formate (9.09%), isomenthone (7.80%) and linalool (5.97%). The antifungal activity of essential oil is higher compared antibacterial activity. The geranium oil was strongly inhibits free radicals.

“…Chemical polymorphisms or chemotypes have been reported for many medicinal plants (Mockute et al, 2001;Russell and Southwell, 2003;Curado et al, 2006). Douglas et al (2004) conducted a study to determine whether triketone rich chemotypes of Leptospermum scoparium are present in New Zealand and define the boundaries of chemotypic variation.…”

Chemotypic variation of essential oils in the medicinal plant, Anemopsis californica

Anemopsis californica (Saururaceae) commonly called yerba mansa, is an important medicinal plant in many deserts in the southwestern region of North America. Populations of A. californica, collected throughout New Mexico, were examined for chemical variability in roots and rhizomes for select monocyclic (cymene, limonene, piperitone and thymol) and bicyclic (α-pinene, 1,8-cineole and myrtenol) monoterpenoid and phenylpropanoid (methyleugenol, isoeugenol and elemicin) derived essential oil components. Three distinct chemotypes were detected using a hierarchical clustering analysis on the concentration of 10 different analytes in three individuals from each of 17 populations. One chemotype was characterized by high elemicin concentrations, a second chemotype by high methyleugenol concentrations and the third by high piperitone and thymol concentrations. Steam distilled oil was used to screen for anticancer bioactivity. A. californica root oils demonstrated antiproliferative activity against AN3CA and HeLa cells in vitro but no activity against lung, breast, prostate or colon cancer cells. The IC 50 values for the root oil were 0.056% and 0.052% (v/v) for the AN3CA and HeLa cells respectively.
