“…The influence of minerals on the stability and content of unsaturated acids in medicinal plants and oils is mentioned in the literature. Zhang et al [56] reported a significant decrease in the content of unsaturated C18 acids with low unsaturation degree in the oil of Paeonia ostii seeds as the content of Cu 2+ increases in the soil, but especially as result of accumulation in the plant. This is explained by the prooxidative character of Cu 2+ on unsaturated FAs with a significant positive correlation between peroxides of linoleic and linolenic acids and Cu in plant.…”

BACKGROUND: Lycium barbarum L. has received considerable attention due to nutritional value of berries and its cultivation in Europe has attracted growing interest. OBJECTIVE: The aim of the study was characterization of Lycium barbarum L. berry cultivated in North Macedonia in terms of nutritional and functional properties and comparison with Lycium chinense M. variety. METHODS: Minerals, total proteins, sugars, antioxidant activity, fatty acids, carotenoids and polyphenols were determined and lipid indices were evaluated. Principal Component Analysis was used to describe variability of composition, while heat map to recognize the parameters significantly different for varieties. RESULTS: Lycium barbarum L. cultivated in North Macedonia represents a rich source of K, Cu, Mn, P, Zn, Mg, Fe and antioxidant compounds. Polyunsaturated fatty acids (mainly linolenic acid) were dominant in oil resulting in very low atherogenic and thrombogenic indices. A variability of 35.1% was ascribed to minerals, carbohydrates and proteins, 22.3% to ω-6 fatty acids and lipid indices of oil, 19.4% to nutrients with antioxidant activity and 13.4% to ω-3 fatty acids (n-3 and n-3/n-6 ratio). CONCLUSIONS: Chemometric analysis highlighted significant differences in terms of inorganic nutrients, antioxidant capacity, proteins, sugar profile and lipid indices in Lycium barbarum L. compared to Lycium chinense M.

“…The earlier mentioned results showed that the seven oligostilbenes were the majority of the total oligostilbenes, and could be used to evaluate the content of the main oligostilbenes in the seed shell of P. ostii . Oligostilbenes were considered to be the characteristic component in the seed shell of genus Paeonia with a wide range of biological activities . Therefore, for the first time the content of the seven oligostilbenes in the seed shell of P. ostii were simultaneously determined in this study.…”

“…Oil tree peony is a new type of tree peony cultivar where the seed kernels can be used for the preparation of edible oil, and P. ostii or P. rockii are the only two oil peony cultivars authorised by the Ministry of Health of the People's Republic of China in March 2011 . The plantation area of oil tree peony is very large at present due to the high oil content (varies from 24.12% to 37.83%) in peony seed kernels and the high unsaturated fatty acid content (more than 90%) in peony seed oil …”

Introduction The Paeonia ostii T. Hong & J. X. Zhang seed shell, characterised by a high content of oligostilbenes, is one of the two most important by‐products in the preparation of seed oil. Oligostilbenes are considered characteristic constituents of the genus Paeonia, and can be used in fingerprinting to determine the geographical origin and the quality of raw materials. Objective To develop and optimise a simple and reproducible high‐performance liquid chromatography diode array detection (HPLC‐DAD) method for the simultaneous determination of seven oligostilbenes in P. ostii seed shell from different geographical areas, and to associate the cultivation area. Methodology A validated HPLC method coupled with a DAD detector was performed for the detection and determination of target compounds in the samples. Optimal chromatographic conditions were achieved using an Agilent Zorbax Eclipse SB‐AQ‐C18 column and a gradient elution with acetonitrile and potassium dihydrogen phosphate solution. Results The proposed quantitative method showed appropriate accuracy and precision, and was successfully applied to the routine analysis of seven oligostilbenes and the quality evaluation of 50 P. ostii seed shell samples. There were significant differences between the contents of the seven oligostilbenes in different samples (P < 0.01). Conclusion The results demonstrated that the oligostilbenes were main secondary metabolites in the P. ostii seed shells, and the content of seven components in P. ostii seed shells sourced from different cultivation areas in China was different.

“…Plants growing in contaminated soils showed a decline in progress, enactment and harvest (El-Adawy and Taha 2001). Zhang et al (2015) observed those factors which can impact on the quality and composition of oil of peony seeds, cultivated in the traditional excavating agriculture area in 30 cultural field sites. They described considerably destructive relationships in between Cu content in soils or leaves and linoleic and unsaturated fatty acids.…”

This article discussed the impact of metal toxicity on chemical composition of seeds of Spinacia oleracea and Luffa acutangula. The impact of metals on seeds chemical composition was remediated through surface science technology using potato peel charcoal. The greenhouse pot experiment conducted in replicates in randomized block design under natural environment viz (a) control, (b) toxic metal-contaminated plants and (c) treated plants through potato peel charcoal. The analysis of chemical composition of harvested seeds revealed that the quality of seeds of plants related to the presence of pollutants in irrigated water. The reduced contents of amino acid, carbohydrates, proteins and lipids in seeds of Cu-contaminated plants directly linked with reduced moisture contents followed by low conservation and storage for embryo development. The reduced photosynthetic activities, carbohydrates and reducing sugars in next-generation plants grown from contaminated seeds showed reduced growth rate which were the consequences of the reduced storage material of polluted seeds. While the significance of clean water through surface science technology was evident on storage material of seeds and in next-generation plants. Editorial responsibility: M. Abbaspour.
