“…ese varying abiotic conditions, as seasonal fluctuations of chemical and physical water composition (e.g., nutrients, temperature, and salinity), are challenging for the biota and affect the species assemblages and ecosystem stability [2]. e different secondary metabolites produced by the plants are influenced by environmental conditions such as extreme light, water, soils, salts, chemicals, temperature, and geographical variations [3].…”

e chemical composition of Aloe vera growing in the small town of San Andrés de Pica, an oasis of warm waters and typical fruits, located in Tamarugal province in the Northern Chilean region of Tarapacá is reported. e chemical characterization was performed using liquid chromatography (UHPLC) coupled to PDA and high-resolution mass spectrometry (HESI-Q-Orbitrap ® -MS) in four different plant parts of Aloe (peel, flowers, gel, and roots). Twenty-five phenolic compounds were identified, including cinnamic acids and other derivatives (e.g., caffeic and chlorogenic acids), chromones (e.g., aloesin and isoaloeresin D), anthracene compounds and derivatives (e.g., aloin A/B and emodin), and several C-flavonoids (e.g., orientin and isovitexin), among others. Total antioxidant activity of the ethanolic extracts of the peels, flowers, gel, and roots was measured as the capturing of the DPPH • and ABTS •+ radicals, while the iron-reducing antioxidant power (FRAP) was measured by spectroscopic methods. e peel had the highest antioxidant activity with values of 2.43 mM ET/g MF (DPPH • ), 34.32 mM ET/g MF (ABTS •+ ), and 3.82 mM ET/g MF (FRAP). According to our results, the peel is the best part of the plant for the production of nutraceuticals or cosmetics products for its greatest number of bioactive compounds. is is a new and innovative finding since the only part used in traditional medicine is the gel of Aloe, and the peel is generally considered waste and discarded.

“…Because these plants may have lost their original behavior, their wild behavior cannot be inferred from the currently cultivated specimens. 1,7 Specific in situ and in locus studies are mandatory for better understanding of the chemical behavior and more thorough appreciation of the variation in metabolite concentrations of wild plants in tropical ecosystems. This information is necessary for both evolutionary and chemotaxonomic studies and shall assist expansion of the current knowledge about the ecological interactions taking place between a certain plant and its surroundings.…”

Recebido em 7/5/12; aceito em 18/9/12; publicado na web em 26/10/12The species Eremanthus mattogrossensis, known as "veludo do cerrado" (cerrado velvet), is native to the Brazilian Cerrado.Because the amount of metabolites present in plants may be influenced by biological and environmental factors, here we conducted an HPLC-DAD-MS/MS investigation of the metabolite concentrations found in the MeOH/H 2 O extract of the leaves of this species. The main compounds were identified and quantified, and the metabolites were grouped by chemical class (caffeoylquinic acids, flavonoids, and sesquiterpene lactone). Statistical analysis indicated a straight correlation between the quantity of metabolites and seasonality, suggesting that environmental properties elicit important metabolic responses.

Zilla spinosa is one of the dominated woody perennial shrubs widespread in the Egyptian Red sea coastal desert, belonging to family Brassicacea. Z. spinosa is used as a folk medicine and for heating by local people. Z. spinosa inhabits arid habitats exposed to adverse climatic changes which influence the production of the bioactive natural products. The natural secondary products have significant importance for plant acclimatization to the arid habitats beside their significant practical application in medicinal, nutritive and industrial purposes. The accumulation levels of some natural products including phenols, tannins, glucosinolates, flavonoids, saponins, proanthocyanidins and cardiac glycosides were measured in Z. spinosa inhabiting different locations of Wadi Hagul during spring and summer seasons. The results of the current study showed that Z. spinosa grown in the adverse environment has adapted to cope with extreme temperature, water deficit and geoclimate changes especially in summer, by enhancing the accumulation of some antioxidant compounds including phenols, tannins, glucosinolates, flavonoids, saponins, cardiac glycosides, concomitant with increments in the total antioxidant capacity and PAL activity. Consequently, Z. spinosa shrubs inhabiting the arid environment is a promising new source of saponins, glucosinolates, cardiac glycosides, phenols and flavonoids which could participate in drug development and exploration of alternative strategies to increase productivity of wild plants.
