In order to investigate the differences in the chemical composition of Dendrobium officinale at different altitudes, we collected Dendrobium officinale from different altitudes in Guizhou Province, China, and firstly determined its polysaccharide content by using a sulfuric acid-phenol color development method with reference to the Chinese Pharmacopoeia, and further determined its metabolites by using widely targeted metabolomics, and explored the differences in the chemical composition of Dendrobium officinale at different altitudes using multivariate statistical analysis. We found that the polysaccharide content was higher in plants growing at 1122 m, a total of 902 secondary metabolites were detected by wildly targeted metabolomics, and amino acids and their derivatives were more highly expressed at 1122 m, while other metabolites were more highly expressed at 835 m. Furthermore, we found that the phenolic acid compound nerugein was only present in plants at 835 m, and two lipid compounds, namely Lyso PE 20 : 4 and its isomer, were only present at 1122 m. Taken together, these results may provide a basis for the selection and clinical application of D. officinale cultivated at different altitudes.

The Colombian Amazon is a megadiverse region with high potential for commercial use in the pharmaceutical, food, and cosmetic industries, constantly expanding and looking for new alternatives from natural resources; unfortunately, few characterization reports of its profitable non-timber species in Colombia have been conducted. This work aimed to perform a comprehensive analysis of traditionally used species: Carapa guianensis (Andiroba), Euterpe precatoria (Asai), Mauritia flexuosa (Miriti), Astrocaryum murumuru (Murumuru), Plukenetia volubilis (Sacha Inchi), and Caryodendron orinocense H.Karst (Cacay). For this purpose, oil and fat quality indices, phytosterol, carotenoid, tocopherol, and tocotrienol content, as well as density and refractive index, were measured to establish their quality level. Multivariate analysis showed four groups of samples; such differences were mainly due to the composition rather than quality indices and physical properties, especially the content of saturated and unsaturated fatty acids. All species reported a precise composition, which makes them noninterchangeable, and Miriti oil arose as the most versatile ingredient for the industry. The Colombian Amazon region is a promising source of quality raw material, especially for oils/fats and unsaturated fatty acids; this resulted in the most interest for pharmaceutical, food, and cosmetic purposes.

“…These chemicals are conjugated and allene FAs that cells produce in response to specific adverse conditions. Some investigations have shown that conjugated FAs are formed during salt and UV stresses [ 2 , 23 ]. It should be noted, however, that both soil salinity and elevated UV can cause the development of reactive oxygen species (ROS) in cells, promoting oxidation and the consequent change of double bonds in acyls.…”

“…The presence of conjugated double bonds in FA acyls alters the physical properties of lipids containing them, which may help algae and higher plants adapt to demanding environments (for example, by dissipating intense light flux in high-altitude terrains [ 2 ]). Conjugated FAs appear to be a viable building material for liposome synthesis, which, in addition to their fundamental applications [ 3 ], are being intensively studied as transporters for targeted drug delivery [ 4 ], including cancer treatment [ 5 ].…”

The microalgae Vischeria sp. IPPAS C-70 produces eicosapentaenoic acid. Several stresses cause the formation of fatty acid peaks that resemble hexadecadienoic acids. We used the integrated technique including TLC, HPLC, and GC–MS to search and determine these fatty acids. Double bond positioning in these fatty acids indicated that they were conjugated dienes and allenes. We identified and described natural nine isomers of C16 polyunsaturated fatty acids, including common methylene-interrupted dienes (Δ6,9-16:2, Δ7,10-16:2, Δ9,12-16:2), and unusual conjugated dienes (Δ6,8-, Δ7,9-, Δ8,10-, Δ9,11-, and Δ10,12-16:2), as well as allenic diene (Δ9,10-16:2). We hypothesize that the formation of conjugated dienes and allenes among fatty acids is the result of oxidative stress caused by H2O2. Hydrogen peroxide also caused an increase in saturated at the expense of unsaturated fatty acids, suggesting inhibition either fatty acid desaturases activities or the corresponding gene expression.
